【摘要】：針對空間填充曲線法的網(wǎng)格只具有正則矩形,生成的刀具路徑存在頻繁轉(zhuǎn)向、長度冗長、生成時間長等缺點,提出一種基于空間填充法的刀具路徑生成算法。選用T樣條曲面為造型曲面,生成具有非正則矩形的網(wǎng)格并進行回路的規(guī)劃;用改進的Hamiltonian算法初步生成刀具路徑;用改進的倒圓角算法進行拐角優(yōu)化,獲得最終的刀具路徑。開發(fā)出了基于該算法的仿真系統(tǒng),對算法進行了仿真驗證和實際的加工實驗,結(jié)果表明所提出算法有效可行,生成的刀具路徑長度及生成時間都得到縮短。
[Abstract]:The grid of space filling curve method only has regular rectangle, and the generated tool path has the disadvantages of frequent turning, long length, long generation time and so on. This paper presents a tool path generation algorithm based on space filling method. Using T-spline surface as modeling surface, the mesh with irregular rectangle is generated and loop planning is carried out, and the tool path is preliminarily generated by improved Hamiltonian algorithm. Finally, a simulation system based on this algorithm is developed. The simulation results show that the proposed algorithm is effective and feasible. The tool path length and generation time are shortened.
