What is flank wear, and how does it affect machining performance?

Flank wear occurs on the clearance surface of the insert due to prolonged contact with the workpiece. It can lead to dimensional inaccuracies, affecting the precision and quality of machining operations. It is recommended to monitor the wear closely and select appropriate ISCAR grades to mitigate this issue.

How can crater wear be minimized in high-speed cutting operations?

Crater wear appears on the rake face due to chemical and thermal interactions between the chip and insert material. To minimize this, use ISCAR inserts with advanced coatings and optimized geometries, along with proper coolant management to reduce heat generation.

What causes built-up edge (BUE) on cutting inserts, and how can it be prevented?

Built-up edge occurs when material from the workpiece adheres to the cutting edge, disrupting surface finish. It is advised to select inserts with specific grades and geometries that minimize adhesion, alongside adjusting cutting parameters to reduce BUE occurrence.

Why does notch wear occur, and what can be done to prevent it?

Notch wear is localized at the depth-of-cut line and often results from work-hardened layers or abrasive inclusions. It is recommended to use ISCAR's advanced chipbreaker geometries and choosing the right insert grade to withstand abrasive conditions to prevent notch wear.

What strategies can prevent chipping or fracture of cutting inserts?

Chipping or fracture happens when cutting forces exceed the insert's mechanical strength, often due to improper feed rates or interrupted cuts. It is recommended to choose cutting parameters, selecting the appropriate insert grade, and ensuring regular inspection and maintenance to prevent such issues.
