Shaping Planning Machines •Shaping and planning are similar operations. •Cutting tools used in both operations are singleedge cutting tools to create a straight and flat surface. •Interrupted cutting occurs in them, subjecting the tool to an impact loading upon entry into the work. •These machines are limited to low speeds due to their start
Grinding. Grinding Grinding is a material removal process accomplished by abrasive particles that are contained in a bonded grinding wheel rotating at very high surface speeds. The rotating grinding wheel consists of many cutting teeth ( abrasive particles ) and the work is fed relative to the rotating grinding wheel to accomplish material removal.
In a grinding machine, there is an electric motor which supplies the motion power to the grinding wheel with the help of a belt and pulley.. So when we start the electric motor the motor rotates at a certain rpm ( RPM, it may change according to the types of grinding machine) with the help of vbelt and cone pulley the grinding wheel also starts rotating and we perform the operation.
Mar 02, 2017· Machining Operations and PartMachining Operations and Part GeometryGeometry Each machining operation produces a characteristic part geometry due to two factors: 1. Relative motions between the tool and the workpart • Generating – part geometry is determined by the feed trajectory of the cutting tool 1.
