Abstract

A Shaft has been widely used in machinery construction, transmitting power from one component to another. Firstly, the shaft must be calculated for its safety factor before being used for the actual application. In this study, the specimen used for testing was ST 41 material. The safety factor is essential for engineering design, used to evaluate that machine elements' system is guaranteed safety with minimal dimensions. The way to nd the safety factor of this test tool is to use actual calculations and simulations on the Solidworks software. The value of the safety factor obtained from the calculation will be compared with SolidWorks software's simulation results. The results obtained in a calculation analysis for the actual stress of 6,65x106 N/m2 and the safety factor of 55, while for the actual stress (von Mises) in a simulation of 6,8x106 N/m2 and its safety factor of 54. After validating the data, there is a difference of 1.1% for the actual stress and 0.9% for the value of its safety factor.

Abstract

The research tested the effects between feeding and surface roughness on shaft of steady rest which will be worked in CMZ T-360’s lathe machine. Material of St.60 was turned into shaft of steady rest in 2 CMZT-360’s machines with several of feeding like 0.045, 0.056, 0.068, 0.079, 0.90 and 0,102 mm/rev. Then the work piece was tested the surface roughness of the work piece with using roughness tester and being seen the shape of the surface with using photo macro. The result of the roughness’s test showed that CMZ-T360’s lathe machine could reach Ra 1.55 µm until 4.79 µm with several of feeding. The work piece would be assembled in steady rest and being used to support 58 kg weigth in 2 hours to know the effect of surface roughness. After testing on steady rest, would be done photo macro on the specimen to make easy on visual analysis. From the data which is obtained can conclude that feeding variation which used on this research not so affecting the quality of surface roughness of the workpiece, the value of surface roughness that resulted from this research is mostly N8 (3,25 µm- 5,29 µm) and only a few that valued N7 (1,55 µm-2,53 µm) . The second conclusion is the surface roughness which quickly wornt-out after assembled at steady rest is the rough surface (4,79 µm become 3,84 µm) compared with the smooth surface (2,23 µm become 2,03 µm).

Abstract

This final project makes a device that produces electrical energy by utilizing waste heat from injection machines. The waste heat of the injection machine is converted into electrical energy using a thermoelectric. This device consists of an aluminum heatsink, aluminum plate, thermoelectric, MDF wood planks, engine gasket, and thermal paste. The heat generated by the injection machine is received by the hot side heatsink, then 4 units of the thermoelectric and the cold side heatsink. Thermoelectrics are arranged in series. The output from the thermoelectric is connected to a multimeter to test the amount of voltage and current generated. The number of thermoelectric-based equipment made of 2 (two) pieces and assembled in series. The test was carried out using an open circuit and a closed circuit with a load using a 1 watt LED lamp (Ω 55 Ω). The open circuit test results show that the largest voltage is generated at 10.80 volts with a hot side temperature of 108C and a cold side temperature of 64˚C. The results of the closed circuit test show that the greatest voltage produced is 2.64 volts with a hot side temperature of 108 C and a cold side temperature of 62 C. When thermoelectric based equipment is given a load, the voltage decreases because the voltage is divided into the given load. This equipment can be applied to turn on as many as 5 lamps with a power of 1 watt each which supports production activities in the injection workshop.
