process started on September 24 by submitting layouts and engineering drawings of C-Clamp to our professor. We started machining process with bench work the week after. Drilling and trade calculations were done during the week of October 22. As drilling is very convenient and fast, we were one week ahead from our schedule. We started milling operation as it is a lengthy machining process and hard because we have to be very careful with our measurements, and it took two weeks to finish. We just finished

Reduction of Wrinkling Defect in Deep Drawing Process Abstract. The aim of this experiment is to obtain the best parameters for reducing wrinkle defect during deep drawing process. Deep drawing is a sheet metal forming process where a punch is utilized to force a flat sheet metal to flow into the gap between the punch and die surfaces. Due to that, the sheet metal will deformed into the desired shape. Some of the most common outcomes in deep drawing process are tearing and wrinkling or the formation

PROCESSES Metal cutting, commonly called machininh, is the removal of unwanted portions from a block,plate of material in the from o chips so as to obtain a finished product of desired dimensions, finish.Most of the manufactured products require machining at some stage of their production, ranging from rough work to high precision work.Hence metal cutting is the most important of the basic manufacturing processes. In all metal cutting operations an edged tool driven in to the material to remove chips

Matrix Composites (Al-MMC) are widely used in aeronautical and automobile industries due to their excellent mechanical and physical properties. However machining this composites find difficult because of the reinforcement particles. Tools wear more quickly and reduce the life of the tool. This paper presents the experimental investigation on machining two different A356 matrix metal reinforced with 10 % and 20 % by weight of Silicon carbide (SiCp) particles is fabricated in house by stir casting method
