Hello,
I need to program an external axial thread mill, (see attached drawing) its an M10 x 1.5 thread, 19.5mm long
I'm using a Doosan lynx 220lsy, with fanuc Oi control.

Here is the program I have come up with so far, for the milling & thread milling, could you have a look & see what you think, thread milling is new to me so any help appreciated

Got this program sorted, for reference here is the successful program, in case anyone searches for similar. Could'nt get polar coords to work properly for the spud, so just used x & y
