In this Office Hours, Jake breaks down what actually controls how fast you can machine a part. We’ll look at the relationship between RPM, feed rate, and chip load, and how changing one affects the others.
In this episode you will learn how to:
• Understand the relationship between RPM, feed rate, and chip load
• Maintain the right chip load when changing machining speeds
• Recognize what happens when an end mill takes too much or too little material
• Understand how machining speed affects tool life
• Determine what actually limits how fast a CNC machine can run
When it comes to CNC machining, running faster isn’t as simple as turning up the RPM. It’s about finding the right balance for the tool, machine, material, and part you’re making.
