Beyond CAM—CNC Programming for Machining Effectiveness

December 20, 2019

(Part 5 of 9)

There are many ways Mastercam and our partners are harnessing integrated data technology to improve manufacturing performance and profitability. Here we take a look at CNC programming for machining effectiveness.

With a model prepped for programming and a workholding solution designed, it is time to create a part program for the chosen equipment. The goal is to make a good part with a minimal number of setups and to do it as efficiently as possible. Set-up requirements are a function of the number of axes available and the functionality of the workholding solution.

For roughing, maximum machine efficiency is obtained by using Mastercam’s Dynamic Motion™ technology to continuously optimize cutting parameters based on the cutting tool manufacturer’s chip load recommendations for the selected material and the machine’s capabilities. R&D into Dynamic machining approaches is ongoing, with emerging technology focused on substantial improvements in finishing quality and material removal being achieved by pairing advanced cutting tools with Dynamic toolpaths.

Job shop managers tend to look at these things independently. However, when cutting tool performance, CNC cutting strategies, and machine capabilities are optimized in combination, overall savings of 15 to 25 percent are obtained routinely.

For a more detailed overview of this topic, you may refer to the Cutting Tool Engineering article Achieving Machining Effectiveness, by Stas Mylek. []

We will examine the topic of tool management in the next installment of Beyond CAM. Stay tuned!
