Study and Analysis of Material Removal Rate on Lathe Operation with Varing Parameters from CNC Lathe Machine Gaurav Pant 1, Shivasheesh Kaushik 2, In order to improve the quality and to reduce the cost material removal rate should be optimum. In machining accurate dimensions is desired but with good product quality.
The grinding process has the least material removal rate among other machining processes because of the following reasons Size effect: As above discussed the machining is done by the abrasive action of grinding wheel thats why a large portion of the abrasive will be embedded inside the wheel and a small portion of abrasive will be allowed to interact with them, therefore, less material is
the practical material removal rate in machining internal cylindrical Several methods exist for the calculation of operation time of machining. be compared because in grinding the material.
Metal removal rate, Q (cm 3 /min) The volume of metal removed in cubic mm per minute (inch 3 /minute). It is established using the values for cutting depth, width and feed. Specific cutting force, k ct. A material constant which is a factor used for power calculations, expressed in N/mm2. Machining time, T c

Material removal rate, MRR AbrasiveFlow Machining Schematic illustration of abrasive flow machining to deburr a turbine impeller. The arrows indicate A deburring operation on a robotheld diecast part for an outboard motor housing, using a grinding wheel.
Metal removal rate (MRR) and spindle speed (n) were calculated for each of selected workpiece diameters. The results of calculation are shown in Table 1. Calculated volume of chips removed reports that provide the machining details an operator needs to correctly set up a machine and perform the required machining operations.

Metal removal rate, Q (cm 3 /min) The volume of metal removed in cubic mm per minute (inch 3 /minute). It is established using the values for cutting depth, width and feed. Specific cutting force, k ct. A material constant which is a factor used for power calculations, expressed in N/mm2. Machining time, T c (min)
Material Removal Rate: Roughing removes large amounts of material, at high feeds and depths, low speeds Finishing Achieves final dimensions, tolerances, and finish, Low feeds and depths, high cutting speeds = MRR v f d

A moderate removal rate of Q = 50 mm 3 /s over a 25mm wide cut is quoted as Q = 2 mm 3 /s per mm width or 2 mm 2 /s equivalent to in. 2 /min in British units. In HEDG, a possible removal rate as high as Q = 1200 mm 3 /s over a grinding width of 2 mm translates to Q = 600 mm 2 /s (or in. 2 /min).
Material removal rate, MRR v = workpiece velocity, d = depth of cut, b = width of cut 23 l D d MRR v d b

#0183;#32;Diamond grinding, as a major process for machining ceramics, suffers from low material removal rates and high tool wear . Therefore, some new machining processes such ultrasonic grinding [ 5 ] and laserassisted grinding (LAG) [ 6 ] have been developed in order to increase material removal rates, prolong the tool service life and enhance the surface integrity of the workpiece.
