Enter material, tool diameter and flutes to get recommended cutting speed Vc, spindle speed n and feed vf. Results are the mid of empirical ranges — adjust by machine rigidity, insert grade and coolant. For hard materials, start conservative.
Turning holders+inserts, end/ball/corner-radius mills, drills/U-drills, fine boring heads. Choose the family in Products.
Steel: YZ6020; stainless: YZ6030/KT1505; cast iron: wear-grade; aluminum: sharp grade; hard: CBN. See Insert Selection and Stainless Tools.
Set Vc (this calculator), then n and vf by flutes; roughing large ap small ae, finishing small ap. Hard materials: lower Vc, strong coolant.
Start small, watch chip, chatter, finish and wear; ramp up. Free trial and tool-matching via Contact.
