Then the control system for boring the non-cylinder pin hole of piston was developed, whose main function modules including displacement ( detection,) temperature detection for thermal deformation compensation, constant current power and ( central) control unit. 然后研制了活塞异形销孔加工控制系统,包括主控、位移检测、热变形补偿温度检测和恒流源驱动等功能模块。
