Design Principles

"Material deformation during subtractive manufacturing is a function of cutting parameters and tool geometry, and can be controlled to achieve desired tolerances."

In manufacturing processes involving OFHC copper, such as in electronics or specialized components, excessive deformation during cutting can lead to defects, reduced performance, and increased scrap rates. Designers and manufacturing engineers need to select appropriate cutting speeds, feed rates, and tooling to mitigate these issues.

What This Means for Your Design

When cutting copper, changing how fast you cut, how much material you take off at once, and the shape of your cutting tool can change how much the copper gets bent or misshapen.

How to use in your project

  • 1.Reference this study when discussing the manufacturing processes for metallic components and the potential for material deformation.
  • 2.Use the findings to justify your choice of cutting parameters or to explain observed issues in your own design project.
