VALVE GRINDING AUTOMATIC SYSTEM BASED MICROCONTROLLER

Abstract

Valve Grinding Automatic System Based Microcontroller is an innovation designed and created to be able to work by converting electrical energy into rotational motion and is also able to overcome mechanical difficulties in regulating manual cleaning movements by hand. The Valve Grinding Automatic System Based Microcontroller provides three choices of rotational speeds of 1500 rpm, 2000 rpm and 2500 rpm with each speed requiring a cleaning time of 3 minutes, 2 minutes, and 1 minute. Testing this tool is done by checking the results of each cleaning from the results of different speeds. From the test results using diesel, it is known that the valve cleaning results do not leak and have met the standards. The stages used in the development of the Valve Grinding Automatic System Based Microcontroller are planning, observation and literature study, tool design, survey of materials and tools, procurement of tools and materials, tool manufacture/assembly, tool testing, tool revision, tool socialization, acceptance survey and finished. Tool making is done in the workshop of the Department of Automotive Engineering, Faculty of Engineering, Padang State University. The team has also published a prototype of a scientific article regarding the Microcontroller-Based Automatic Valve Grinding System in the Journal of Automotive and Vocational Engineering Education (AEEJ) Padang State University.
