⚙Factors Affecting the Machinability of AMS 5639 Flat Bar

Work Hardening

Surface toughens fast under cutting load, resisting the next pass.

Heat Generation

Low thermal conductivity traps heat right at the cutting edge.

Tool Wear

Abrasive, tough chips shorten insert and tool life quickly.

Built-up Edge

Sticky chips weld onto the tool tip, spoiling surface finish.
