- QUESTION 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_forward1. Why are nontraditional machining methods (NTM) required as compared to conventional machining methods? 2. What industries have benefitted from the development of NTM operations? 3. Select an industry and describe how the industry you have chosen uses nontraditional machining in its manufacturing.arrow_forwardBroadly define what machining processes are.arrow_forward
- For 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_forward5. What are the adverse effects of tool wear in cutting processes? 6.

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
- List four industries that depend on machining. How do you understand English and metric(SI) measurement systems and perform conversions between the two? List the two most common methods for measuring surface finish. what is the difference between ferrous and nonferrous metal. What is purpose of the layout? Briefly contrast the difference between drilling and reaming operations. How do you understand this class of Precision Machining Technology?arrow_forward(a) Modern Machining Processes (MMP) is an alternative machining process which traditional cutting tools are not used. Instead, energy at its direct form is utilized to machine work piece. Briefly describe the three (3) categories of modern machining and at least two (2) reasons when its needs to use EDM and USM in machining process.arrow_forwarda) 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_forward
