摘要
针对复杂腔槽多轴数控加工的干涉问题进行了分析研究,进而给出腔槽侧面及底面无干涉刀位的计算方法。对于开口槽侧面边缘处的加工,通过检验侧面边缘与刀轴的干涉而确定粗加工走刀终止条件;对于腔槽底面加工,提出了刀具与底面及相临侧面间干涉的定量计算,并在此基础上根据干涉量一次性修正刀位,生成无干涉的合理刀位。
The paper researched on the generation of interference-free tool position of 5-axis NC milling of grooves with complicated surfaces and presented the grooves＇ side flank and bottom surface interference-free tool position calculation method. To machine the edges of the side flank of an open groove, it determined the flag stop of the tool path during coarse processing by detecting the interference between its side flank and the axis of the tool; to ma- chine the bottom surface of a groove, it proposed a method for calculating the interference between the tool and bottom surface and its adjacent side flanks. According to the interference volume calculated, it carried out a one-time modification of tool position and thus obtained an interference-free reasonable tool position.
