Thus, the force equals pressure times the cross-sectional area of the cup wall. 2. Cutting force Cutting force is the force which has to act on the stock material in order to cut out the blank or slug.This determines the capacity of the press to be used for the particular tool. comparison table
The cutting speed (v) of a tool is the speed at which the metal is removed by the tool from the workpiece. Formula to calculate cutting processï½A.L.M.T. stainless Steel, Inch

10. Corp. has been meeting needs of society over half a century with tungsten and molybdenum that are materials having a ultra-high melting point, and heatspreader materials using these materials, electronic parts and functional parts, and with precision tools made of diamond and CBN. When this limitation is passed, the cutting speed (v c) will decrease until it reaches 0 m/min at the component centre. Taking the example of Fig. using formula: CF =L x S x Î¶max. Steel equivalent, Wrought
It can be divided into primary and secondary cutting forces. should a lathe be run to give a cutting speed of 25 metres / minute, when turning a rod of diameter 32 mm diameter. Draw clearance

#124 Press Forming Force (1) Blanking Force. 14. In general, cutting force (CF) can be calculated using the formula: CF =L x S x Î¶max Cutting force will be in Newton(N) Where, L = Cut length in mm,(perimeter of profile to be cut) Ex: 40 mm square to be cut will have cut length of 160 mm S = Sheet metal thickness in mm, Ready-to-Press Carbide Grade Powders; Thermal Spray Powders; Wear Components. The shearing angle is provided in the die in the case of blanking operations and in the punch in the case of hole punching operations. Cutting force in press tool. Carbide Wrought
This determines the capacity of the press to be used for particular tool. Conductivity
