Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. This may be done by varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations. It is one of the most commonly used processes for machining custom parts to precise tolerances. A torque of 500 N-m is developed in the cutter under steady-state cutting conditions. One of the 16 teeth on the cutter breaks during the cutting operation. Determine the cross-section of the arbor to limit the amplitude of angular displacement of the cutter to 1°. Assume that the arbor can be modeled as a hollow steel shaft fixed at both ends. Data: Length of arbor 0.5 m, mass moment of inertia of the cutter 0.1 N-m², speed of cutter = 1000 rpm.

Automated industrial system can increase the quality and flexibility of process.(i) Sketch an automated industrial system and briefly describe the elements of the automated industrial system.(ii) With the aids of the sketched automated industrial system in Q1(a)(i), illustrate and label the appropriate components for all the elements in an automated metal and plastic objects sorting process with conveyor system.
A company makes two kinds of door Knobs, standard and deluxe ,the making process cost the company 15$ for the standard and 20$ for the deluxe by making on a grinder and a smoother machines, which they can be run for at most 80 hours a week, each standard one needs 2 hours on the grinder, and 4 hours on the smoother, and each deluxe one needs 4 hours on the grinder and 3 hours on the smoother ,the company sales at 25$,35$ for the standard and the deluxe respectively. To have the profit it wants the company decide to make at least 15 knobs from them at a week, formulate the linear programming model?

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
The CNC grinding section has a large number of machines devoted to grinding shafts for the automotive industry. The grinding machine cycle takes 5.6 min. At the end of this cycle an operator must be present to unload and load parts, which takes 120 sec. a) Determine how many grinding machines the worker can service if it takes 45 sec to walk between the machines and no machine ideal time is allowed. b) How many seconds during the work cycle is the worker idle? c) What is the hourly production rate of this machine cluster?
A certain job shop specializes in one-of-a-kind orders dealing with parts of medium-to-high complexity. A typical part is processed sequentially through 10 machines in batch sizes of 1. The shop contains a total of eight conventional machine tools and operates 40 hr/wk of pro duction time. Average time values on each part per machine are: machining time = 0.5 hr, work handling time = 0.3 hr, tool change time = 0.2 hr, setup time = 3 hr, and non operation time = 12 hr. A new programmable machine is being considered that can per form all 10 operations in a single setup. The programming of the machine for this part will require 20 hr; however, the programming can be done off-line, without tying up the machine. Setup time will be just 2 hr because simpler fixtures will be used. Total machining time will be reduced to 80% of its previous value due to advanced tool control algorithms; work han dling time will be the same as for one machine; and total tool change time will be reduced by…

On Robotic Hand, search at least two of any related machine that applies the said technology and in five sentences discuss its features.
A batch of 35 parts is ordered by a customer about every six months. The parts are currently processed sequentially through five conventional machines, listed in the following table with setup times and work cycle times per piece. These machines all require an operator to be in attendance during the work cycle. There is a delay of 10 hr/machine dueto transport between machines and waiting in queues of other parts processed by thesemachines. A recommendation has been made to process the parts on a new multitaskingmachine that would complete the batch in one setup, which would involve a simple fixtureand a setup time of 2.0 hr. The work cycle on the multitasking machine consists of thesame operations that are accomplished by the five machines, but the cycle time would beless than the sum of the five cycle times by one-half because of tool path improvementsand reduced part handling. Determine the manufacturing lead time (how long it takes tocomplete the batch of 35 parts, including…
