Bob Warfield is a proven CNC expert and is the creator of www.CNCCookbook.com and the very popular G-Wizard Speed and Feed Calculator software. We are thankful for Bob taking the time to discuss his software, speeds and feeds and much more.
Bob discusses how he started CNCCookbook and what led him to starting the G-Wizard Calculator which started around 2007, which he wrote entirely on his own. He designed this software to accomplish three things:
– To be the world’s best speeds and feeds calculator
– Help people remember tips, which are built into the program
– Wanted software that would optimize the numbers
We also discussed using CAD/CAM Wizards to generate a solid starting point for your feeds and speeds when setting up a job by answering a few questions in the wizard and it will give you a complete recipe for performing that CNC operation.
We also discuss tips for cutting aluminum on CNC router machines.
We discuss the effects of rubbing and excessive heat and how it adversely affects how the CNC cuts as well as shortening cutter life.
Chip clearing is very important in a CNC job as well because the heat is extracted from the end mill and material and is carried away in the chips.
We discuss the very popular topic of Climb vs. Conventional cutting.
We discuss using your ear to listen for the best speeds and feeds settings, and how this is not the best way to setup your machine.
We also discuss chatter, what causes it and how do diagnose it.
