Cutting Tools used in Computer Numeric Control Machining - All details
Cutting Tool Materials ;
1. High Carbon Steel
2. High Speed Steel (HSS)
3. Cast Alloy
4. Cemented Carbide
5. Ceramics
6. Sialon
7. Diamond
8. Carbon Boron Nitride (CBN)
High Carbon Steel ;
Hardness of tool is determined by the carbon content which ranges from 0.65 to 1.5 %
More carbon content = More wear resistance.

What is Work ?
In our daily language, we use the word work for some sort of exertion, physical or mental or at times for various activities e.g. while writing we say that we are doing work.
But in Physics, the term work is used in relation to the movement of the force applied on the body. The work is said...
What is a transformer ?
A transformer is a device by which the amplitude of an alternating e.m.f. can be increased or decreased.
It does not affect the frequency of the alternating voltage.
It works on the principle of electromagnetic induction and makes use of two coils coupled together with a soft iron core.
Working Principle ;
A transformer cannot be used with direct...
Heat Treatment – A combination of operation involving heating and cooling under controlled conditions for obtaining desired properties in a material.
Heat Treatment also infulences creep resistance of steel. At temperature of 500 degree Celcius or above the max cree resistance is usually produced by normalizing, provided drawing temp. is about 100 degree more than the test temperature
The lowest creep resistance...
Hooke's Law ;
Sir Robert Hooke's (1635 - 1703 ) Law states that the stress is directly proportional to strain upto elastic limit.
Heat Treatment - A combination of operation involving heating and cooling under controlled conditions for obtaining desired properties in a material.
Those properties of a material that define its behavior under applied force are called mechanical properties.
