tool point of the cutter moves with respect to the work measured in feet per minute. Feed is the rate at which the work moves into the cutter measured in feed per tooth revolution. Feeds and speeds affect the time to finish a cut, tool life, finish of the machined surface and power required of the machine.
CNC Tool and Cutter Grinder Idea Notebook. Imagine a Tool and Cutter Grinder capable of sharpening any tool under full CNC control. At this scale, cutter grinding involves relatively small workpieces, so a giant machine is not called for. Perhaps even a small hobby CNC machine would be able to do this kind of work with a high degree of success.

Grinding machine is a type of machine tool and it is similar to other machine tools such as milling machine, turning machine, Lathe Machine and many more. The major difference between Grinding machine and other conventional machine tools is the type of operation and method of machining. Generally, all the machining process removes material from ...
Further grinding and polishing is then needed to smooth the surface to its final form. Blocking and Grinding Before the lens undergoes further grinding, the lens must be blocked, or mounted, to begin the process. Blocking involves mounting lenses onto a convex or concave surface (inverse of the tool being used) with pitch or wax.
Grinding is a surface finishing operation where very thin layer of material is removed in the form of dust particles. Thickness of material removed is in range of 0.25 to 0.50 mm. Tool used is a abrasive wheel
