This is why you need a Y axis

The code is the easy bit the hard bit is getting a machine that can follow the code instructions,  you need the X or Y axis to be in sync with the spindle.  Then the code is generated using Sin and Cos of a selected arc length on a offset centre point, the Z movement is then divided into the number of cords.

If you make the conforming machine I will write you the code.

Clive,

if its a repeat job bore a offset hole in a round billet and split it through the thick side then you can hold it in the three jaw.

You would need a lathe with a Y axis for a start so you could maintain the tool centre height.

Mach3 has no looping macro commands.

Search the forum for G52 command, this allows you to write your sub in absolute and call G52 X? Y? as local datum point. Use G52 X0 Y0 to cancel the shift before you issue the next.

Hi Phillip,

post your code here and hi-light the problem area in the code.

General Mach Discussion / Re: Mach3 with a lathe - 6 axis simultaneous ?

If you are wanting to have the machine rapid one axis and be feeding on another then Mach3 V3****************** can NOT do this yet, to do that you need multi planners, that is for the future.

You can set certain ones with a #number , for example you can set fixture offsets that will update there positions by setting the #2500,2501,2502, for XY&Z on G54.

To zero out the absolute figures you just do a G92 X0 Y0 Z0 or any combination of axis.

Go to the help menu and your name will be shown in the about window if its a licensed version.
