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. |
