Abrasive processes (examples)

finishing operations

material removal process generally used as

a material removal process in which abrasive particles are contained in a bonded grinding wheel that operates at very high surface speeds

Grinding is a ____

consists of abrasive particles

grinding wheel consists

four

how many types of surface grinding

horizontal spindle with reciprocating table

horizontal spindle with rotating worktable

vertical spindle with reciprocating table

vertical spindle with rotating table

wear resistance, wheel grade, wheel structure, bonding material, high hardness

Grinding wheel parameters

high temperature and high friction

Grinding is characterized by

decrease infeed, use grinding fluid, reduce wheel speed,

reduce Temperature when grinding

expose new sharp gains, remove chips clogged in wheel

resharpening the wheel

A process in which a **sharp cutting tool** is used to mechanically **cut the materials** to achieve the geometery

Machining

**shear deformation** of work material to form a **chip**

cutting action involves
