In chapter 1 lesson 5, we get into workholding and fixturing, and how they play a critical role in whether your parts succeed or fail.

We’ll explore how parts are secured inside a CNC machine using vises, soft jaws, and fixtures, and why stability is essential for maintaining tolerance, preventing chatter, and avoiding tool breakage. From there, we’ll break down different types of vises, how multi axis setups affect fixturing, and what happens when you need to machine every side of a part. We’ll also cover design considerations like no cut zones, part orientation, and how fixturing decisions can impact cost.

What you’ll learn in this episode:

• Why secure workholding is critical for part quality and accuracy
• Common fixturing methods including vises, soft jaws, and fixtures
• How part movement affects tolerance, finish, and tool life
• Key design considerations for clamping and accessibility
