Answer 2

Properties of workpiece materials are:d ) all of the above

a)geometric features of the par

b. production rate and quantity

C. process selection consideration

• Understanding the workpiece material is most important as it gives the idea of opting the slice tools and machining parameters.
• But before knowing about the accoutrements is is important to understand the parcels of raw accoutrements . Some of the important parcels are as below

Rigidity – It's the measure of the distortion of a material plastically without fracture. Accoutrements with high rigidity produces nonstop chips whereas the low ductile accoutrements produce segmented chips. .

Durability – It's the capability of a material to repel impact or absorb the energy of an impact. A advanced durability will lessen the threat of cracking.

Machinability – It's defined as the ease at which the material can be machined.

Thermal conductivity – It's the rate at which the heat transferred through a material in steady state. If a material is having low thermal conductivity that simply means that the machinability of the material is low.

The heat dispersion in this will be less and tools will wear at veritably faster rate and erected up edges are formed.
