The surface ladder effect produced by prototyping principle is analyzed , and the calculation method of the part surface roughness is presented . the selecting method of slice thickness and sintering layer thickness when slicing the cad model and sintering is presented 分析了由于成型原理所產(chǎn)生的制件表面階梯效應(yīng),提出了制件表面粗糙度的計(jì)算方法,給出了cad模型切片時(shí),切片厚度的選取方法。
Modeling surface is approached by stair up of lines in the current lom process , so theoretical manufacturing error and remaining material quantity are greater . the higher precision and lower remaining material quantity are ensured by using the thinner slicing thickness 本文指出現(xiàn)有l(wèi)om方法由于用直線臺(tái)階逼近造型曲面,因而原理加工誤差大,殘留加工量多,必須使用較薄的分層厚度來保證較高的造型精度和較小的殘留光整加工量。
The work of this thesis lays a solid foundation for the integration of cad , capp and rp . the main work may be summ arized as follows : ( 1 ) after discussing all kinds of existing algorithms , this thesis presents a new kind of adaptive slicing algorithm that determines the slicing thickness by comprehensively considering the surface normal and the cross - sectional area . and for the same part , a comparison between the adaptive slicing and the equal - thickness slicing methods is performed 論文所做的主要工作如下: ( 1 )在綜合考慮各種分層算法的基礎(chǔ)上,提出了法線與面積綜合判定法來確定分層厚度的cad模型直接自適應(yīng)分層算法:并針對同一模型對自適應(yīng)分層和等厚分層進(jìn)行了比較,結(jié)果發(fā)現(xiàn):自適應(yīng)分層在精度方面雖然與等厚分層基本相當(dāng),但是其層數(shù)可以顯著減少,所以采用自適應(yīng)分層可使成形效率顯著提高。
