Abstract

To support the creative economy, creative ideas are needed which are then transformed into concrete reality. One of the concrete creative ideas is art craftsmen, for example, painting, sculpture, three-dimensional art, sculpture and many more. The promising craft today is the souvenir craft, which has various forms and functions. In this research, the authors specialize in the craft of engraved souvenirs where most of these craftsmen still work on their crafts using conventional media. The purpose of this research is to design and manufacture a prototype CNC Laser Engraver machine with a microcontroller with wireless data communication which is expected to help improve the quality of the production of souvenir craftsmen. The method used is an experimental method in the form of designing, manufacturing and testing the mechanical work of each linear axis of the CNC Laser Engraver machine. With this research it is hoped that a control system scheme for a prototype CNC Laser Engraver machine can be obtained, to be applied to a real CNC Laser Engraver machine. From the results of testing this machine prototype, some data was obtained, namely a machine with three axes of motion, a microcontroller for wireless communication, a laser module with a diode capacity of 1000 mW and a maximum work area of 38 mm x 38 mm x 20 mm, which can help small industries and businesses. small and medium enterprises in the production process of various forms of creative carvings for various materials

Abstract

A Variable Speed Drive (VSD) is a device that regulates the speed and rotational force or torque of mechanical equipment. VSD improves efficiency by allowing the motor to operate at the ideal speed for each load condition. In many applications, VSD reduces the electricity consumption of the motor by 30-60%. The energy-saving potential of electric motors is significant as motor systems account for more than 60% of the power consumed by industries. It is due to these advantages that VSD can be used to control the speed of compressor motors, thereby enhancing the performance of the compressor. A compressor motor is a device that compresses air and increases its pressure. To compress air, the compressor requires a driving force, and one of them is the motor. When the output air pressure of the compressor exceeds a certain value, the relief valve will open automatically, allowing the air to remain in the tank even when the motor is still running. During compressor operation, the motor is always started with a high starting current, resulting in high power demand. Therefore, control of the compressor motor is necessary.
