hard-tomachine materials. Drilling is one of the important machining processes for these materials. Industries are always under tremendous pressure to meet the ever-increasing demand for lower cost and better quality of the products made from these high-performance materials. Rotary ultrasonic machining (RUM) is a non-traditional machining process that combines the material removal mechanisms of diamond grinding and ultrasonic machining. It is a relatively low-cost‚ environment-benign process that

are relatively inexpensive. On the other hand‚ defects can arise if the metal solidifies too soon and prevents the mold from filling completely. The surface finish of cast components generally has a rough texture‚ and they might require additional machining operations to produce smooth and flat surfaces. Some examples of cast components include automotive engine blocks‚ cylinder heads‚ and brake rotors and drums. One kind of a forming operation is called rolling‚ which is the process of reducing

Interchangeability parts were invented to repair broken things. For example‚ if something broke‚ you can buy interchangeable parts and replace the broken piece. Interchangeable parts were achieved by combining a number of innovations and improvements in a machining operation. Such as‚ slide rest lathe‚ screw-cutting lathe‚ milling machine and metal planer. After this was invented‚ everything for those who need something became easier. Things became easier for everyone and engineers‚ the most because they use

has been successfully done and tested using an upright drilling machine. For different sizes of holes less than 20mm the tool can be changed. Similar designs can be made for any size and any number of sides to avoid lot of setting time and pre-machining procedures involved in current methods and very useful in case of mass production. INTRODUCTION Coimbatore is a highly industrial city. This is mainly due to entrepreneurship of local peoples. As there is no public sector undertaking. The

Abstract This paper proposes a design of jigs and fixtures for the mass production manufacturing of Sportsman Race Series aluminum slipper pistons (Probe Industries) that are used in the Chevrolet LS Series V8 engines. The designs of two sets of jig and fixture designs are proposed. The first set (two vee-blocks and a drill bushing) is designed for the process of drilling the wrist pin holes in the piston. The second design (two vee-blocks and a pin locator) is used in the milling of the skirts

2k factorial trial was utilized to describe the impacts of machining components‚ cutting depth‚ shaft speed and feed rate at first glance roughness of the sleeve. The outcomes demonstrate that the surface roughness was minimized when the shaft speed and feed rate were situated to the most abnormal amounts while the depth of slice was situated to the least level. Despite the fact that the outcomes from this exploration were procedure particular‚ the system sent can be promptly connected to distinctive
