Re: [Emc-users] G2, G3 Arc Feed with rotaty axis

Thanks a lot Andy and Chris! Very well explained, and it's easier than what I was thinking. Andy as Peter well said, this is to make a positioning system to do induction heating on crankshafts. Since all the journals need to be heated, and we're planning on making a production of at least 100 pie

Andy, from what I know from Leonardo, I druther guess that it's a case of zonal induction heating for hardening purposes. Peter Am 05.03.2013 20:35, schrieb andy pugh: > On 5 March 2013 19:34, andy pugh wrote: > >> G2 X0 Y0 C720 I10 J10 F10 P2 >> >> Is what you would need. > I guess you are mea

Hello Andy. Now the machine is turned on and working but when I have a little time I will try with that configuration. The program line would be more or less like this right? (movement on X and Y, C is the rotary axis) G2 X0 Y0 C360 I10 J10 F10 P2 Would that give a two turn movement on the rota
