CNC Machine Set-up

Procedure for setting up a multi vise operation.

1. Place vises in machine and align the vises straight.  (Use the solid jaw for indicating)
2. Install part stops on all vises to ensure proper placement of parts.
3. Set work offsets for all vises.
4. Load tool 1 and set tool length offset at "Z" zero.
5. Use tool 1 and find the differences in the "Z" heights at each vise.Set up the rest of the tools on the G54 vise.
  - The difference in the vises will be the "Z" value for their work offset.  (G55, G56)
6. Run program and inspect each operation.
Set-up 2 vises and make sure that they are indicated in straight on the table.
Edge find the work offset corner being used for program zero G54 (top side of part).
Press Part Zero Set for both axes in G54.
Find Work Offset for G55 (bottom side of part)and place work stop on work and make sure that it does not interfere with the machining process.

Notice the part stop for the second operation.
Tool 1 is now set in the tool offset page.
Touch the same tool (Tool 1) on the bottom operation of part or the G55 offset and press tool length measure at a different tool length number that is not being used in the program.
