A cemented carbide tool is used to turn a part with length = 18.0 in and diameter = 3.0 in. The parameters in the Taylor equation are: n = 0.27 and C = 1200. The rate for the operator and machine tool = $33.00/hr, and the tooling cost per cutting edge = $2.00. It takes 3.0 min to load and unload the workpart and 1.50 min to change tools. The feed = 0.013 in/rev. Determine: Cutting speed for maximum production rate, Tool life in min of cutting, and Cycle time and cost per unit of product.
In a conventional production, operations of turning, splines cutting and grinding are followed in sequence to produce splined shaft for gear boxes and lathe, milling and grinding machines are used for the operations. The reliability of the lathe, milling machine and grinder are 0.89, 0.87 and 0.93 respectively. It has been suggested that to improve reliability two identical machines could be used at each stage. If one fails the other can be used while the first one is being repaired. Another suggestion has been put forward to buy a CNC machining center with a reliability of 0.90 which will do the functions of the lathe and the milling machine. Calculate the system reliability for each of the 3 layouts and decide which is the most reliable
1. Enumerate at least 3 items that we should check prior to machining. 2. Enumerate the 5 minimum personal protective equipment (PPE) required during machining. 3. In case of emergency, where can we locate the emergency stop of milling machine? 4. In milling machine, how many axis can we operate the worktable?
In a turning operation of stainless-steel work part having shear strength = 378 MPa and tensile strength = 420 MPa, a coated carbide tool with a rake angle of 5 degrees is used to reduce its diameter from 100 mm to 93.2 mm with a cutting ratio of 0.45. During this process, a cutting speed of 2.4 m/s and feed of 0.24 mm/rev is used. Using the orthogonal model to approximate the turning process, how much power (W) will the lathe draw in performing this operation if its mechanical efficiency = 90%.
