Difference between Machining and Grinding

Distinguish, differentiate, compare and explain what is the difference between Machining and Grinding. Comparison and Differences.

Differences between Machining and Grinding

S.No. Machining Grinding
1 Bulk material removal process (high MRR). Surface finishing process (low MRR).
2 Achievable surface finish is below 10 micrometer. Improved finish can be obtained between 0.5 to 2 micrometer
3 Poor accuracy and tolerance is offered. High accuracy and tolerance is achievable.
4 Cutting tool is made of metallic (carbon steel, HSS, etc.) as well as non-metallic materials (cBN, diamond, ceramics, etc.). Grinding wheel is made of abrasives like alumina, silica, diamond, cBN, etc., which are bonded in a suitable medium (like resin).
5 Cutting tool has pre-defined geometry. Abrasives has random geometry.
6 Rake angle usually varies from -15o to +15o. Rake angle may vary from -75o to +75o.
7 Usually each main cutting edge of the tool actively and equally participates in material removal action. Only few (about 1%) abrasive grits actually engage in material removal action (shearing). Many dont even tough the workpiece.
8 Specific energy consumption is lower. Specific energy consumption is high.
