MACHINING METALS Machining PRO’s and CON’s ADVANTAGES : 1. ONE OF OLDEST/ MOST IMPORTANT MANUFACTURING PROC’ 2. TO OBTAIN REQ’RD DIMENSIONAL ACCURACY (TOLERANCES) 3. TO OBTAIN SURFACE FLATNESS & FINISH 4. TO CREATE EXTERNAL & INTERNAL FEATURES (EASILY) 5. ECONOMICAL TO PRODUCE A SMALL NUMBER OF PARTS DIS-ADVANTAGES : 1. PROCESS WASTES MATERIAL 2. REQUIRE MORE ENERGY, LABOR, & CAPITAL THAN OTHERS 3. SHAPING BY REMOVING MATERIAL IS TIME CONSUMING, $ 4. MACHINING REQUIRES EXPERTISE OTHERWISE DAMAGE TO WORKPIECE IS LIKELY AND SURFACE QUALITY IS POOR

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
