Abstract

A single friction plate clutch is one part of the components in a vehicle that is used to transmit power and rotation from the driveshaft to the driven shaft without slippage. This study aims to compare the results of mathematical calculations with analysis based on finite element methods in the design of a single friction plate clutch such as shaft, spline, friction plate, and spring. The analysis was carried out on the shaft made of S30C, spline made of S30C, friction plates made of steel alloy, and springs made of carbon steel. The component was drawn by Solidworks-17 software and analysed by Abaqus 6.14-5 software based on finite element methods. The study was performed by comparing the sizes of the various elements. A comparison of simulation processes using the stress concept of von-misses was conducted. The results of mathematical calculations with the simulation process were compared, and the maximum deviation was 2.881%. The deviation was considered acceptable. Based on von-misses’ maximum stress, the material was safe to use due to below the yield strength.

Abstract

The aim of the program was community service types of application of science and technology byDatabase Creation and Usage Machine Maintenance and its Equipment at Muhammadiyah Kartasura and Jatinom Klaten as Vocational School to support the practicum process in the Muhammadiyah Vocational School laboratory. The implementation method wasbysynchronize basic inventory, then made a data base application by means of machine tools sticking with barcodes on a laboratory scale. With this activity, its will facilitating the implementation of routines and practicum readiness from time to time. Thus at the same time this will add value to the teaching and learning process atSMK which includes 40% theory and 60% practice manufacture.Through this activity it will also add value to their vocation which will bring the world of education and industry much closer, especially in the field of goods assembling and manufacturing.From observations while working with partners, namely SMK Muhammadiyah Kartasura and SMK Muhammadiyah Jatinom Klaten, the obstacle faced is in coaching on the creation of a data base for the use and maintenance or readiness of tools for practice. The process of creating a database of equipment,usage and conditions,this will support the continuity of the practicum process smoothly. The making of this database will be transmitted and will become provision for students primarily for competence in the areaof manufacturing work or for future entrepreneurship. So it is expected from this process, students and teachers get a new way of learning, useful for students and the existence of the SMK in the future, particularly in learning assembly making and thinking steps to control the underlying equipment. Thus the students have enough competence and adaptive when entering the world of work related to the process design based on data collection and monitoring using technology growing of smartphones

Abstract

AISI 1045 medium-carbon steel is widely used for machining because of its excellent machinability. It balances strength and workability in various manufacturing applications, including machinery parts, gears, mold pins, automotive parts, crankshafts, bolts, and studs. The most significant disadvantage of AISI 1045 machining is that if the cutting parameters are not managed appropriately, it can affect the efficiency of the machining process, which involves tool life and product surface finish at dry cutting conditions. This study aims to determine suitable cutting parameters for AISI 1045, identify the optimum minimum tool wear (VB), and assess surface roughness (Ra). This study used various machining parameters at a cutting speed (Vc) of 35–53 m/min, feed rate (fr) of 0.15, and 0.5 mm/rev at a 1 mm constant depth of cut (DOC). The results showed that a Vc of 35 m/min and a fr of 0.15 mm/rev obtained the lowest average VB of 0.07 mm and Ra of 3.8 µm. This study found that low machining parameters produce high dry-cutting performance. This study provides guidelines for machinists to use appropriate cutting parameters when machining AISI 1045 under dry-cutting conditions at short machining times. In addition, it promotes sustainable machining and prevents air pollution from using coolants (chemical reactions).
