The Student will create 5-Axis milling toolpaths
consisting of:
!Create a Impeller floor surface without tiltcurve toolpath from the Custom Application
toolpath family to rough the area between two blades.
!Switch to the Advanced interface and create a Morph between 2 surfaces toolpath to
add depth cuts and avoid gouging the blades.
!Finish the impeller floor using the same Morph between 2 surfaces toolpath.
!Create an Impeller blade swarf finish toolpaths from the Custom Application toolpath to
semifinish one blade.
!Switch to the advance interface and create a Parallel to surface toolpath to add multipasses
the toolpath.
!Create a Parallel to multiple curves toolpath from the Wireframe toolpath family to finish
the blade.
!Create Transform Rotate toolpaths to machine the entire impeller.
The Student will simulate the toolpaths using Mastercam's Verify and Backplot by:
!Defining a 3-dimensional shape the size of the work piece.
!Running the Backplot to see the path the tool takes to cut the part.
!Running the Verify to simulate the tool cutting from the solid model.
!Running the Machine simulation to detect collisions between the stock, tool and any
machine components.
This tutorial takes approximately two hours to complete.

TUTORIAL #41 SELECT THE GEOMETRY FILE
This tutorial covers Mastercam's 5-Axis toolpath functionality. To apply these toolpaths to a 5-Axis
machine tool, a customized post processor for your machine is required.
There are no default 5-Axis post processors included with Mastercam due to the variation in multi-axis
machine configurations. Contact your Mastercam reseller to request post processor services such as
multi-axis post development.
Your post processor may require certain additional programming information not covered in this
tutorial. For instance:
You may be required to position your stock in machine space rather than at Mastercam's origin.
You may be required to use the Misc Values.
Your post may also prompt you for tool gage lengths.
The nature of the additional information required depends largely on your machine's configuration.
Contact the developer of your post processor for details.
STEP 1: SELECT THE GEOMETRY FILE
Resources - Download the file from www.emastercam.com/files

SELECT THE MACHINE AND SET UP THE STOCK TUTORIAL #41
STEP 2: SELECT THE MACHINE AND SET UP THE STOCK
In Mastercam, you select a Machine Definition before creating any toolpaths. The Machine Definition is
a model of your machine tool's capabilities and features and acts like a template for setting up
machining jobs. The machine definition ties together three main components: the schematic model of
your machine tool’s components, the control definition that models your control unit’s capabilities and
the post processor that will generate the required machine code (G-code). For the purpose of this
tutorial, we will be using the 5 - AXIS TABLE - HEAD VERTICAL machine.

Backplotting shows the path the tools take to cut the part. This display lets you spot errors in the
program before you machine the part. As you backplot toolpaths, Mastercam displays the current X, Y,
and Z coordinates in the lower left corner of the screen.
Make sure that the toolpath is selected (signified by the green check mark on the folder
icon).
Backplot the toolpath
Select the Backplot selected operations button.
Make sure that you have the following buttons turned on to see the tool and the rapid
moves.
To be able to easier check the toolpath, click on the Options button.

Select the OK button to exit
Backplot.
Press Alt + T to remove the
toolpath display.
NOTE: This toolpath is only a finish operation. To add depth cuts for a roughing operation
we need to switch to the advanced interface.
The advanced interface will allow us to use margins which will shift the tool to avoid
gouging.
To rotate the part, to visualize the toolpath better, move the cursor close to the middle of
the surfaces and holding down the mouse wheel, move the cursor slightly to the left until
the geometry looks as shown.
Page|4-16 Advanced Multiaxis Training Tutorial
TUTORIAL #41 MORPH BETWEEN 2 SURFACES
STEP 5: MORPH BETWEEN 2 SURFACES
Morph between 2 surfaces toolpaths creates a morphed toolpath on the drive surfaces. The drive
surface is enclosed by two check surfaces. A "morphed" toolpath is one that is approximated between
the check surfaces and evenly spread over the drive surface. This toolpath pattern is especially useful
during impeller machining with twisted turbine blades.
The main advantage is the possibility to compensate the tool to the drive surface and check surface in
the left and right corner of the workpiece. All you need to do is set the margin, or distance between the
tool center and the surfaces, equal to the tool radius.
Toolpath Preview:
5.1 Rough out the area between two blades using Morph between 2 surfaces
Select the Parameters in the 5AxMSurf operation.
From the Tree View area select Misc and click on Switch to advanced interface button.
NOTE: Mastercam switches automatically to the Morph between2 surfaces.
Advanced Multiaxis Training Tutorial Page|4-17
MORPH BETWEEN 2 SURFACES TUTORIAL #41
5.2 Add the margins to avoid tool gouging into the blades
Change the following parameter:
Start/end margin = 0.2.
Additional margin to overcome surface edge inaccuracies = 0.0018.
Margins
Margins create additional space so the toolpath is not starting directly on the surface edge.
Additional margin to overcome surface edge inaccuracies is a value added to the edge curve tolerance.
Surface edges and edge curves are not exact matches due to tolerances. Use this value to eliminate any
toolpath calculation issues where ragged edges are encountered.
From the Tree View area, expand Cut Pattern and select Margins.
Change both the Start margins and the End margins to 0.2.
Leave the Additional margin to overcome surface edge inaccuracies set to 0.00118.
Select the OK button to exit Multiaxis Toolpath - Morph between 2 surfaces.
5.3 Regenerate the toolpath
From the Toolpaths Operations Manager, select the Regenerate all selected operations.
NOTE: To leave some stock on the check surfaces we can give as Start /End margins a value
bigger than the tool radius.

Collision Control
Collision control establishes clearance values and instructs the toolpath how to move the tool to avoid a
collision. A single strategy is usually all that is needed, however you have the ability to set four different
strategies if necessary.
Tilting tool away with max angle avoids the gouge by tilting the tool away from the surface.
Use side tilt angle tilts the tool to the side relative to the cutting direction. Positive angles tilt the tool to
the right, negative to the left. The limits are min. +/-0.01° and max. +/-180°.
From the Tree View area, select Collision Control.

Linking
Linking determines how the tool moves when not cutting material.
First entry is the first approach of the tool towards the part. You can specify from where the tool should
approach (enter) the part and whether there will be a lead-in move when entering the part.
Last exit defines how the tool will leave the part and where it will go after the toolpath is complete.
Gaps along cut options define the tool behavior if gaps are detected along a toolpath.
Links between slice options define the tool movement when stepping between cuts.
Set the First entry/Last exit to use Lead In/Out.

Impeller Blade Swarf Finishing
Impeller Blade Swarf Finishing settings determine the geometry the tool follows and how it travels
along that geometry.
Area type lets you define the area on the drive surface to be machined. You can choose between "full"
which machines the entire drive surfaces, determine by number of cuts or limit the cuts between points.
Sorting allows you to set the cutting method and the direction of the cut.
Cut tolerance is the tolerance for the accuracy of the toolpath. This value is the chordal deviation of the
toolpath against the surfaces to be machined. To generate more points along the cut for better accuracy
you can set the maximum stepover.
Maximum angle step sets the maximum allowed angle change between two consecutive toolpath
positions.
Follow surface iso side tilt definition is a good option if linear surfaces are present. If any surface does
not have a compatible U and V direction with the neighboring surfaces, then this function attempts to
automatically correct these areas.

FINISH THE BLADE SURFACES - PARALLEL TO MULTIPLE CURVES TUTORIAL #41
STEP 9: FINISH THE BLADE SURFACES - PARALLEL TO MULTIPLE CURVES
The Parallel to multiple curves toolpath pattern will align the cut direction with a leading curve.
Adjacent cuts are parallel to each other. It is important to note that the cuts will not simply be copied
next to each other. Every new cut is created at an offset from the previous cut.
The curve must be located exactly on the surface edge, so the best curve would be the edge itself. This is
very important for toolpath generation. If you don't have a proper curve, an incorrect toolpath can be
generated.

FINISH THE BLADE SURFACES - PARALLEL TO MULTIPLE CURVES TUTORIAL #41
Margins
Margins create additional space so the toolpath is not starting directly on the surface edge. Start
margins allows you to enter a positive distance to offset the first pass from the surface edge. The offset
places the tool inside the surface boundary.
From the Tree View area, expand Cut Pattern and select Margins.
Set the Start margins to 0.09493 and leave the
Additional margin to overcome surface edge
inaccuracies set to 0.00118.
Tool Axis Control
Tool axis control settings determine the tool's orientation in relation to the geometry being cut.
Output format set to 5-Axis allows for tool rotation in two planes.
Maximum step angle sets the maximum allowed angle change between two consecutive toolpath
positions.
Be tilted relative to cutting direction allows you to assign a lead/lag angle to the cutting direction and a
tilt angle at the side of the cutting direction.
Ortho to cut dir at each pos side tilt direction is determined by an orthogonal (perpendicular) line from
the current surface contact point to the lower edge curve. That means that the tool axis is always
orthogonal to the toolpath.
From the Tree View area, select Tool Axis Control.
Set the Tool axis will. to Be tilted relative to cutting direction.
Tilt angle at side of cutting direction = 80 degrees.
Side tilt definition set to Ortho to cut dir at each pos.
NOTE: The sum of the two values is the radius
of the tool.
