MC015: CAM Tips and Dynamic Machining with Matt Sump [Podcast]

By March 21, 2015 VIP Guests

What are the 3 most important actions that manufacturers can take now to improve their utilization of Computer-Aided Manufacturing?  In this episode, we interview Matt Sump with ShopWare to discuss CAM Software and Dynamic Machining.  Jim answers the question: If you put 10 machinist in a shop and gave them a piece of material and a print, how many different ways will they produce that part?

We discuss:

  • Latest trends in CAM software
  • How tool paths are calculated
  • Radial chip thinning
  • Most efficient amount of material removal
  • Spindle speed
  • Utilizing a tooling database in CAM software
  • Machine utilization
  • Dynamic Machining versus High Speed Machining
  • Improving machining hydraulic manifolds using CAM software
  • Utilizing Dynamic Tool Paths
  • Automating existing processes with macros
  • Going beyond the basics by automating

We briefly talk about the history of how MakingChips was started.

In our Manufacturing News segment, we discuss an article declaring that US manufacturing is going extinct.  I’m going to state it here: if you remove manufacturing from the US Economy, the United States will lose 30% of its GDP.

    Just listened to the episode. Awesome Podcast guys!

    Just wanted to point out something about your MasterCam conversion. What you guys were talking about with tooling libraries and full flute cutting and optimal cutting paths. A Hurco mill can do all of this at the machine and has been able to for some time now. You don’t need mastercam to do this. In fact I’d bet you guys lunch that I could have a mill running the part before your Mastercam guy could get a program posted!

    Great show, keep it up!

    Universal tooling data libraries are in the works across all major vendors. The ISO 13399 standard codifies information about cutting tools and allows CAM or any other software to consume this data without additional translation. It’s sort of similar to the way HTML can be consumed by multiple browsers to still show the same webpage.

    I hope these concepts continue to gain traction. Understanding this stuff will never supplant machining knowledge, but failing to embrace new technology and techniques leaves money on the table even if a company totally “gets” metalworking.
