- Machine setup steps should be stated in bullet points for ease.arrow_forwardA NC lathe cuts two passes across a cylindrical workpiece under automatic cycle. The operator loads and unloads the machine. The starting diameter of the work is 3.00 in and its length = 10 in. The work cycle consists of the following steps (with element times given in parentheses where applicable): 1 - Operator loads part into machine, starts cycle (1.00 min); 2 - NC lathe positions tool for first pass (0.10 min); 3 - NC lathe turns first pass (time depends on cutting speed); 4 - NC lathe repositions tool for second pass (0.4 min); 5 - NC lathe turns second pass (time depends on cutting speed); and 6 - Operator unloads part and places in tote pan (1.00 min). In addition, the cutting tool must be periodically changed. This tool change time takes 1.00 min. The feed rate = 0.007 in/rev and the depth of cut for each pass = 0.100 in. The cost of the operator and machine = $39/hr and the tool cost = $2.00/cutting edge.

For safety reasons, these threesetup activities must be done sequentially. The programmed machining cycle takes 3.75 min.Cutting tools wear out and must be periodically changed, which takes 6.0 min every 20 cycles andis performed by a human worker. At the end of each machining cycle, the robot reaches into themachine and removes the just-completed part, places it in a parts storage carousel, then reachesfor a starting work part from the same carousel and places it in the machine tool fixture. Thissequence of handling activities takes 45 sec. The storage carousel holds 25 parts. At the beginningof the production run, it is full of raw work parts. As each part is retrieved by the robot, the carouselindexes one position to present a new raw…arrow_forward
