### COMMON EQUATIONS FOR OPTIMAL PERFORMANCE

2020-8-24  Speed and feed considerations are crucial for optimal results. Incorrect speeds and feeds can cause increased chatter, poor finish, hamper production, chip packing, damage the cutter, etc. Too high of a speed or too light of a feed leads to reduction in tool life. Speed is measured in feet per minute and is referred to as cutting speed, surface ...

### How to Determine Cutting Speeds for Machining

2021-2-26  All cutting tools have a recommended cutting speed for any given material. Softer metals like aluminum and mild steel have higher cutting speeds than do nasty metals like titanium or Inconel. So, too, can carbide and ceramic cutting tools achieve higher speeds — regardless of the workpiece material — than do ones made of high-speed []
