Problem la: A volume of 10 in. long, 5 in. wide and 0.5 in. thick is to be removed by a face milling cutter. The cutter is 3 in diameter and has a six teeth. The maximum depth of cut is 0.3 in. Assume feed -0.1 ipr and cutting speed - 200 fpm. What are the feed speed, spindle rpm and cutting time? Problem 1b: 0.95 The cutting force for turning a stainless-steel shaft using HSS tool can be predicted...
For a turning of a hot rolled free machining steel with BHN=200, you have selected a high-speed steel (HSS) tool and a depth of cut of 0.150 in. The diameter of the workpiece is 2.00 in. (a) What speed and feed would you select for this job? (b) Using a speed of 115 sfpm and the feed of 0.015 ipr, calculate the spindle RPM for this operation. (c) Calculate the metal removal rate MMR. (d) Calculate the cutting time for...
in an accelerated tool life test an HSS cutting tool shows a Flank wear of 0.01 inch in 1 minute of cur while cylindrically turning on a lathe a copper cylinder of 2 inch diameter and sinch long with a workpiece rotational speed 200 rpm and a tool feed rate of 0.01 inch per each rotation of the workpiece and a depth of cut 0.1 inch per pass. When only the workpiece rotational speed is increased to 300 rpm (and...
