Part Profile CNC Code
In this video I demonstrate how to add the code to cut the right side part profile and create the finish tool path. Calculating the proper feed rate and switching between absolute and incremental coordinates will be discussed next. The plunge rate of 25 in/min., is not calculated, but rather just a feed rate I am comfortable letting the machine feed down through the air at.
00:00 Intro
00:10 Recap of the code to this point
00:29 Position cutter at depth
01:16 Arc on, G02 clockwise circular interpolation
02:16 Simulate code
02:42 G03, counter clockwise circular interpolation
03:16 Calculating cutter path radius
03:51 G01, linear interpolation
04:26 Final part G03
04:58 Arc off the part
05:20 End of tool coding
