CrankshaftMaster Exercise Presentation

85 min

In this exercise, you will learn Lathe Machining fundamental concepts by machining a Structure Part from the 3D.

This process includes the creation of the Part Operation and all necessary machining operations and auxiliary operations. You will also generate the NC code and manage associativity when the design part is modified.

Master Exercise is split in 7 steps. The end result of one step is the start for the next step. Respective Master Exercise Step will have to be performed after completion of each lesson.
