Lessons from Yesterday -

• Control and adjust material properties
  • Alloy, Temper (heat treat), Reinforcement Geometry and Density
• Optimize Casting, Molding Functions
  • Near Net Shape, Minimize Porosity, Control Homogeneity
• Optimize Machining Parameters
  • Maximize chip thickness to maximize tool life per mm3 (in3) metal removed.
• Use diamond tooling for abrasion resistance

Conventional Wisdom - MMCs are Too Expensive to Machine, Primarily Due to the Cost of PCD Tooling.

Notes:

• These are “Engineered Materials”. Engineer them. Maximize your potential for success by considering, up front, the variables that are at you disposal.
  • Adjust the constituents to give the mechanical properties required, that also allow the best chance to machine successfully.
  • Consistency in the mix will also help in the machining process. Don’t want to run in to a high concentration of ceramic all of a sudden.
  • Heat treat does effect, as mention above.
  • Porosity is an issue

• Use the tools at your disposal to get the most from the material.
