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.

Consider a milling process, where a pocket with width (X) of 400mm, Length (Y) 300mm, and depth (z) of 15 mm. The cutting tool is a 12 mm diameter flat end mill with 4 cutting edges. For some reason, the tool can be radially immersed in the material at most 50% of the tool diameter. The spindle speed is selected as 2000 rpm, where the max allowable axial cutting depth is 2.5 mm. a) Calculate the number of total cutting steps, indicating which feed direction would you prefer x or y. It may be preferred to have feed rate can be along X direction Total # of cutting steps: If feed direction is along X, the total number of cutting steps is 294 b) Calculate the minimum achievable cycle time if the feed rate is 0.15 mm/rev/tooth. Approx cycle time: 98 minutes
Find the machining time to complete the job as shown below from the basic raw material of 50 mm diameter and 100 mm length.
