Study on the Amendable Machining System

(1)机械加工表面粗糙度在线测量系统的研制采用接触式和非接触式测头，研制了机械加工表面粗糙度在线测量系统。用该系统测得的表面轮廓与传统的表面粗糙度测量机测得的轮廓一致。(2)二维零件加工误差在机测量系统的研制采用偏差检测法，研制了二维零件加工误差在机测量系统。该系统的测量误差与传统精密三维测量机的测量误差基本一致。(3)修正加工程序（2D）生成系统的开发针对CBN砂轮磨削二维淬硬钢零件的情况，开发了修正加工程序（刀位和加工条件）生成系统。(4)开发的可重磨加工系统（2D）的试验与评价利用开发的可重磨加工系统加工的程序，对用CBN砂轮磨削淬硬钢零件的侧面和内表面进行了重磨。修正后的加工误差由原来的12 μ m减小到4 μ m。

(1) Development of on-the-machine measuring systems of machined surface roughnessOn-the-machine measuring systems of mechined surface roughness have been developed using touch and non-touch probes. The measured profiles by these systems agreed with those measured by conventional surface roughness measuring machine.(2) Development of on-the-machine measuring system of machined errors (2D)On-the-machine measuring system of machined errors of 2-dimensional part has been developed using deviation detecting method. The measured errors by this system agreed with that measured by conventional accurate 3-dimensional measuring machine.(3) Development of generating system of amending machining program (2D)Generating system of amending machining program (cutter locations including machining conditions) has been developed for the cases, where 2-dimensional hardened steel parts are ground by CBN wheels.(4) Tests and evaluations of developed amendable machining system (2D)Hardened steel part, of which side and internal surfaces were ground by CBN wheels, was reground using the program which was processed by the developed amendable machining system. The magnitude of machined error decreased from 12mum to 4mum by the amending machining.
