Orthogonal & oblique cutting

Differences between orthogonal and oblique cutting

1. Orthogonal & Oblique Cutting Shivam Kumar 40925511116

2. What is Metal Cutting? Metal cutting is the process of producing a job by removing a layer of unwanted material from a given workpiece . 

3. Orthogonal Cutting The cutting edge of wedge shaped cutting tool is perpendicular to the direction of tool motion.

4. Oblique Cutting The cutting edge of wedge shaped cutting tool m akes an angle except right angle to the direction of tool motion . This will affect the cutting conditions .

5. Differences Orthogonal Cutting Oblique Cutting Chip flow is in the direction perpendicular to cutting edge. Chip flow is in sideways direction.

6. Differences Contd. This cutting is also known as 2D cutting because the force develop during cutting can be plot on a plane or can be represent by 2D coordinate.  It is also known as 3D cutting because the cutting force develop during cutting cannot be represent by 2D coordinate or used 3D coordinate to represent .

7. Differences Contd. High heat concentration at cutting region. Tool life is shorter as compared to Oblique cutting. Poor surface finish. Used in parting, grooving, slotting, pipe cutting Less concentration of heat at cutting region compared to orthogonal cutting. Tool life is more. Better surface finish Used in almost all industrial cutting drilling, milling, grinding
