Metal Cutting: Fixturing Fundamentals for Machining

Fixturing Fundamentals for Machining introduces learners to the basic equipment, concepts, and general terminology that are often applied for fixturing or workholding. The important and yet sometimes overlooked process of metal part fixturing is brought to life in this course using realistic 3D models of actual parts. Helpful animations are also provided for concepts such as the 3-2-1 Principle and how to arrest the 12 degrees of freedom. The material in this course is beneficial to both experienced fixturing or workholding veterans and to learners new to the industry.

Learning Objectives

  • Recall the 3-2-1 Principle and the 12 degrees of freedom.
  • Recognize basic fixturing components such as pads, clamps, and baseplates.
  • Identify the common machining centers and how each relates to fixturing.
  • Understand the cutting forces involved in common machining operations.
  • Differentiate between the various datums applied in fixturing.
  • Recognize basic concepts such as averaging and locator application.
