Abstract

This research investigates the measurement error on Wire EDM cutting products to find the pulse current's problem-solving. One of the machining parameters that affect the precision of Wire EDM is the magnitude of the current. The experimental study carried out by using the pulse current started from 4-Ampere up to 8-Ampere as the research parameters. A chamfer dimension on 6061 Aluminum alloy was investigated with the gd&t method with ISO 5459 and ISO 1101 standard. Statistic method applied and processed on Minitab with Shapiro-Wilk parameter for normal distribution. These experimental studies have a normal distribution that finds the phenomena of 8-Ampere of pulse current generate a large measurement error. Furthermore, in these experimental studies, the usage of a Profile Projector generates a massive measurement error, up to 64.5% compared with CMM. A strong commitment to calibrate the Profile Projector up to date to maintain the machining quality.

Abstract

This research complements the shortcomings of PLTB, namely by adding a Monitoring System to the Wind Power Plant at Batam State Polytechnic. By addition of sensors, installations, and a control panel containing instruments for monitoring wind conditions, Savonius turbine rpm, and pico-generator output electrical characteristics. The method used is conventional, starting from mechanical design, program development, and installation to testing. This study's preliminary results indicate that wind at the PLTB Polibatam location is not continuous. It does not occur, even though the maximum wind speed can reach 8.9 m / s. The implementation of the savonius-type wind turbine in this study can generate electricity around 87.83 kW / week or about 0.61 kW / hour.
