A flat milling operation will be carried out with a horizontal milling machine, in a piece of 250 mm in length and 50 mm in width, using a felicoidal bur with a diameter of 75 mm, with 10 teeth. If the feed per tooth is 0.2mm, and the cutting speed is 0.75 m / s, how would you determine the speed of metal removal to remove 6 mm from the surface of this piece?
A 78 mm thick plate is to be milled down to a thickness of 60 mm using an 80 mm face milling cutter. Calculate the processing time if the cutting depth is 6 mm, the feed/rev is 1.1 mm and the cutting speed is 15 m/min, and if the over run for a 620 mm long plate is 10 mm.
In face milling, assume that the Diameter of the cutter is 200 mm, the width of the block is 60 mm, and the length of the block is 344 mm, if the depth of cut is 3 mm, = 0.6 mm/min, and N = 100 rpm. The cutter has 12 inserts, and the workpiece material is bronze. Calculate the estimated power required, the cutting force, and the torque.
