Any advices greatly appreciated:
I needs to cut the slot, 60 degree ...... If you look in front of the part, it look like a V from the center of the part. How do we cut that slot with a 4 axis machine Okuma Millac, how do we rotate A axis in mastercamX3, please help me, greatly appreciated.
Post attachments to show what you are wanting to do.
The first part sounds more like a general machining question. You are saying "slot", but it sounds as if you are describing a "V" groove. To cut a 60 degree "V" groove, use a cutting tool with a 60 degree included angle.
To have rotation on the A axis, you have to use a machine definition that has an A axis. Then when setting the parameters of the tool path, check the Rotary axis box and click on the button to set the rotary axis parameters.
