Analysis of Orthogona – Machining – Manufacturing Technology ME
Real life Application-
The analysis in orthogonal machining helps in determining the power required for machining, the rigidity of machine tool, the temperature induced and hence the hot hardness temperature, and eventually the quality of production.
The orthogonal cutting operation is the one where in the cutting edge is perpendicular to the cutting velocity
1. The tool is perfectly sharp
2. The surface where shear occur in a plane
3. The cutting edge is a straight line perpendicular to the motion.
4. The chip does not an either sides.
5. Uncut chip thickness is constant.
6. Width of the tool is greater than that of work piece.
7. A continuous chip is produced without BUE.
8. Work moves with uniform velocity
9. The stresses on the shear plane are uniformly distributed.
Whereas rest are unmeasurable and they occur in a dynamic environment. Thus, there is a need of establishing a relationship between them.
This can be done using a graphical approach called Merchant’s Circle, by representing the forces with lines indicating their magnitude through the length and direction.
I am Praveen. I got AIR 1 in Instrumentation stream. I want to dedicate this to my parents and to the Gate Academy faculty. Gate Academy coaching helped me tremendously to update myself continuously.I was very impressed with the way they taught each topic in different sessions with separate material for each session.
E Lectures helped me a lot in making a head start in the right direction. It helped whenever I got stuck in any topic. Mock Tests across 50 centers helped me judge my progress both on individual and comparative basis.
To begin with, it gives me immense pleasure to Thank,Thank the institute THE GATE ACADEMY for all their help and support.Its a place to learn, explore, grow and succeed.Well it helps you brush-up your engineering knowledge and learn new things and clears your concept in such great details
THE GATE Academy questions covered a wide variety of topics and were similar to GATE paper standard. The online platform replicated the actual GATE test environment and the detailed and video solutions were sufficient to clear all doubts regarding the question. Thanks to THE GATE Academy team to provide such wonderful tests & platform.
In one year’s time, I was able to prepare for GATE exam with the help of THE GATE ACADEMY and faculties. GATE Focused study materials and online mock tests helped me know my strengthen & weakness to prepare accordingly. I wish all the best to all GATE aspirants and suggest them to go through GATE coaching in case the basics are not clear.
I took up mechanical coaching at THE GATE ACADEMY as there is no separate coaching for Engineering Sciences in India and Mechanical and Engineering sciences have more or less common topics.I feared that cracking GATE would be very difficult because I started my preparations very late but the counsellors and teachers guided me
GATE Success Story
- Our students get all India rank 1, 1, 1, 1, 4 and 4
- More than 142 students in top 100.
