活塞异形外圆数控车床的实验研究与误差分析

摘要

用活塞异形外圆数控车床在不同加工条件下加工活塞，测量活塞的最大径尺寸，研究分析了车床加工原理，梳理了活塞加工过程中微进给系统的工作流程。通过实验数据分析活塞尺寸误差变化规律，找出影响误差变化的主要因素，为相关机床研究者提供一个可供参考的实验依据，也为进一步提高该类型数控机床的性能提供了努力的方向。%A CNC lathe is applied to machining shaped piston contour in different conditions ,the machining principle of lathe and the working process of micro-feed system are analyzed ,and the maximum diameter sizes of pistons are measured .Through the analysis of error variation of experimental data ,the main factors affecting error are identified .This work may provide some reference for researchers to improve the performance of this type of CNC machine .
