HW3: A block of steel has a length I. = 600 mm and a width W = 450 mm. The thickness is Machined 10 mm, once by Peripheral Milling and once by Planing Machine. Calculate Machining time for each operation if you know the following: 1. For peripheral milling: cutting speed V = 80 m/min, Feed f = 0.15 mm/rev, the cutter diameter D- 50 mm with five teeth and depth of cut d-3 mm. 2. For Planing: clearance on both sides e - 25 mm, cutting speed V = 36.56 m'min, return to cutting ratio m - 0.25, feed f-5 mm'stroke and depth of cut d- 5 mm. 3. Calculate Material removal rate in both Processes.

Forming and Shaping

Metal forming is a category of metalworking process through which the material can be given the desired shape and size by subjecting it to plastic deformation, where the component undergoes bulk deformation process upon application of loads. Unlike the shearing and machining process, the material does not undergo up to a failure point as indicated in the stress-strain curve. Hence, the stresses induced during the forming process are greater than yield strength but less than the failure strength of the material. The process does not lead to the loss of material, so it can be said to be an economical process. During forming, the material is subjected to tensile forces, compressive forces, bending, and shearing loading conditions. The material should possess the property of ductility to undergo the forming process.
