Lesson 1.7

How to Design Parts Using Adaptive and Pocket Toolpaths

This series was filmed and edited by Keaton Bowlby

In chapter 1 lesson 7, we continue building on toolpath strategies by exploring how tool engagement and cutting patterns impact performance, finish, and cost.

We’ll break down the concept of tool engagement and why balancing it is key to avoiding tool breakage while maximizing efficiency. From there, we’ll compare two common roughing strategies, adaptive clearing and pocket clearing, and show how each affects cutting forces, tool life, and machining stability. We’ll also introduce step down and step over, and how adjusting these values changes cutting aggressiveness, surface finish, and machining time.

What you’ll learn in this episode:

  • What tool engagement is and why it matters
  • The difference between adaptive clearing and pocket clearing
  • How cutting strategy affects tool stress and efficiency
  • What step down and step over mean in CNC machining
  • How to balance speed, finish, and tool life
