How To Optimize Your Lathe Application

Insert deliver optimun performance when they fail trough normal flank wear, If some undesirable failure mode is dominant, your aplication can probably be improved by changing the grade, chipbreaker geometry, or cutting parameters until failure through normal flank wear is archieved.

The optimization charts on pages 30& 31 show correc chip formation and common failure modes. on different types workpiece materials.

The two best indicators of an optimum turning system are properly formed chips, and predictable insert failure by desied mode for your workpiece material. Use thes chart to check on your progress toward an optimized turning system and stay in touch with your Valenite representative for news of the latest technical innovations.

MATERIALS		CHIPS		PREDOMINANT FAILURE MODE(S)

Steels	Low Carbon		Built up Edge
Steels	Mild & Alloys		Rapid Flank Wear & Cratering

Stainless Steels	300 Series		Build up Edge & rapid Flank Wear
Stainless Steels	400 series		Rapid Flank Wear

High Temp Alloys	Nickel Based		Build up Edge& Chipping
	Titanium Based		Build up Edge& Chipping
	Iron Based		Build up Edge& Chipping

Irons	Gray		Rapid Flank Wear & Cratering
	Ductile		Built up Edge & Rapid Flank Wear

PROBLEM/FAILURE MODE	CAUSE	CONTROL ACTION / REMEDY	PROBLEM/FAILURE MODE	CAUSE	CONTROL ACTION / REMEDY
	Excesive Cutting Speed Work Material Microstructure Contains Carbides	Reduce Cutting Speed Use Harder Grade Positive Rake Chipbreaker Flood Cutting Zone w/Coolant		Improper Selection of Grade / Chipbreaker and/or Cutting Conditions	Reduce Feed Rate Select Tougher Grade Select Stronger Chipbreaker Make Sure Set Up is as Rigid as Possible
	Excesive Cutting Speed Ineffective Use of Coolant	Reduce Cutting Speed & feed Select Harder Grade w/Occide Coating select More Positive Rake Chipbreaker Flood Cutting Zone w/Coolant		Extreme Variation in Cutting Temperatures Interrupted Cut	Reduce Feed Rate Incresase Cutting Speed Select Stronger Chipbreaker
	Low Cutting Speed Low Feed Rate Poor Shearing Action	Increase Cutting Speed Select More Positive Rake Chipbreaker Select Tougher Grade (Use PVD Coolant Insert) Flood Cutting Zone w/Coolant		High Feed Rate Low Cutting Speed Nose Radius Too Small	Reduce Feed Rate Increase Cutting Speed Select More Positive Rake Chipbreaker Flood Cutting Zone w / Coolant Use Larger Nose Radius
	Excesive Feed Rate Interrupted Cut	Reduce Feed Rate Select Tougher Grade Select Stronger Chipbreaker Increase Lead Angle		Poor Set up Impproper Insert Selection	Use Sharp Inserts Selection MOre Positive Rake Chipbreakers Increase Lead Angle Use Smaller Nose Radius
	Scale Part High Work Hardening Materials	Increase Lead Angle Increase Cutting Speed Select Tougher Grade Select Stronger Chipbreaker Vary Deph of Cut if Possible		Low Feed Rate Large Nose RAdius	Increase Feed Rate Select Smaller Nose Radius Decrease Lead Angle
