For turning operation, using the table below, find an approximate value for the required speed of rotation of the chuck, in rpm, if the cutting speed for the material 5417 mm/s and the radius of the wp is 0.01 m. Show details of your answer. n | we| o
2 1.54 Explain how you would go about estimating the C and n values for the four tool materials shown in Fig. 21.17.
In a turning operation, cutting speed =200 m/min; feed = 0.25mm mm/rev, and depth of cut = 4.00mm Thermal diffusivity of the work material = 20m mm^2/s and volumetric specific heat =3.5(10^ -3 )J/mm^ 3 -C If the temperature increase above ambient temperature (20degreesC) is the angle measured by a tool-chip thermocouple to be 700degreesC, determine the specific energy for the work material in this operation.

1. Peripheral milling is performed on the top surface of a rectangular work part that is 350 mm long by 60 mm wide. The milling cutter is 75 mm in diameter and has five teeth. It overhangs the width of the part on both sides. Cutting speed 55 m/min, chip load 0.25 mm/tooth, and depth of cut 5 mm. Maximum material removal rate during the cut will be mm/s.

A part surface is machined using single point cutting tool with feed rate of 0.3 mm/ rev. Given that, surface roughness is measured using centre line average method and details were given below, Sampling length = 0.8 mm Vertical Magnification = 10000 Horizontal Magnification = 100 Sum of areas above & below = 960 mm? What will be the Nose radius of cutting tool?
In a turning operation of stainless-steel work part having shear strength = 378 MPa and tensile strength = 420 MPa, a coated carbide tool with a rake angle of 5 degrees is used to reduce its diameter from 100 mm to 93.2 mm with a cutting ratio of 0.45. During this process, a cutting speed of 2.4 m/s and feed of 0.24 mm/rev is used. Using the orthogonal model to approximate the turning process, how much power (W) will the lathe draw in performing this operation if its mechanical efficiency = 90%.
