The workpiece of size 50 mm x 90 mm length is to be reduced to 0 42 mm x 85 mm. If the depth of cut is 0.5 mm, feed is 0.25 mm/rev and cutting speed is 45 m/min find the time taken to complete one job and production rate at the end of 8 hr shift.
An aluminum hollow shaft 200 mm outside diameter, 100 mm inside diameter and 500mm length from lathe chuck is to be face turned at the end. Its end face is finished at arotational speed of 400 rpm using a feed rate of 0.25 mm/rev. The side cutting edge angleor lead angle of the tool is 300. How much cutting time and maximum power is needed tofinish the facing operation with a 4 mm depth of cut. What is likely to be aperpendicularity error in this operation? Specific cutting energy = 0.025 W/ mm3/min andE = 50 kN/mm2.
Question 1. The shaping machine is used to machine flat metal surfaces especially where a large amount of metal has to be removed. The shaper machine is a reciprocating type of machine basically used for producing the horizontal, vertical or flat surfaces. The shaper holds the single point cutting tool in ram and workpiece is fixed in the table. A shaper mechanism is designed to give a slow cutting stroke and a quick return to a blade attached to the slider at C. Determine the velocity of the slider block C at the instant 0= 60°, if link AB is rotating at 4 rad/s. 125 mm C 45 B WAR =4 rad/s 300 mm
