Design 2D part and generate G code for the part. Assume a material for the work part. Select the proper cutting tool type and machining parameters (Feed, speed and depth of cut) in order to machine the part. Based on your assumptions: a. Calculate the material removal rate b. Calculate the machining time c. Use the Taylor Tool Life equation to estimate the tool life for this operation (search for representative values of n and C in the Taylor tool life equation for your selected tool materials). How many such parts would you be able to machine before the tool needs to be replaced? d. Estimate the rise in temperature at the tool-chip interface during the operation (in F or °C). How close is the adiabatic temperature rise to the melting point? T= 0.4U vt ск 0.333 where T = temperature rise at tool-chip interface; U = specific energy; v = cutting speed; to = chip thickness before cut; pc = volumetric specific heat of work material; K = thermal diffusivity of work material. e. Estimate the power (in hp or W) required for this operation. f. How much power will the macine draw in performing this operation if its mechanical efficiency = 90%. The specific energy requirements in cutting operations are listed in table below: Approximate specific-energy requirements MATERIAL SPECIFIC ENERGY J/mm³ hp-min/in³ Al alloys 0.4-1.1 0.15-0.4 Cast irons 1.6-5.5 0.6-2.0 Copper alloys 1.4-3.3 0.5-1.2 High-Temp alloys 3.3-8.5 1.2-3.1 Mg alloys 0.4-0.6 0.15-0.2 Ni alloys 4.9-6.8 1.8-2.5 Refractory alloys 3.8-9.6 1.1-3.5 Stainless steels 3.0-5.2 1.1-1.9 Steels 2.7-9.3 1.0-3.4 Titanium alloys 3.0-4.1 1.1-1.5
