Hobbing Process


Hobbing Process

A basic description of the gear hobbing process:

Gear hobbing a generating process in that the form of the gear space is not a one to one reproduction of the

hob tooth form. The generating process requires an accurate timed relationship between the rotation of the part

being cut and the hob rotation, based on the number of hob threads. For example if a 40 tooth gear is being

cut by a single thread hob, for each revolution of the hob, the part must rotate to advance one tooth angle. For

a two thread hob, the part would rotate twice as fast. The generating process also means that the hob teeth are

advancing into the gear space in a sequence. Each sequential cut of the straight edge of the hob tooth begins to

generate a curved surface of the involute form of the gear. The spacing of the sequential cuts is dependant on the

number of gashes (rows of teeth), and number of threads in the hob, and the number of teeth being cut.

As the hob and gear rotate in the timed relationship the hob also feeds along the axis of the gear, removing

material from the spaces and generating to involute curvedtooth form.


6/52

Mult ip le Thread Hobs

Multiple Thread Hobs

The use of multiple thread hobs can make an enormous improvement in the productivity of the gear cutting

process. The advantage afforded by the multi-thread hob comes from the increased indexing speed of the work

piece. With a single thread hob, the part rotation advances one space for each revolution of the hob. With a two

thread hob, the part rotation advances two spaces for each hob revolution.

Cut Time =

The cutting time calculation above shows the number of hob threads in the denominator of the equation,

therefore if the number of thread is doubled the calculated time can theoretically be cut in half. Of course, to

accommodate the increased chip load on the multi-thread tool, you may need to reduce the feed rate. But the

overall cycle time will still be greatly improved.

Other factors also need to be considered when changing an application from single thread to multiple threads.The ratio of part # of teeth to hob number of threads, for example should be a prime number, if possible, to

minimize the impact of any thread errors in the hob causing index errors in the gear. If an even ratio, the thread

errors may be repeated in the part, but with a prime ratio each thread enters every part space, minimizing

the impact of the hob thread to thread accuracy. Of course, highly accurate class AA and AAA hob grinding

technology has also helped to minimize thread to thread errors in the tool.

Using multiple thread hobs is just one of the design factors involved with the overall process of optimizing

the hobbing application. Smaller hob diameters, longer shiftable length hobs, increased number of threads,

premium materials and coatings have all helped the OptiGash hobbing concept reduce your total cost per part

by attacking the machining cost.

E-Z Cut Roughing Hob


E-Z Cut Roughing Hob

The primary objective of the E-Z Cut roughing hob is the swift removal of metal to permit accurate and economical

nishing of the gear tooth pro le in a secondary operation. Conventional generating hobs use less than one third

of their tooth depth for about two thirds of the metal removal work. E-Z Cut hobs add extra cutting edges by

adding specialized utes. The additional utes equalize cutting effort and eliminate the problem of overworked

tip. Since there is a practical limit to the chip load a tooth can carry, it stands to reason that a hob with more

utes (in a given diameter) can feed faster through the work.

Besides adding extra cutting edges in the tip area, E-Z Cut hobs have a slight modi cation from the true involute

form to control chip size for easy removal. Dual pressure angles on the hob generate a slightly barrel-shaped

gear tooth form with relief on the ank and at the tip of the tooth. This gear tooth form is conducive to accurate

nishing of the gear.

Many large coarse pitch gears with high numbers of teeth require two (and sometimes three or more sharpenings

of a conventional hob before the roughing operation is completed This situation seldom occurs wit E-Z Cuthobs. The easy cutting action extends time between sharpenings, saving sharpening time and costs.

The sharpening of the E-Z Cut hob is relatively easy, even though there are different depths of gash. The method

used for sharpening is to index sharpen all teeth to the shallowest depth. Next, set up for the deeper teeth, index

sharpening them by blending in the sharpening with the previously sharpened shallow depth of gash.

All the advantages of the E-Z Cut hob geometry are quite compatible with the universal use one expects from

standard conventional hobs. An E-Z Cut hob with normal diametral pitch and pressure angle can cut any range

of teeth in pinions or gears with like pitch and pressure angle.

As with any conventional hub, the E-Z Cut may be furnished as single or multiple thread. In either design,

cutting ef ciencies are improved, thus releasing more productive machine time for the nishing operation.

Carbide Hobs

Carbide Hobs

Since the right choice for optimizing your application isnt always evident, let Gleason Cutting Tools

Corporation help determine whether you should hob wet or dry, with HSS or carbide tools, with single or

multilayer coatings.

Our experience with carbide cutting tools dates back to 1966. Improvements in carbide materials since that time

have dramatically improved its performance for hobbing applications.

Gleason Cutting Tools Corporation can provide carbide hobs in either ISO K or P grades. ISO K grades of

carbide are a simple two-phase composition consisting of tungsten carbide (WC) and cobalt (Co). A K-Grade

carbide is suited to cutting soft (160-200Hb) or hard hobbing (40-55Rc) ne module parts from solid, or for

skive hobbing materials (52-64 Rc), with a fully coated tool. For reconditioning, the K-Grades of carbide can be

stripped of coatings, resharpened and must be recoated with a fully coated face.

ISO P grades of carbide are threephase alloyed compositions consisting of tungsten carbide (WC), cobalt

(Co) and cubic carbides. The cubic carbide binders can be titanium carbide (TiC), tantalum carbide (TaC) and

niobium carbide (NbC).

A P grade carbide is for soft cutting applications up to 370 Hb, where recoating is not desired. For reconditioning,

only resharpening of the worn cutting face is required. P-grades cannot be stripped of coatings.

Worm Gear Hobs


Worm Gear Hobs

Gleason Cutting Tools Corporation makes HSS hobs for cutting worm gears which mate with non-enveloping

worms. They can be single or multiple-thread, bore type or shank type, topping or non-topping, radial or

tangential feed type of tools. Depending on nished gear accuracy speci cations, worm gear hobs may be

supplied either unground or ground, for roughing or nishing.

The manufacturing of worm gears, like any hobbing process, has many variables that must be evaluated,

monitored, and controlled to achieve the desired quality part. The worm gear design is strictly tied to the

design of the mating worm and its manufacturing process. The worm gear hob design likewise must take into

consideration the worm manufacturing process and accuracy.

The Worm Gears are cut on a hobbing machine using one of the four types of hobbing processes and respective

hob designs. Most commonly, the direction of hob feed can be radial, or in a tangential direction, but the hob

does not feed axially across the worm gear face width.

A radial feed worm gear hob is the most common. The

hob feeds radially to depth and the part rotated enough

times to complete the cutting of all teeth. This method

can be used for all cutting gear to thread ratios.

A tangential feed hob process feeds the hob axially,

parallel with the hob axis on a line tangent to the outside

diameter of the worm gear. The hob moves at a slow

feed rate. This method can be used primarily on ratioswhere gear teeth to worm threads are 6:1 or less to

produce an extremely smooth gear pro le.

A radial-tangential type feed hob . The hob is fed

radially to depth and then fed tangentially to achieve a

smooth pro le. The worm gear hob is designed slightly

larger than the worm, providing a contact pattern near

the center of the gear face width. As the hob is sharpened

back until it is the same size as the worm, the bearing

contact pattern gets wider across the gear face width.

Fine P i tch Gear Hobs

Fine Pitch Gear Hobs

According to the American Standards Association and the American Gear Manufacturers Association, gears 20

diametral pitch and ner are ne-pitch gears. Types of ne-pitch hobs available include nishing and semi-

nishing, topping and non-topping, ground and unground, standard and special, multiple thread and carbide.

These hobs can be made to ANSI tolerance classes AA through C. Equivalent classes from other tolerancing

standards may be applied if requested.

One of the primary differences between ne-pitch and coarse-pitch hobs is the provision for a greater

percentage of clearance in the ne-pitch series. Prior to the adoption of the ne-pitch system, clearance at the

root of the gear tooth was insuf cient and caused unsatisfactory gear operations in some cases. The clearance

was increased to eliminate possible interference with the mating part.

Interference can sometimes be caused by normal hob wear. When the corners of the hob tooth become slightly

worn, the hob may not cut the correct form to the required depth, causing interference at this point. Althoughthis type of wear occurs on all hobs, it is not proportionately as great on coarse-pitch hobs as on the ner

pitches. Clearance is added by increasing the hob addendum. The standard practice is to increase the height

above the pitch line. Thus, even if the corners of the tooth become slightly worn, the correct gear tooth form

extends beyond the working depth of the tooth, eliminating interference with the outside corners of the

mating tooth.

Hob Mount ing Errors


Hob Lead

A theoretically perfect hob, manufactured error free, can produce pro le errors if mounted incorrectly on the

hobbing machine arbor. A hob that is mounted incorrectly can exhibit a condition known as runout. Traditional

runout is in phase. An out of phase runout condition is known as wobble. Runout introduced through poor hob

mounting can destroy the hobs accuracy.

To eliminate runout, hobs are designed with hubs to provide a qualifying surface. Hubs are used to true up the

hob on the arbor. Since hubs are held in relation to the form on the hob teeth, truing the hubs makes the hob

rotate about the proper axis. Hub runout causes errors in the part tooth form since the hob teeth are not in the

proper position relative to the generating pitch line.


12/52


Hob Lead

The gures below illustrate the effects three types of hob runout have on the gear tooth form. These are most

often created by:

Failure to true up the hob arbor

Failure to true up the hob on the arbor by indicating the hubs on the ends of the hob

Bent hob arbor

Oversize hob bore or undersize hob arbor

Non-parallel hob clamping spacers

Misaligned or worn outboard support bearing for hob arbor

Hob runout error due either to careless mounting or improper sharpening is the greatest contributor to poor

hobbed involute pro les.

Hob Sharpening Errors

A perfectly accurate hob, with a proper setup, on an accurate machine with good tooling can cut a bad gear if

the hob is improperly sharpened. Sharpening errors that affect hob and gear accuracy are as follows:

Rake angle error

Index error

Flute lead error

Rake Angle Error

The hob cutting face is designed to lie in a speci ed plane and any variations of the actual hob from that plane is

considered ute cutting face error. This error is measured from the outside diameter to the cutting depth.

Negative rake error occurs when too much stock is removed from the upper portion of the tooth face. Incorrect

negative rake decreases the depth and increases the pressure angle on the hob tooth.

Negative rake error results in cutting drag and a gear tooth that is thin at the top and thick at the bottom. The

effect of negative rake is an involute chart that leans in the positive direction.

SHARPENING ERROR Cutting face ground with negative rake when it should be radial.

Effect of negative rake resharpening error on prole.

Shaper Cutters

Shaping is often the preferred process for the pre- nishing and nishing of nonhardened internal gears and for

producing shoulders and special pro les.

Gleason Cutting Tools offers a complete range of highly productive and cost-effective shaper cutters all

produced with maximum precision and consistent high quality on new state-of-the-art production equipment.

This is essential, since the quality of the shaper cutter, and variations in pitch and concentricity in particular, are

ultimately re ected in the machined gear.

Our exclusive Isoform generating process rolls the cutter from side to side as the pro led grinding wheel

reciprocates through the tooth space. This method generates both sides simultaneously, resulting in a truer

cutting geometry and higher quality of gears and other shaped forms through the life of the cutter.

Shaper cutters are custom made to your application. To get the process started, please submit the Shaper Cutter

RFQ, or e-mail us at [email protected].

Shaping Process

The gear shaping process is a generating process that involves reciprocating a tool that resembles a mating gear

to the gear being produced. While the tool is being reciprocated up and down, it also rotates in a timed relationship with

gear based on the index ratio of the number of teeth in cutter and the desired number of teeth in the gear. As

the cutter and gear are rotating, the centerdistance is gradually reduced, causing the cutter to engage in cutting

material from the spaces of the gear. As the cutter to part center distance reduces, the cutter reaches full depth of

the gear teeth, and then one full revolution of the part will complete the shaping process.

For helical gears and additional twisting motion is required to cause a helix angle to be generated onto the gear.

This twisting motion is imparted by either a mechanical helical guide on the machine or by a CNC axis of the

machine.

The versatility of the shaping process lends it to cutting internal as well as external gear forms. In addition, two

or more cutters can be tandem mounted on the cutter spindle adaptor to cut more than one component on a shaftor cluster gear.

Shaping can be used for cam forms, single index cutting of slots, keyways, or ratchet forms. Sector gears can be

cut by the shaping process. A special type of internal shaper cutters called an Enveloping Cutter can be designed

to produce an external gear that is recessed inside of a component. Virtually any form that is spaced around a

circle can be cut by a shaping process. Modern shaping equipment and specially designed shaper cutters have

made high speed shaping a very productive and accurate gear cutting process.

Isoform Shaper Cutters

Gleason Isoform Shaper Cutters produce the original part form accuracy, even after repeated sharpening. The

Gleason Shaper Cutter is through-generated by our Isoform grinding process which produces the correct form

geometry from the front face to the back face of the cutter tooth.

COMPARING THE DIFFERENCE

The traditional grinding process, which is used to

form the teeth of conventional shaper cutters, rocks

the cutter against one side of a stationary grinding

wheel as shown in Figures 1 & 2 to the right,

imparting the curvature of the wheel into the form.

The grinding wheel remains in a xed position

midway through the cutter. Teeth are rst ground

on one ank all the way around. The cutter is thenremoved from the grinder, reversed, then replaced

on the machine to grind the other ank.

With the Gleason grinding process shown in

Figures 3 & 4 below, the Isoform Shaper Cutter is

rocked from side to side against a grinding wheel which carries the basic rack form. At the same time, the

wheel reciprocates rapidly through the entire length of the cutter, front to back. As a result, both anks are

generated simultaneously.

THE ADVANTAGES TO GLEASON GRINDING PROCESS.

Positive cutter concentricity.

Grinding both anks of the cutter simultaneously in the same machine setup helps assure symmetry of the

tooth form. Centering errors are eliminated. All teeth are of uniform thickness and spacing.

Through-grinding process maintains correct cutter tooth geometry.

Through-grinding generates a smooth pro le of correct shape along the full length of the cutter tooth.

Therefore, any involute modi cations traditionally prone to radical change as the cutter is sharpened back

remains within tolerance. This provides a much longer usable tooth life.

Generated tip contour.

The generated tip contour in turn generates smooth and consistent gear tooth lets. Gears in existing designs

can be made consistently stronger. New gear designs can be more compact.

Stronger cutter tooth roots.

The through-stroking grinding process also produces tooth roots that are straight and free of excessive

deeps and shallows. The resultant cutter is less prone to breakage.

EXTENDED LIFE CUTTERS GIVE A LONGER USE ABLE TOOTH LENGTH .

The Gleason grinding process, with its unique reciprocating stroke, allows the production of Isoform to make

shaper cutters with the longest effective tooth length available anywhere. Our Extended Life Cutters have a

longer usable life than standard cutters, which allows for a lower tool cost per part produced. Special cutters

with modi ed forms or chamfering features bene t the most.

Standard Gear Milling Cutters

Standard gear milling cutters can be designed with either a ground or unground form to produce spur or helical

gear teeth, bevel and mitre gear teeth, rack teeth and special gear tooth forms.

The tooth form of a standard gear milling cutter is a composite of the involute and cycloidal forms. The basic

rack shown in Figure 1 is the form that will be produced by a standard gear milling cutter, and all standard

Gleason Cutting Tools gear cutters are based on this form.

Unlike gear generating tools, gear milling cutters are not usable for all numbers of teeth. Instead, a standard gearmilling cutter is designed for cutting varying numbers of teeth within a certain range. Hence, the term range

cutter is commonly applied to these cutters.

Gears from 12 teeth to in nity (a rack) are covered by 8 designs for each pitch, designated by range numbers 1

through 8. The form of the cutter is made correct for the lowest number of teeth in that particular range. Thus,

all teeth within the range are provided with suf cient tip relief.

Gear cutters have been classi ed into eight different groups according

to the number of teeth to be cut. The number of teeth in spur gears

covered by each range is shown in the following table. They can be

provided with either a 141/2 or 20 pressure angle.

These cutters are usually considered as suf ciently accurate for most

work. However, the special half-size cutters listed to the right may be

used when a more accurate tooth form is required.

Helical gears can be cut by these same cutters. However, the range

number may not be the same as for a spur gear with the same number

of teeth. The number of helical teeth must be translated into an

equivalent number of spur teeth. The formula for determining theequivalent number of spur teeth is:

Equivalent number of spur teeth =

Where N = number of teeth in helical gear and = helix angle of gear.

The number of the cutter should be selected according to the equivalent number of spur teeth.

Whole depth (WD) marked on nishing gear cutters refers to the depth of cut as measured from the theoreticaloutside diameter of the gear. At this depth of cut, the cutter will produce a tooth thickness which will be one half

of the circular pitch. To provide for backlash between mating gears, one or both gears must be cut to a depth

greater than the whole depth marked on the cutter.

Gears of 12 or more teeth milled with standard nishing milling cutters of the proper range numbers will

operate together.

Gears cut by a standard nishing gear cutter will mesh properly with a gear produced by a hob with composite

form. They will not, however, mesh properly with a gear generated by a tool having a standard involute tooth

form.

Special Gear Milling Cutters

Gear milling cutters also can be designed to produce a true involute form on the gear teeth. This type of cutter

is required if the gear is to roll with a gear hobbed with a standard gear hob. Gear cutters for any pressure angle

can be made with the true involute form. Some form modi cations may be required for cutters designed for

gears with a small number of teeth and small pressure angle to assure satisfactory performance. The number of

the cutter for a range of gear teeth is the same as for the standard range cutters. For non-standard gears, such

as enlarged pinions, the cutter is made single purpose and does not follow the number designation.

Roughing Gear Milling Cutters

Roughing gear cutters are designed for rapid removal of metal. Such use requires various types of chip breakers,

depending mainly upon the amount of metal to be removed. The amount of stock left for nishing is nominally

.200/DP. The ve different styles of standard roughing cutters are shown below.

STYLE A

Style A has steps on both sides of all teeth and leaves steps on the sides of the gear teeth. Style A cutters areused primarily on gears of 4 DP or coarser.

STYLE B

Style B has chip breakers on only one side of each tooth, each succeeding tooth having steps on the alternate

side. This style of cutter leaves a smooth cut since the plain side of the teeth cleans up the grooves left by the

chip breakers. Style B cutters are normally used to cut gears from 4 DP TO 10 DP.

STYLE C

Style C has teeth which are smooth on both sides, and the teeth are not staggered. It is most commonly used

on gears of 10 DP or ner. Style C is also used for the roughing cuts on bevel gears and gears where the cutter

tooth must be very narrow at the tip.

STYLE D

Style D has teeth with chip breakers on both sides, three on one side and two on the other, alternating on every

other tooth. They are spaced so that there are no steps produced on the gear tooth pro le.

STYLE A1

Style A1 has proven to be very ef cient in cutting coarse-pitch gears. It is similar to style A in appearance,

but has side clearance on both sides and a 5positive radial rake. The above drawing shows the cutter form in

relation to the various nished gear pro les.

Thread Milling Cutters

A thread milling cutter is a rotary cutter with one or more convolutions or rows of teeth around the periphery of

the cutter. They are used for milling threads or thread dies of almost any form. They can be designed to mill any

of the standard thread forms, and can also be designed to mill virtually any type of special thread form.

In the operation of thread milling, the lead is imparted into the work by the axial advance between the cutter

and the work during the cut. Thread milling cutters can be made as single, duplex or multiple thread. Single

milling cutters are usually set to the lead angle of the thread and centered on the axis of swivel. They cut one

thread space at a time. For cutting more than one thread on a part, an accurate method of indexing from thread

to thread must be available. Duplex cutters cut two thread spaces at one time. They are also, in most cases, set to

the lead angle of the thread with the tooth space centered on the axis of swivel. They will nish a double thread

in one cut.

Multiple thread milling cutters are set parallel to the work axis, and cut the complete thread on the work in onerevolution of the work with the cutter at full depth. The length of the multiple thread milling cutter must be at

least equal to the length of the threaded portion of the work. The high production rate possible with multiple

thread milling cutters favors their use over single and duplex cutters for most applications. However, there are

length limitations for cutters. Therefore, for long screws, single and duplex cutters are used.

Thread milling cutters are form relieved, can be made with either a ground or unground tooth form and can

be provided with either straight or helical gashes. Multiple thread milling cutters can be manufactured to four

different classi cations. These classes are:

Form Relieved Saw Milling Cutters

Form relieved milling cutters for milling saw blades have special design features which improve the quality of

saw blade point accuracy, and reduce production costs. Gleason Cutting Tools Corp can provide milling cutters

for hack saw, band saw, reciprocating, or circular saw blades. Cutters can be made with straight or helical utes,

and with radial, positive, or negative rake offset sharpening. Tapered O.D. cutters can be furnished for saw

blades that require a positive hook angle on the blade teeth. Interlocking gangs of cutters can be developed to

cut long lengths of hack saw blade.

The alternate cutting of every other ute of the cutter creates the sharp point on the saw blade tooth. Since all

saw blade teeth must be the same height so that each tooth will cut its share of the load, it is critical that the

cutter produce consistent cross-over point heights. The relative axial and radial positions of the milling cutter

tooth cross-over points are held accurately from ute to ute. In addition, the cutter axial and radial runout is

accurately maintained. Accurate resharpening of the cutter will insure that the point-height accuracy of the blade

will be milled consistently throughout the life of the cutter.
