A pre-drilled hole of $10 mm in a block of 40 mm thick is required to be enlarged to 0 16mm by core drilling process as shown in the figure below. The recommended cutting speed and the feed rate are 25 m/min. and 0.2 mm/rev respectively. The specific energy of block material is 4.0 W-s/mm³.Calculate the following a) Material removal rate (mm³/s) b) Power required for machining (W). c) Time required for machining. (Sec.) d) Total material removed (mm³) e) If the HSS core drill bit used obey the Taylor's tool life equation VT0.14 the bit can enlarge before it is replaced? f) Is the above drilling operation can be done on an available drill press of 500 watts power with 80% efficiency? Check and show with calculation. = 35 (m/min), how many holes

Machining Processes and Machine Tools

Machining is represented as the process in which an excessive amount of substance is eliminated from the particular element in the form of pieces. In machining, cutting tools such as rotary tools, lathe, drill press, grinder, chop saw, welders, and many more are applied to get the desired shape. As compared to other manufacturing processes, machining is precise and versatile.
