- Help!arrow_forwardWhat is dielectric? Discuss the impact of dielectric properties on machining characteristics in EDM in detailarrow_forwardA 600mm*30mm flat surface of a plate is to be finish machined on a shaper .The plate has been fixed with 600 mm side along the tool travel direction. If the tool over-travel at each end of the plate is 20 mm, average cutting speed is 8 m/min, feed rate is 0.3 mm/stroke and the ratio of return time to cutting time of the tool is 1:2 Determine time required for machining?arrow_forward
- 2. In EDM, please explain why the complimentary tool surface will be reproduced in the workpiece.arrow_forward(e) Briefly describe types of chips that occur in metal cutting. (f) For orthogonal cutting, the tool rake angle =15°. The chip thickness before the cut is 0.30mm and the cut yields a deformed chip thickness = 0.65mm. Calculate the shear plane angle and shear strain.arrow_forwardIn a turning operation, the workpiece diameter is Dm=44.00 mm and the diameter after the operation should be 22.00 mm. The cutting speed is set to 105.00 m/min and the federate is 0.03 mm/rev. Calculate the material 3 removal rate (Cm²Imin) for this operation (Do not input units). Your Answer: Answerarrow_forward
- In machining a mild steel work piece with carbide tool, the life of the tool was found to be 1 hour and 40 minutes, at a spindle speed of 30 m/min. Calculate the tool life if it has to be operated at a speed of 40% higher than the initial cutting speed. Also calculate the cutting speed if the tool is required to have a life of 2 hours and 45 minutes. Assume Taylor's exponent valuen is 0.28.arrow_forwardExplain the distinct features of non-conventional machining which gave it superiority over the conventional machining?arrow_forwardDraw the forces and angles involved in the cutting process and calculate shear angle (0), friction coefficient and tangential force if ,cutting force = 80 kN, resultant of forces =100kN, friction force=75kN, rake angle =20° undeformed chip thickness = 0.65mm and deformed chip thickness = 0.72mmarrow_forward
