Abstract

Computerized numerical control (CNC) is one example of advances in automated machine technology. CNC can fulfil high precision and complex product specifications. Industrial CNC milling is still expensive regarding the hardware and software required to operate it. As a result, CNC milling machines are only used by large companies, with only a few mid-sized industries using them. It makes it impossible for medium enterprises to compete with large industries in terms of quality and output. This research aims to develop a CNC that uses an offline Wi-Fi controller based on ESP32 as an application that supports CNC machine work processes for use in small and medium enterprises. In an experiment, the precision of a CNC milling machine equipped with a sliding mode controller (SMC) controller was compared with that of a CNC machine equipped with an ESP-32 Wi-Fi controller. The CNC milling process with SMC control exceeds the tolerance limits in three dimensions based on the results of ten tests, namely length, width, and height or depth. Six values, two in each dimension of length, width, and height or depth, exceeded tolerance limits due to the CNC milling machine's ESP32 Wi-Fi control. Therefore, the CNC with SMC control is more accurate than the ESP32 Wi-Fi control because there are fewer failures with the former. This research has been carried out and provides input for the implementation of SMC, which can be considered in the CNC milling process.

Abstract

Computerized Numerical Control (CNC) is one of the developments of automatically operated machining technology that can support the need for the demand for a product that has a complex shape, high accuracy and can work on objects that cannot be done with conventional machinery. CNC Milling in the industry still has an expensive price, both the price of the hardware and software used to operate the CNC Milling machine. Therefore, CNC milling machines are only used in large industries while the middle and lower industries still use CNC milling machines. This makes medium-sized industries less competitive with large industries in production results, both in terms of speed efficiency and accuracy. then research was carried out in the form of CNC design and design that uses an ESP32 wifi-based Offline Controller as an application that supports the CNC machine work process. This research is an experiential review of comparing the accuracy of CNC milling machines with SMC controllers and CNC milling machines with ESP 32 wifi controllers. From the results of the tests carried out as many as 10 times the milling machining process using CNC with SMC control obtained three values that exceeded the tolerance limit, namely one each on the dimensions of length, width and height or depth. While the results of the milling process using a CNC milling machine with ESP32 wifi control obtained six values that exceeded the tolerance limit, namely two each on the dimensions of length, width and height or depth. So it can be concluded that CNC with SMC control is more accurate because the percentage of failures is less compared to CNC with ESP32 wifi control
