Chapter 24, Problem 9P

Suppose you want to do the job described in Problems 6 by slab milling. You have selected a 6-in.-diameter cutter with eight TiN-coated carbide teeth. The cutting speed will be 500 sfpm and the feed per tooth will be 0.010 in. per tooth. Determine the input parameters for the machine (rpm of arbor and table feed), then calculate the Tm and MRR. Compare these answers with what you got for slab milling the block with HSS teeth.

Two identical cylindrical jobs are turned using (a) a round nosed tool of nose radius 2 mm and (b) a sharp corner tool having principal cutting edge angle = 45° and auxiliary cutting edge angle = 10° If the operation is carried out of the teed of 0.08 mm/rev will Find the height at micro irregularities on the machined surfaces (in mm) in the two cases.
thickness is HW3.A block of steel has a length L-600mm and a width W-450mm. The Machined 10mm, once by Peripheral Milling and once by planing Machine.Calculate :Machining time for each operation if you know the following For peripheral milling: cutting speed V =80 m/min, Feed f-0.15mm/rev, the cutter .1 diameter D =50 mm with five teeth and depth of cut d =3mm For planing: clearance on both sides c =25mm, cutting speed V =36.56 m/min, retum to .2 cutting ratio m =0.25, feed f=5 mm/stroke and depth of cut d =5 mm .Calculate Material removal rate in both processes .3 Solution
It takes only 12 seconds to mill 0.5" x 5.5" keyway by means of a 40-tooth cutter at a feed rate of 0.249 mm/tooth. Compute the required speed of the cutter in rpm. 70 O65 O 60 75 A
