摘要槽轮机构是一种步进间歇运动机构，由于结构简单、制造容易、工作可靠,能准确地控制转角, 机械效率高, 所以在自动和半自动生产线中得到广泛的应用;但槽轮在销轴进出槽轮槽口时加速度大,机构产生较大的冲击,而且随着转速的增加和槽轮槽数的减少冲击加剧，因而不适用于高速运转的情况。本设计以槽数4 、销轮和槽轮中心距33 mm、销轴半径2 mm、铣刀半径2mm 为例，设计槽槽轮机构，并对槽轮的运动特性进行分析。采用CAM技术对槽轮和拨盘进行数控编程，对零件进行工艺分析，确定刀具和切削用量，最后形成NC指令。关键词：槽轮机构 工艺 数控编程 NC1AbstractGeneva agencies is stepping intermittent movement，because of Simple structure、manufacturing easy、reliable，Can accurately control angle, High mechanical efficiency，Therefore, automatic and semi-automatic production line is widely used; But trough round slot in the round pin and out of the acceleration when Passage，Institutions have a greater impact，moreover, with the speed and the increase in the number of slot groove round of intensified to reduce the impact，Thus does not apply to high-speed operation My Design is take 4 to trough, and trough round pin round of 33 mm center distance, pin radius of 2 mm, 2 mm radius cutter for example, Design groove grooved wheel agencies, and the movement of tank rounds analysis. Using CAM technology to dial tank round and NC Programming, Process analysis of the parts, Cutting Tool and determine the amount, finally formed NC
