Using slot milling with a cutting tool surface width of 36mm was performed from the top surface to cut a workpiece of 85 x 42 x 8 cm into two equal parts. The milling cutter is 180 mm in diameter and has eight teeth. Cutting speed = 60 m/min, chip load = 0.35 mm/ tooth, and depth of cut = 2 mm, given that the setup and machine settings provide an approach distance of 7mm before actual cutting begins and an overtravel distance of 20 mm after actual cutting has finished, and the return time is a 4-second for idle pass stroke. Determine:- 1. What is the total machining time required for the entire workpiece? 2. The maximum metal removal rate during cutting.

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.

Question

Using slot milling with a cutting tool surface width of 36mm was
performed from the top surface to cut a workpiece of 85 x 42 x 8 cm into
two equal parts. The milling cutter is 180 mm in diameter and has eight
teeth. Cutting speed = 60 m/min, chip load = 0.35 mm/ tooth, and depth of
cut = 2 mm, given that the setup and machine settings provide an approach
distance of 7mm before actual cutting begins and an overtravel distance of
20 mm after actual cutting has finished, and the return time is a 4-second
for idle pass stroke.
Determine:-
1. What is the total machining time required for the entire workpiece?
2. The maximum metal removal rate during cutting.

In turning of stales steel alloy, 1100 mm length and 400 mm diameter, the Feed was 0.35 mm/rev, and depth of cut = 2.5 mm. The tool used in this cutting is cemented carbide tool where Taylor tool life parameters are n = 0.24 and C = 450 (tool life (min) and cutting speed (m/min). Compute the cutting speed that will allow the tool life to be 10% longer than the machining time for this part.
