Setup a tool with no offset on the Z axis. This will be your "Zero-set" tool. (i.e.Z axis tool offset length = 0.00)
Move the "Zero-Set" tool into a known position on the job, i.e. front face of the part.
Select the "Zero-Set" page.
Move the cursor to highlight the Z axis.
Press the soft key "CAL" (Calculate) and enter the Z axis position required, then press the "WRITE" key.
CHECK THAT YOUR Z AXIS POSITION IS SHOWING THE ENTERED POSITION, on any of the AUTO/MDI/MANUAL screens.
Good to go!
Setting TOOL Data:
1. Move the selected tool into a known position. i.e. after Zero setting the machine, touch the tool against a know face position (for Z)
2. Select the Tool Data screen.
3. Move cursor to the desired tool number and highlight Z axis (in this example).
4. Press "F8" (Extend) and then "F3" (CAL).
5. Enter the position of the face, then press the "WRITE" key.
The process is the same for setting X axis, measure a diameter, touch your desired tool to the diameter, CAL the diameter.
Good to go for tools.
I have always used Tool 1 for my Z-Axis ZERO Set tool, as this is my facing tool, but any tool can be used, just make sure all your tool lengths are referenced from the selected "Zero" tool.
As for X axis, I have always Zero-set X0 as being the centreline of a Drill/Boring Bar holder.
Touch off your ID Tools from the known ID and "CAL" the tool offset.
Hope this helps.
