Work Zero defines the work coordinate (part or stock) origin. This is typically done after MCS orientation is defined under Setup. Work Zero translates the MCS origin from the Setup to the desired location. This can be set to any location on the part or stock geometry.
Refer to CSYS Setup for orienting the Machine Coordinate System.
This dialog can be invoked by selecting Work Zero from Program tab under the Machining Browser.  Machining Browser: Work Zero menu item - Premium Configuration shown |
Set Work Zero dialog appears as shown below. You can set the origin by explicitly picking a point or can set it with respect to the Part or Stock geometry bounding boxes.  Dialog Box: Work Zero |
If you select the Pick option, the button
|
You can use object snaps located in Selecting this item will activate the Zero Face and the Zero Position sections of the dialog. You can then select the Z and the XY locations, with respect to the bounding box of the stock geometry, by choosing the appropriate selections in the dialog. |
Similar to the previous selection, selecting this item will activate the Zero Face and the Zero Position sections of the dialog. You can then select the Z and the XY locations, with respect to the bounding box of the stock geometry, by choosing the appropriate selections in the dialog. Selecting Ignore Wireframe Geometry in Bounds Computation ignores all 2D and 3D curve geometries present in the part for bounding box computation. |
This allows you to specify a Work Coordinate Offset number which is then output in the posted code. This is set under Work Offset Register Number. Work offsets are used to set work piece origin(s) on CNC machines that are assigned to a register number G54, G55 etc... Entering a positive number will make incremental offsets positive (i.e., G54, G55, etc.) Entering a negative number will make decremental offsets (i.e., G54, G53, etc.).
For example: •To output G54, G55, etc., set the Work Offset Register number to 54. To output G54, G53, etc., set the Work Offset Register number to -54 (negative). •The Work Offset Prefix “G” is set in the post-processor generator. |
Click Generate and Work Zero is now listed under Setup in Machining Browser. The MCS origin is now translated to the specified location.  Work Zero displayed in the Machining Browser - Premium Configuration shown |
In the example shown below Work Zero is set to •Set to Stock Box •Zero Face – Highest Z •Zero Position – South West
