Manufacturing Process for Making Steel

I need a very breif description (no more then 200) on how steel is made that address the following- - What process is used (i.e. product focus, process focus or group technology/cellular manufacturing - Anything surprising in the process - Is there anything that is particularly interesting or creative about the process - ...continues

Quantitative Master Production Scheduling

There are two steps in developing any MPS. Step 1: Calculate Projected On Hand Inventory (referred as “Available” in this problem table 1.) Available to Promise is the difference between the customer orders already booked and the quantity that operations is planning to produce. The procedure for calculation ATP is slightl ...continues

Magnetic Circuits

Given the relationship B/H=u H=IN/l and L=N*change in magnetic flux/change in coil current show that the inductance of a coil is: L=N^2/S where S=l/uA

Finding Metal Removal Rate

In an electrochemical machining operation, the frontal working area of the electrode is 2.5in squared. The applied current=1500amps, and the voltage=12volts. The material being cut is pure aluminum, whose specific removal rate is 1.26 x 10^-4 in^3/amp-min. If the electrochemical machining process is 90 percent efficent, det ...continues
