Design And Development of Ardunio CNC hot wire cutter.

Mechanical Engineering

A wedding without decorations is incomplete. Interior decoration companies should create a group of skilled and creative workers, improve the production skills of workers and offer customers a variety of decoration options. The newest material used for decoration is polystyrene foam. The goal of this work is to create a CNC machine that achieves good results and precisely cuts polystyrene with hot metal. This research also helps solve the problems of cutting polystyrene foam, an often detailed and complex task that can be solved with CNC machine tools. The hardware design requires Bluetooth connectivity, stepper motor control, A4988 CNC screen control and heated iron voltage. Software development involves downloading the GRBL firmware ,generating the G-code with Inkscape software, and connecting the Android app to the CNC machine. The results showed that the best cut of 1 cm thick 2D foam was achieved between 7.4 and 8.5 V.Styro v foam was also tested at the same voltage of 8.5 V but with a different feed rate and 400 mm/min and were found to work best. The 3Dfoam cutting results showed that 8.5 V voltage, 300 mm/min feed and v foam thickness of 10 cm achieved the best cutting hardness or softness compared to others. plastic foams. This shows that the heat produced by the welding metal is directly proportional to the speed of advance
