Cylindrical interpolation

[davisboys]

I've turned on the option for cylindrical interpolation for a five axis Citizen with Fanuc 18 control. Supposedly this machine is capable of this cycle. It's not working yet. Anyone know any tips or tricks for getting the G107 option going?

what cam system are you using, mastercam X etc? you need to go to mis values when you are setting up the tool parameter and set it to either -1 or 1. G107 has be in a line by itself and just before the tool is going to engage the work. I was having struggles with this and recieved some great help in the Mastercam forum. I also had to edit my post so that everything was do in the proper order. This was a trial and error at the machine and when I got the correct i modified my post to give me the correct output. You can also try the machine maker and ask for a sample program that they would use at say Westec and see what it is. Hope this helps. my 2 cents

We are using Partmaker, (no forum for it yet as far as I can see) but it must be similar. We will go to the machine maker and ask for a sample program (a template I like to call it). Great suggestion! As it turns out, Eastec is a month away. Maybe those exhibitors will be feeling helpful....

the 2 cam systems are probably similiar so just have a cruise thru yours'. i learned a lot of new swear words trying get the polar and cylindrical interpolation to work. best of luck at Eastec. enjoy the day, mine has just started

anyone can say the macro variable no for current tool in spindle?

[dcoupar]

What machine? What control? What does this have to do with cylindrical interpolation?
