Chip Breaker Design Theory And Practice

The Present Tendency Towards Machining At High Cutting Speeds Has Increased The Demand On The Use Of Chip Breakers And It Has Become Necessary To Ascertain In Advance How A Chip Breaker Will Perform Under A Given Set Up Machining Conditions. This Has Initiated A Number Of Studies On The Mechanism Of Chip Breaking In Machining With Both Obstruction And Groove Type Chip Breakers And Has Prompted Researchers To Formulate Different Breakability Criteria Which Can Be To Evaluate The Performance Of These Devices. The Present Text Analyses The Problem Of Chip Breaking While Machining With A Step-type Chip Breaker Using The Rigid-plastic Slip Line Field Theory.
