DESIGN OF CHIP CUTTING MACHINE USING QUALITY FUNCTION DEPLOYMENT (QFD) METHOD

Abstract

Chip cutting machine is a tool or instrument used by people who carry out activities or services as traders in the market or at home to meet their daily needs. The early machines used by traders today often experience problems or complaints from them due to their performance, equipment, and supplies when using chip cutters and their components. Chips will be pushed manually into the machine and hands will be in direct contact with the tip of the machine. The purpose of this study is to determine consumer demand for chip cutting machines and to find out how to use the Quality Function Deployment (QFD) method to design machines according to consumer demand for chip cutting machines in order to increase service efficiency to consumers. The data analysis tool in this study uses the House of Quality (HOQ) matrix statistical test with SPSS, while the instruments used for testing are validity tests and reliability tests. Based on the results of the analysis, it shows that consumer satisfaction with the designed machine is positive and significant. The current design results of the machine component that pushes the chips to the semi-automatic arm do not come into direct contact with the chip cutting blade, and the current machine test results show that the design can cut chips with sizes of 2mm and 3mm compared to the initial machine that cut chips with the same size because the blade does not change.
