Lecture 8. Metal Cutting

A diamond abrasive wheel is used to cut the rod into slices. 4. To remove unwanted materials of a cutting process Example (a) Drilling and milling often leave tiny, sharp chips along the outer edges of the surface created by the tool – these are called burrs. Tapered grinding wheels are used to remove the burr (the process is called deburring).
