need help please

[joey1117]

i have a part that i need to make for a hobby and i would like to do it on my new cnc (emco5) BUT i can not get it to do what i need it to so i thought after i have spent the last 9 hours working on this ( i can run it on a manual lathe in 10 minutes ) i would turn here and see if i can get a little help.
the part is .375 dia and i need to face then turn a dia to .2505.thats it but i need to make 4 of them so i would like it to be able to start in the same spot each time.i have been drawing it in autocad and trying to progam it in mastercam9 all day.i was wanting to know if someone had sometime if they could draw it and set the tool path i will post it here or if you have a good post for the emco5 thats great too.just looking to see what im doing wrong
thanks alot(i would be happy to pay for the time it takes as long as it does not take as long as i have in it )

This is cut with a .5 endmill, you may have to adjust feed and speed, because I dont know what material or machine. Im not sure how deep to go also so you may have to adjust cut depth. Im also using ware comp. so just use a 0.000 value in Cutter comp.

It sounds like it could be a toolnose vector problem.
Are you using tool compensation on this ?

[joey1117]

nope no tool comp at all dont understand why it wont work any thoughts on how to manualy program a .375 dia rod turn down to .2505 dia. .250 back where is zero and what would the code be
thanks
joe

[BMackinnon]

I could write your simple program for you but I have never worked with that kind of controller that uses that code. I am not familiar with it at all.

Maybe if you post what kind of control you have someone else on here can help you, as it is a simple program.

[joey1117]

well the conrtroller is built into the emco lathe ,thats why i am using the mastercam to program with.it is an emco cnc 5 lathe the post above is what it looks like when ran on the cnc itself
thanks
joe
