Virtual Simulation Teaching Platform Construction and Prac-tice of Online Inspection of Part Geometric Precision//YANG Zeqing， WANG Chunfang， LIU Libing， CHEN Yingshu， PENG Kai

Abstract To improve the practical teaching effect of the precision instruments and mechanical manufacturing technology， taking the practice teaching of the specialty of measurement technology and instrument in Hebei University of Technology as an example， the problems and reform needs of practice teaching were analyzed， and the virtual simulation teaching platform of the typical disc parts geome-tric precision online inspection process was constructed. Through four years of practical teaching experience， the system has gradually improved， and the actual practice demonstrates that the virtual simulation teaching platform has reasonable module settings and clear objectives， which is in favor of cultivating students’ complex engi-neering problems analyzing and solving ability， and the ability to use modern tools. It achieves good practical effect and plays a good demonstration effect in the process of deepening practical teaching reform.

1 精密儀器虚拟仿真教学平台建设的必要性

精密仪器与机械制造技术是高等学校测控技术及仪器专业所设置的一门主干专业课，是研究仪器生产和装配工艺过程精度保障的一门课程。该课程实验教学环节重在培养学生精密零件几何精度在线检测及误差分析能力，启发学生从检测工艺角度不断改进精密零件及仪器零部件精度，为后续专业综合实践奠定基础，对培养从事精密仪器检测工艺分析与精度控制人才具有重要作用[1]。

随着新工科、新技术不断涌现，实践教学体系需要紧跟新技术的发展，不断进行丰富和扩展。但是由于受到场地及资金等限制，如高速高精密数控机床动辄百万元，工业4.0智慧工厂需要较大场地且价值不菲，先进高端实验设备难以进入专业实践教学[2]。……
