Programming a Part on a CNC Lathe using G Code: Step 1: Planning

In this new series from GCodeTutor, Marc will write a program to make a part on a CNC lathe using G-code.

This video is all about planning how we are going to make the part. With a solid plan in place, it is much easier and quicker to write the program.
We start by examining the working drawing, identifying any missing dimensions and solving the math to determine all the points needed to plot the profile in our program.
We also consider the correct order of operations, using best practices to machine each feature in a logical manner.
Finally, we select the appropriate tooling for each operation.
Once we have thoroughly analyzed the working drawing and determined the machining sequence, only then can we start programming our part.
