Work Zero

Once the Stock is defined you can then define where on the Stock (or on the Part) that you want to locate the program zero point. The point selected should be the actual location on the stock or part where you will physically tell the CNC Machine Tool to be its program coordinate zero point.  Once created, the MCS triad is displayed at this location.  

Note that the Face and Position options on the Work Zero dialog (shown below) will refer to the current orientation of the Machine Coordinate System (MCS) as defined by the Machine dialog.

1.Select Work Zero from the Mill toolbar or double-click left-mouse-click Work Zero under the Machining Job.

Name

You can give the Work Zero a unique Name that will appear in the Machining Job.

Type

There are two Types to choose from:

Set to Stock Box

The Face and Position selections will locate the Work Zero relative to the extents of the Stock Box.

Set to Part Box

The Face and Position selections will locate the Work Zero relative to the extents of the Part Box.

Origin

First select Pick from the Type section of this dialog and then enter the XYZ coordinate values to locate the Work Zero.

Face

This defines the Z level for the Work Zero.  The options provided are relative to either the Stock Box or the Part Box, depending on which Type you selected from the dialog.  Select Highest Z, Middle Z or Lowest Z.

Position

This defines the XY location for the Work Zero.  The options provided are relative to either the Stock Box or the Part Box, depending on which Type you selected from the dialog.  The cardinal directions are relative to part views (i.e., North equals Back, South equals Front, East equals Right and West equals Left).

Work Offset

This allows you to specify a Work Coordinate Offset number which is then output in the posted code. Work offsets are used to set work piece origin on CNC machines and is assigned to a register number G54, G55 etc...

For example:

To output G54, set the Work Offset Register Number to 54.

The Work Offset Prefix “G” is set in the post processor generator.

3.Pick Save and your Work Zero will be updated under the Machining Job.
