    Default Conquest T42: How do you program a sub-spindle transfer?

    I tried the example for transferring a part from the sub-spindle to the main spindle as shown in the Hardinge Conquest T42 Programmer's on page 16-19. In this example, it uses the G10 P0 command to modify the workshift for both Z (turret) and Y (subspindle), as follows:

    G10 P0 Z-1.75
    G10 P0 Y-1.75

    After trying this, the Z workshift offset is modified, but the Y workshift offset is NOT.

    And get this... I called Hardinge and spoke with Bob Allington who himself tried this out on one of their machines and got the same result! So it's not my machine, after all.

    So, if the manual is wrong, what is the best way to transfer a part from the sub-spindle to the main spindle?

    Put another way, how do YOU do it? What have you established as the best practice for this operation? Do you use G54, G55 for main/sub? Do you program in absolute values? Can you provide an example of gcode that you actually use in production?

    You should have this as a sub program here it is for a ball screw T42 sub spindle full program below go slow to test it and have a special cut off (if bar work that will fit between both spindles)
