This SAE Recommended Practice is prepared as a guideline to improve and maintain the quality of remanufactured automotive products. Installation of remanufactured or rebuilt products is often an economical way to repair a vehicle even though they may not fully be equivalent to original equipment parts. Before processing any part, a remanufacturer should determine if the original design and present condition of the core are suitable for remanufacturing, so as to provide durable operation of the part as well as acceptable performance when installed in a vehicle. The remanufacturer should also carefully consider the safety aspects of the product and any recommendations of the original manufacturer related to remanufacturing or rebuilding their product.

Abstract In this work an attempt is made to design and fabricate a low cost dynamometer for measuring cutting forces in three directions in a CNC vertical milling machine. The dynamometer is designed and fabricated to withstand load up to 5000 N along ‘X’, ‘Y’ and ‘Z’ axis. Milling dynamometer developed in this work, consists of four octagonal rings as an elastic member on which strain gauges are mounted for measuring the cutting forces. Suitable materials for the fixture and for the octagonal rings are chosen for constructing the dynamometer. Structural analysis has been carried out to check the safe design of the dynamometer assembly consisting of fixture and the octagonal rings for the maximum loading conditions. Static calibration of the dynamometer is carried out using slotted weight method by simulating the actual conditions. Calibration chart was prepared for three directions by relating load and corresponding strain.

Abstract Machining of materials has received significant consideration due to the increasing use of machining processes in various industrial applications. In machining, the heat generated in the cutting zone during machining is critical in deciding the work piece quality. Lubricants are widely used to reduce the heat generation. Their usage poses threat to environment and health hazards. Hence, there is a need to identify eco-friendly and user-friendly alternatives to conventional cutting fluids. Modern tribology has facilitated the use of solid lubricants such as graphite, calcium fluoride, molybdenum disulphide, and boric acid as an alternative to cutting fluids in machining. Solid lubricant assisted machining is an environmental friendly clean technology for improving the surface quality of the machined work piece.

Abstract Lean approaches are being implemented in various manufacturing facilities across the globe. The application of lean approaches are extended to Body proto build shop to maximize the efficiency of the shop with lesser floor space and optimized equipment. Weld fixture, Weld equipment and assembly tools are the major tools required essentially for proto BIW assembly. This paper explains how the Weld equipment planning was carried out with lean approaches and implemented effectively in proto body assembly shop. The implemented lean concepts are compared with Italy and Japanese proto body build makers to validate the frugal planning of the facility for the said intent. The implemented facility is capable of producing more than a model at a time. Weld parameter selection for weld gun, gun movement to the fixture with minimized change over time and movable weld gun gantry are the lean approaches implemented.

Abstract Cryogenic treatment is an ultra low temperature treatment technique. Effect of cryogenic treatment on properties of ferrous materials and alloys is well understood. Due to which, cryogenic treated materials are being used in various applications. One among them is Electro-Discharge Machining (EDM). In EDM, the replica of electrode is obtained on the work piece, during the process tool also worn out to certain extent. In order to reduce the tool wear rate cryogenic treatment can be applied to the tool material. In this paper, the effect of cryogenic treatment on electrode wear rate of electro-discharge machining for varied pulse ON time (EDM) was studied. The cryogenic treatment was applied to the copper electrode and the microstructure analysis was carried out using optical microscope. EDM experiment was conducted using untreated and cryogenic treated copper as electrode and High Speed Steel (HSS) as work piece. Electrical resistivity was also measured.

Abstract Piston rings are used to seal the cavity formed between the piston and the cylinder in order to allow the engine to operate efficiently. The piston rings wear out due to constant rubbing action with cylinder wall and also have to withstand high temperature. This has lead to the development of new piston ring coatings with good wear properties under increasingly challenging running conditions. To improve the wear resistance of the piston rings several coating techniques are employed. One such technique is Ni-P composite coating which is widely used in the automotive industry. Reinforcement of ceramic particles enhances the tribological and mechanical properties of the coating. The base material of the piston ring used in this study is hardened carbon steel. The main objective is to develop an optimum Ni-P composite coating on piston ring to improve wear and friction resistance.

Abstract The main objective is to Extraction of cellulose fibers using mechanical ball milling process and chemical treatment methods. The fibers are incorporated with an epoxy matrix to make composite plates. Mechanical properties such as tensile strength, flexural strength, and impact energy are evaluated. Ball milling is the mechanical extraction method of producing nano size powder. The increase in milling process results in the chance of occurring nanofibers. The ball milling process is carried out without any chemical treatment process. In chemical treatment methods, three different kinds of treatment are performed namely sodium hypochlorite, sulphuric acid and acetic acid. Using hand layup methods these fibers are incorporated into the epoxy matrix to fabricate composite plates. In my study nanosized fiber is not obtained, only 28 micron fibers are converted into 3-4 microns.
