弧面凸轮廓面非等径加工的刀位控制方法（Cutter Location Control Method for Unequal Diameter Machining of Globoidal Cam Surface）
弧面凸轮 非等径加工 法向误差 刀位优化
2010/12/29
刀位补偿法是非等径加工弧面凸轮廓面最常用的方法，提出了刀位补偿法法向误差计算的方法和一种刀位自适应补偿优化算法，即对于任意凸轮转角，以最大法向误差最小为目标函数，进行刀位优化，寻求对应的最佳补偿点和补偿量，使刀位根据加工误差自适应地柔性补偿。通过实例验证了法向误差计算式的有效性，并得出了滚子和刀具的半径差是最佳补偿量，而最佳补偿点位置并不固定的结论，结果表明所提出的刀位优化算法正确有效，可显著减小...
从确定设计技术参数、设计技术路线、关键结构设计计算等方面研究了全自动植物纤维餐饮具除边机。采用气缸驱动回转盘间歇转动的五工位设计、行星齿轮布置结构、柔性仿形除边刮刀等装置，实现制品在转盘公转换位和自转运动中完成全自动除边过程。应用Pro/E软件对除边机整机三维实体进行模拟。工作循环采用全自动闭环反馈控制，并在样机上验证控制系统的准确度。试验结果表明，除边机适用于植物纤维餐饮具行业。
针对我国西部地区沙生灌木平茬复壮工作迫切，人工平茬难、劳动强度大、效率低等问题，以及为荒漠化防治实现机械化技术，设计了具有铰接式车体机构的自走式灌木平茬机，实现扭腰式扇面摆动切割作业。提出了人工操纵与机具自适应仿形相结合的纵横向仿形收割沙生灌木方法，并对柠条、沙柳进行了收割试验。试验结果为：柠条漏割损失率小于等于0.8％，割茬破损率为2.9％；沙柳漏割损失率小于等于0.8％，割茬破损率为2.5％，...
