Design and Implementation of DSP Based Cross-Platform Material Scratch Test Control System

Scratch test is mainly used for quantitative measurement of mechanical properties of coating materials in the field of modern materials testing. Advanced materials research have higher accuracy and stability requirements for scratch device but the control system the device mainly use can’t achieve dynamic and fast scratch because of the slow feedback. This paper designed a cross-platform material scratch test control system based on DSP data transmission and multi-axes control technique. System integrates good dynamic response sensors and advanced piezoelectric ceramic feed system, implements multi-axis synchronous control through the motion controller and running state monitoring through the DSP module .Adopting the standard PCI interface and cross-platform software development, the system has good portability.
