The following specifications are given for a "HORIZONYTAL MILLING MACHINE Power and speed of the driving motor for speed gear box are 10 Kw., 1460 r.p.m. Power and speed of the driving motor for feed gear box are 3 Kw., 1450 r.p.m. Maximum and minimum cutting velocities= 200 & 15 mt./min. Maximum and minimum diameters of the milling cutters Number of speeds for the speed gear box Number of feeds Longitudinal feed Cross feed Vertical feed 150 & 45 mm. 18 speed 12 feed. 10: 635 mm/min. = 10: 635 mm/min. 3:195 mm/min. You are required to: (1) Draw the optimum structural diagram for the speed and feed gear boxes. (2) Draw the speed flow charts for the speed & feed gear boxes. (3) Calculate the number of teeth and diameter for each gear in the speed & feed gear boxes (Min. No. of teeth =18, Module = 4 mm ). (4) Draw the layouts of the speed and feed gear boxes showing how to obtain the min cutting and feed motions.
