- List four industries that depend on machining.arrow_forwardInvestigate the non-traditional machining methods. Describe each in your own words and sketch out the process and appropriate scale (inches/microns etc). Then tabulate the material removal mechanism, workpiece materials, applications, costs/speed, advantages and limitations/disadvantages of each. The slides are for your starting point. List references, articles, videos, etc... Mechanical Methods 1. Water Jet Machining (WJM) 2. Abrasive Water Jet Machining (AWJM) 3. Ultrasonic Machining (USM) Non-Mechanical Methods 1. Electrochemical Machining (ECM) 2. Electro-Discharge Machining (EDM) 3. Wire EDM 4. Laser Drilling 5. Electron beam machining (EBM)arrow_forwardQUESTION 2 Tool life is the most important factor in the evaluation of machinability. Tool life can be defined as the period of time which the tool cuts effectively and efficiently. A cutting tool should have a long tool life. On the other hand, the cutting speed decreases the tool life due to the abrasive action that occurs between the cutting tool and materials. The increase in cutting speed will decrease the machining time, thus reduce the total machining cost. Justify what actions should be taken to increase the tool life and at the same time shorten the machining time.arrow_forward
- Broadly define what machining processes are.arrow_forwardFor the following application, identify one or more nontraditional machining processes that might be used, and present arguments to support your selection. Assume that either the part geometry or the work material (or both) preclude the use of conventional machining. The application is a through-hole in the shape of the letter L in a 12.5 mm (0.5 in) thick plate of glass. The size of the "L" is 25 by 15 mm (1.0 by 0.6 in) and the width of the hole is 3 mm (1/8 in).arrow_forwardFor the following application, identify one or more nontraditional machining processes that might be used, and present arguments to support your selection. Assume that either the part geometry or the work material (or both) preclude the use of conventional machining. The application is a blind-hole in the shape of the letter G in a 50 mm (2.0 in) cube of steel. The overall size of the "G" is 25 by 19 mm (1.0 by 0.75 in), the depth of the hole is 3.8 mm (0.15 in), and its width is 3 mm (1/8 in).arrow_forward

- a) A face milling operation is not yielding the required surface finish on the work. The cutter is a four-tooth insert type face milling cutter. The machine shop foreman thinks the problem is that the work material is too ductile for the job, but this property tests well within the ductility range for the material specified by the designer. Without knowing any more about the job, describe THREE (3) changes in i. cutting conditions ii. tooling would you suggest to improve the surface finish?arrow_forwarding the work part to be an anode. 14) In electrochemical machining, the electrode is fed into the work at a rate ---------- the rate of metal removal from F) making the work part to be the work.
