• What machine reference zero and part zero are.

• What “Home Search” is.

• What travel limits are.

• How to preset a part zero.

• Which are the programming units.

800T CNC1.1 Machine Axes.

Z axis: Along the machine.X axis: Across the machine.


800T CNC

1.2 Machine reference zero and part zero.They are the references the machine needs in order to work:

– Machine ref. zero (OM): Is set by the manufacturer and it is the origin pointfor the axes.

– Part zero (OP): Is set by the operator. It is the part’s origin or datum pointwith respect to which the movements are programmed. It could be setanywhere on the part.

Home


800T CNC

When the CNC is off, the axes may be moved by hand or by accident.

In these situations, the CNC no longer keeps track of the real position of the axes. That iswhy a “Home Search” should be carried out on power-up.

When searching home, the axes move to the home point set by the manufacturer and theCNC assumes the value of the coordinates set by the manufacturer for that point. Whensearching home, the part zero is lost.

HomeHome

Real X

Real Z

1.3 Home Search.

– Home: Set by the manufacturer. It is the point where the axes move during “HomeSearch”.

– Turret Ref.: Set by the manufacturer. Point moving with the turret. It is the pointthat moves during “Home Search”.

Turrent Ref.


800T CNC1.4 Travel limits.There are two types of limits:

– Hard limits: Mechanical limits set on the machine to prevent the carriagefrom moving beyond the ways.

– Software limits: Software limits set at the CNC by the manufacturer toprevent the carriage from running into the machine’s hard limits.

Hard limitsSoftware limitsHome


800T CNC1.5 Part zero preset.It is easier to program movements from a part zero.

The part zero is only set on the Z axis.

OM: Machine Ref. zero.

OP: Part zero.


800T CNC1.6 Programming units.The movement units of the CNC can be millimeters or inches.

millimeters inches

The X axis movements may also be programmed in radius or in diameter.

Radius Diameter

A X=0 Z=0 X=0 Z=0

B X=12 Z=-12 X=24 Z=-12

C X=12 Z=-42 X=24 Z=-42

D X=22 Z=-52 X=44 Z=-52


800T CNC

It could be defined in two ways:

CSS: Constant Surface Speed.

N1=N2V1>V2

V1=V2N1<N2

1.7 Spindle speed.

RPM: Revolutions per minute.

The CNC maintains the cutting speed (V)constant while varying the turning speed (N).

The CNC maintains the turning speed (N)constant while varying the cutting speed (V).

The CNC offers two ways to operate with the spindle:

–Cutting speed (V):It is the linear speed between the part and the tool at thecontact point.

–Turning speed (N):It is the angular speed of the part.

The relationship between them is: V=2*π*R*N/1000


800T CNC

To work at CSS, two things must be borne in mind:

The part zero must be at the part’s turningaxis so that the calculated turning speed is thesame as the best cutting speed.

The maximum turning speed must beprogrammed because the turning speed increasesas the diameter decreases and a particular speedshould not be exceeded on parts with a largediameter.

The CNC works at Constant Surface Speed(Vc) and, starting at diameter Dc (whenN=Nmax), it works at constant turning speed(N).


800T CNC1.8 Axis feedrate.The feedrate of the axes can be programmed in two ways:

– mm/rev: The axis feedrate changes depending on spindle speed. If thespindle is stopped, the axes do not move.

– mm/min: The axis feedrate is independent of the spindle speed. The axesmove even when the spindle is stopped.

NOTEIt is recommended to work at Constant Surface Speed (CSS) and with thefeedrate in mm/rev. This way, the tool lasts longer and the resulting part finish isbetter.

2.- Theory on tools


800T CNC


• What the tool turret is.

• What the tool table is and what information it contains.

• What tool presetting is.

• Defects due to errors in the tool table.

> Due to wrong tool calibration.

> Due to wrong tool location codes (tool shapes).

> Due to wrong tool radius values.


800T CNC

2.1 The tool turret.The tools this CNC can use are placed on the tool turret. This turret may have

either a manual or automatic tool changer. When manual, the tool change is carriedout like on a conventional machine. When automatic, all the tools will be placed onthe turret and the CNC will rotate the whole turret to put the tool at the workposition.

Turret with manual tool change Turret with automatic tool changer


800T CNC

2.2 Tool table.The tool table contains tool information such as their position on the turret,

dimensions, etc.

When changing the tool, the CNC takes this tool information.

The information kept in the tool table refers to: T, X, Z, F, R, I, K:

T: Tool number.

X: Tool length (in radius) along the X axis

Z: Tool length along the Z axis.

Tool Ref.


800T CNC

R: Tool radius. I: Tool wear along the X axis.

K: Tool wear along the Z axis.


800T CNC

Once the tool dimensions are known;

The CNC must know which is the calibrationpoint for that tool (location code) to compensate forthe shaded area (radius compensation).

The location code depends on the orientation ofthe machine axes.

F: Location code or tool shape as it has been calibrated.

800T CNC6.1 Conversational part-programs.6.1.1 What is a conversational part-program?

It is a set of operations ordered secuentially. Each operation is defined separately (alwaysin “automatic” mode) and they are then stored one after the other in a program. Up to 20operations.

The name of the part-program can be any integer between 00000 and 99990.

Besides these, the number 99996 corresponds to a part-program written in CNClanguage, ISO code (Section 6.2 in this manual).

The CNC can store up to 10 part-programs. The rest of them must be stored at a PC.
