摘要
以VMC400型立式加工中心的(Y向进给)伺服系统作为研究对象,通过对系统的分析,依次建立了位置控制器与速度控制器、机械传动机构、数控进给传动系统的力学模型与数学模型,推导出进给传动系统的定位精度数学表达式(半闭环),并对影响进伺服进给给定位精度的相关因素进行了分析和计算。
The VMC400 type vertical machining center （Y feed） servo system as the research object, through the analysis of the system, which established the mechanical model and mathematical model of position controller and speed controller, a mechanical transmission mechanism, CNC feed drive system, the positioning accuracy derived feed drive system are derived, and the （Ban Bihuan） related factors into the servo feed to the positioning accuracy is ana- lyzed and calculated.
