Abstract: In this paper, a variety of widely used hardware clamp tools were taken as the processing
object, and STM32F103ZET6 was adopted as the core processor of the hardware circuit to design a
human-computer interaction system of automation grinding equipment. Meanwhile, a completed
mechanical grinding platform according to the system was designed as well and grinding automation
equipment was integrated based on embedded hardware clamp tools. The system contains a dynamic
adjustment of the arc grinding algorithm, which can adjust the input parameters dynamically
according to the different arc sizes and shapes. This system will automatically calculate the
interpolation of the movement of the path to complete the automated grinding. Finally, the debugging
result shows that the system is running smoothly and the interpolation is accurate.

Key words: hardware clamp, STM32F103ZET6, arc grinding
