摘　　要：针对高质量的等高线高速加工要求 ,设计并实现了数控加工中、根据刀位面及其Zmap模型计算等高线刀具轨迹的原理和算法 .该算法充分考虑了刀位面Zmap模型的特点 ,能确保刀具轨迹始终处于顺铣状态 ,从而保证了良好的加工工艺性 .算法稳定性好 ,计算速度快 ,并已在商品化软件CAXAAppealed by high-speed Z-constant machining with high quality, an algorithm of generating Z-constant toolpath in NC machining was presented based on the cutter location surface and its Zmap model. It guarantees that the toolpath of climb cutting can be obtained in consideration of the cutter location surface Zmap model features, thus to gain a qualified surface. This method was realized successfully in business software: CAXA-ME, which with satisfying computing speed and stability.
