Machining Tips for Mold & Die Shops

A smarter approach to machining chase pockets

Have you ever struggled to consistently achieve straight walls and accurate sizing when machining mold insert chase pockets?

This video quickly outlines a solid approach to roughing, semi-finishing, and finishing the walls and floor of a deep, straight-walled pocket, with an eye toward helping you cut cycle times and reduce costly zero cuts. A few key takeaways:

  • High-feed ramping is the fastest way to rough out a chase pocket, but strong air blast is very important.
  • Make sure you leave the right amount of stock for the semi-finishing and finish cuts.
  • The proper tooling, parameters and tool path make all the difference when trying to reduce deflection and execute straight, consistent semi-finish and finish cuts.
  • Create the best possible surface finishes by tackling the floor separately from the walls.

Milling application and demo videos

High-efficiency milling vs. high-feed ramping

Dynamic milling with a solid carbide end mill is all the rage, but you may be able to match – or beat – those removal rates and save significant money on tooling by ramping with indexable high-feed tooling.

Forget time-consuming starter holes and step cuts. High-feed helixing can shorten cycle times for large-diameter hole making to never-before-seen levels – even on a 40-taper machine.

3D milling tips

Tips for more efficient 3D milling

3D milling involves a variety of tools and tool paths. In less than 5 minutes, this video demonstrates three different 3D shapes, what tools we recommend for machining, suggested for path generation for each.

If you’re milling at less than 50% of your cutting tool diameter, you can minimize your cycle time – and maximize productivity – by properly adjusting your programmed feed per tooth.
