Abstract

The manufacturing industry in Indonesia is growing rapidly. The development of the manufacturing industry makes consumer needs for manufactured products increase. One of the most commonly used automotive manufacturing products is Rotor Sensor. Rotor Sensor is one part in the ABS (Antilock Brake System) braking system in motorized vehicles. In the process of making Rotor Sensor products there are finishing processes, namely turning process on CNC lathe machines. This turning process requires a supporting device, a jig. Jig is one of the equipment holders of objects one to another to make the component doubling accurately. Therefore a jig is needed that can speed up the time of machining the Rotor Sensor product accurately according to the standard. Stages in designing a jig are understanding the shape, dimensions, and knowing the characteristics of the engine to be used for its production. To determine the design of the Rotor Sensor jig, three designs are made with different clamping systems. Calculation of cutting force and shear force is carried out to ensure that one stopper pin can hold the Rotor Sensor on the jig properly. Based on the results of the Rotor jig design the sensors for the turning process on the CNC lathe machine are produced jigs that can complete product machining within 34 seconds. The results of the turning process can be formed according to the standards used for Rotor Sensors with the average test producing acceptable products.

Abstract

PT. RPC Indonesia produces pipes using the filament winding method. The pipe has shipping standards to ensure it reaches its destination safely, so a packing spacer is made as a pipe safety in the shipping process. Currently, the process of making packing spacers is using the hand lay-up method. This is deemed less effective because of the lengthy manual manufacturing process with poor results, and because it takes workers who only focus on making packing spacers. Therefore, a mandrel that functions as concrete was designed to transfer the hand lay-up process to the winding process using a filament winding machine for the production of packing spacers. The Ulrich method is used in the mandrel design process for packing spacers, starting from the requirements, making alternative design concepts, selecting design concepts, and realizing the design. Based on the results of the design concept, the selected design concept is design concept 2. Next, the process of fabrication and testing of the mandrel and the output produced by the mandrel are carried out. It was found that the mandrel was able to produce 18 pieces of DN100 pipe packing spacers in 8 hours. The output or packing spacers produced from the production process with a mandrel using a filament winding machine are able to withstand a load of 3008 kg. The total budget for making mandrels is Rp. 5,847,000. In future research, it is expected to add a silicone filament separator component that is resistant to high temperatures so that the fiber does not slip due to the presence of resin.
