What is the effect of increasing the rake angle of a cutting tool?
A slot of 25 mm \(\times\) 25 mm is to be milled in a workpiece of 300 mm length using a side and face milling cutter of diameter 100 mm, width 25 mm, and having 20 teeth. For a depth of cut of 5 mm, feed per tooth 0.1 mm, cutting speed 35 m/min, and approach distance and over-travel distance of 5 mm each, determine the time required for milling the slot.
In a DC arc welding operation, the voltage-arc length characteristic was obtained as \(V_{\text{arc}} = 20 + 5L\), where the arc length L was varied between 5 mm and 7mm. Here \(V_{\text{arc}}\) denotes the arc voltage in volts. The arc current was varied from 400 A to 500 A. Assuming linear power source characteristics, the open circuit voltage and short circuit current for the welding operation are:
In bulk metal forming, the load required for forging depends primarily on:
Which of the following is NOT a primary mechanism of material removal in Electrical Discharge Machining (EDM)
A 50 mm diameter disc is to be punched out from a carbon steel sheet 1.0 mm thick. The diameter of the punch should be
Match the processes with their characteristics:
A strip of 200 mm wide and 10 mm thick is reduced to 8 mm in one pass. Roll diameter = 100 mm, average flow stress = 200 MPa. Rolling load is:
In rolling of metals, when reduction per pass is increased while all other conditions are kept constant, the required rolling force
A solid cylinder of diameter 100 mm and height 50 mm is forged between two frictionless flat dies to a height of 25 mm. The percentage change in diameter is
