    Question Programming a flat with live tooling and c axis on a lathe

    I have a Hitachi seiki lathe with live tooling and a c axis I have seen flats being milled before by rotating c axis while moving in x axis similtaineously but I have never programmed one to do it. Does anyone know how to do this?

    I do it with one of my CAM programs. There should be info on how to do it in your machine manuals with the formulas.

    if you have the multi seiko's control there should be a built in macro for it.its been 10+ years since I played with one. the only one I played with was the Mutil controls, never played with the other controls for the mill turn. those are fun machines.

    Default G112 POLOR MILLING

    G112 Polor milling is what Ive used. G112 when called in a program converts c axis movement to y just like programming a mill in x,y olny differance is you program x as dia. and y as radious. There is no y axis actually on the machine keep in mind it just changes the cordanent system from c to y...hope this helps....
