- For straight turn of a 6 x 1.1-inch dia. into 1in finished diameter material. What is the time required to finished a cut when the depth of cut is 0.02 inch and the feed rate 5 inch / sec, RPM is 60. The subject is Machine Shop TheoryE Expert Q&A 1. Shaper (#X) Machine function and design requirements: The main function of this machine is to make surface more smooth; The required movements are: Reciprocating movement of planer knife and feed movement of the bow. It is required that the cutting speed is uniform, while the quirkily return is included. The basic data is: principal axis rotation speed is 60 r/min, the max length is less than 450 mm, the distance between working surface and the floor is 800 mm. Travel speed ratio co-efficient is 1.5, allowable pressure angle 15°, cutting quantity is 0.1~0.5 mm. Requirements: 1. Freedom calculations; 2. Force analysis; 3. Make this machine, and display; please give a solution with given condition.A 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. The applicable Taylor tool life equation has parameters: n = 0.26 and…
