how to post g70 and g71

how do I make mastercam post out the g70, and g71 on a lathe

[Geof]

Why do you want to do this? These canned cycles are not needed when you use a CAM program.

just incase i wanted to edit on the machine

In version 9 it is a separate tool path called canned rough. But your post will have to support it.

Also in mcx, Toolpath--->Canned--->Rough or Finish

[tornero32]

are you using X or V? even if you are using Mastercam you should use them. If you need to change the depth of cut you do it at the control if not you have to go back to Mastercam and re-post.
Go to Toolpaths>>canned>>rouhg.
if you need help adjusting the post I will help you.

Alguen me puede ayudar!! Tengo un clausing colchester cnc-4000 con fanuc OT, En el perfile de un ciclo G71 para desbastar diametro interior, COMO INICIO EL PERFIL;;;;,,,ponle que tengo un diametro perforado a 50mmx100mm y quiero desbastar a diametro 80mmx90mm con radio de 6mm en el fondo,,,,,!! COMO! NO ME RESULTA!!

We are taking about Mastercam, is that what you need help with?
Estamos hablando de Mastercam, ocupas ayuda con eso? o solo quieres programarlo a mano? si es mastercam te puedo hacer un video rapidito, si es a mano el fanuc OT usa dos lineas en el G71.
G71 U... R..
G71 P.. Q.. U.. W.. F.. S..

Linea primera
U significa la profundidad del corte en cada pasada
R significa la distancia que se retira la herraminta en cada pasada

segunda linea
P significa el numero de la linea donde empieza el terminado
Q significa el numero de la linea donde termina el terminado
U significa la cantidad de material que vas a dejar para el terminado en X
W significa la cantidad de material que vas a dejar para el terminado en Z
F significa velocidad de avance
S significa las revoluciones revoluciones

asi que tu programa quedaria asi:

He means Mastercam V (version) 1 through 9, once it changed to 10 then it was X. Nothing to do with the machine.

Yes version V5 To V9, or X to X5, thank you littlerob.
vanfolch did that information that I send help you? or do you still need help with mastercam. I do not have V9, do you have the post for the machine? do you want me to do make a video to show you how to use it?
