EFFECT OF PVD COATED TOOLS ON EUTECTIC ALUMINIUM ALLOY DURING DRY MACHINING PROCESS
No full textAluminium Alloy is widely used in various Industries like Aerospace, Automobile etc. due to their peculiar character weight by volume ratio. Addition Silicon not only increases the strength of the alloy but also helps to perform smooth machining. Silicon in the Al alloy is about 12% is commonly known as Eutectic Al Alloy. Machining is a further challenge for this Eutectic alloy. Dry machining process is an economic and environmental healthy process. In the present study Eutectic Aluminium alloy is machined using PVD coated HC,AlTiN and Uncoated Carbide cutting tool. Minitab statistical software is used to produce L27 Array for 3 factor and 3 levels of variables to conduct turning experiment. Average Surface roughnesses are recorded to optimize the cutting parameters for each tool using Taguchi analysis for the dry machining process. Hard Carbon coated tool machining gives minimum Ra= 0.615 µm at 2000 rpm Speed, 0.02 mm/rev feed rate and 0.25mm depth of cut.

EXPERIMENTAL STUDY ON STRENGTH OFCONCRETEBYPARTIALREPLACEMENTOFCOARSEAGGREGATEBYLATERITESTONE
No full textConcrete is one of the most extensively used building material. Scarcity and non-available of coarseaggregate at affordable cost affected adversely on the construction industry.So using alternative material(lateritestone)forcoarse. The experiment is mainly aimed to study the structural properties of concrete mix in which coarse aggregate is partially replaced by lateritre stone. Concrete mix contains 0%, 20%,25%,30%,35%,40%, 45% and 50% of coarse aggregate replaced by laterite stone. Here it is observed that whenupto25% of coarse aggregate is substituted by laterite stone aggregate the concrete strength like compressive andsplit tensile has been boosted. Whereas the workability of concrete decreases with increase of percentage oflaterite stone as coarse aggregate. We got maximum compressive strength 42.63 N/mm2 and split tensilestrength of 11.55 N/mm2 of 25% replacement of laterite stone for M30 grade. Hence from above results we conclude that compare to conventional concrete 25% of coarse aggregate can be replaced by later it estone

MANUFACTURING OF LEAF TYPE DRILL JIG
No full textDrill is device used to locate and clamp the work piece as well as it guides the tool. Jig is mainly used for mass production. For large scale production of different material, a lot of time is wasted in setup of device and clamping the device. Trial and error method is usually practiced until the axis of work is properly aligned with axis of drill. In such a situation a lot of time is being wasted to maintain the accuracy. Eventually it increases the operator’s fatigue. Thus, drill jig can increase productivity by increasing individual positioning, marking and frequent changing. The main advantage of the jigs is interchangeability.Jig design consist of selecting the proper locating and clamping devices and the jig should be robust in order to withstand the cutting forces so the proper material should be selected for manufacturing of the jig. The clamping forces and the cutting force must be calculated and checked and the clamping force must be greater than the cutting force so that the clamping will resist the cutting forces.The aim of this project is to design and manufacture the jig for drilling the holes on the mild steel component so that the position of holes will be at proper position with very less tolerance. The jig is designed for simple vertical milling machine so that unskilled worker will be able to drill the holes without any mistake.The drilling and clamping force are calculated and the design is checked for the safety a proper operation
