A cutting machine

Abstract

This application provides a cutting machine, including: a control chip, a solenoid, and a cutting assembly. The control chip is connected to the solenoid, and the solenoid is connected to the cutting assembly. The control chip outputs a pulse width modulation (PWM) signal to the solenoid to drive the solenoid to move, thereby moving the cutting assembly to a cutting position to perform a cutting operation. Before the cutting assembly reaches the cutting position, the duty cycle of the PWM signal increases from a reference duty cycle according to a first preset trend until it reaches a first preset duty cycle, which is the duty cycle that enables the cutting assembly to move to the cutting position. After the cutting assembly reaches the cutting position, the duty cycle of the PWM signal decreases according to a second preset trend until it reaches a second preset duty cycle, which is the duty cycle that enables the cutting assembly to perform a cutting operation.
