Machinability
Gives the idea of ease with which it can be machined.
The parameters influencing the machinability of a material are:
1. Physical Properties of material.
2. Mechanical Properties of material.
3. Chemical composition of material.
4. Micro-Structure of material
5. Cutting conditions.
Machinability of the material depends on various variable factors such as
1. Tool Life:
Longer tool life, it enables at a given cutting speed on the speed the better is the machinability.
2. Surface finish:
It indirectly proportional, i.e. better surface finish the higher in machinability.
3. Power Consumption:
Lower power consumption per unit of metal removal-better machinability.
4. Cutting Forces:
Lesser amount of cutting force required for removal of higher volume of metal under standard conditions, the higher will be the machinability.
5. Shear angle:
Larger shear angle denotes better machinability.
6. MRR:
Rate of metal removal under standard cutting conditions.
