Tool Failure | definition in addition to Types

Tool failure

Tool vesture is a gradual phenomenon of failure of the tool due to its operating conditions.There is an equation which provides the human relationship betwixt several aspects of the tool.

Moreover inward general

• If surface hardness tool > surface hardness of workpiece thus no substantial increment inward tool vesture amongst speed increase.
• If surface hardness tool < surface hardness of workpiece thus in that place is the substantial increment inward tool vesture amongst speed increase.

Tool failure is 2 types

1. Slow death: The gradual or progressive wearing away of rake human face upwards (crater wear) or flank (flank wear) of the cutting tool or both.

2. Sudden death: Failures leading to the premature destination of the tool predict. Tool failure mechanisms include plastic deformation, brittle fracture, fatigue fracture or border chipping. However, it is hard to predict which of these processes volition dominate as well as when tool failure volition occur.

Types of Tool Wear

(a) Flank Wear
(b) Crater Wear
(c) Chipping off of the cutting edge
