Because the number of rectangle can only be estimated in advance, so probably there is some rectangle exceeding the boundary because of allotting too much rectangle or too fewer rectangles is allotted results in the waste of material
由於自動排樣系統事先只能初步估計待排矩形件的數目，所以自動排樣系統產生的排樣圖可能會因排入的零件太多而使得個別零件超出板材，或因排入的零件太少而使板材無法排滿。Abstract : technology dimensions of work parts always exceed the determined technology dimension limits. but when the work parts are big enough, it is still possible and valuable to modify the work parts " following technology process and technology dimensions, which are respectively called as dynamic technology process ( dtp ) and dynamic technology dimension ( dtd ), to ensure them to be qualified. a mathematical model is proposed which is about how to plan the dtd once the dtp is determined. a software has been written to testify the correctness of the above model. this model will be very useful in the capp and online quality assurance in the manufacturing of precise machine parts
文摘:工件的工藝尺寸在工藝過程中經常會超出許可的范圍，但當這些超差工件仍有足夠的加工余量時，通過修改其後續工藝路線（稱為動態工藝路線）及工藝尺寸（稱為動態工藝尺寸）仍有可能將其加工成成品.本文提出了一種在後續工藝路線確定后如何確定后續工藝尺寸的數學模型，並利用該模型成功地編制出了動態工藝尺寸設計的軟體，且用很多事例驗證了該模型的正確性.該方法可以應用於精密機械零件製造時的計算機輔助工藝過程設計及在線質量保證Based on the analysis of the shortcomings of traditional designs and fan comparability characteristics, the thesis fully studies technical paths of fan parametric design in combination with modern database software techniques, and exploits a complete interactive program system to operate the parametric design for series of centrifugal fans under the support of systematic software of visual basic ( vb ), access and catia. the major research work in the thesis is as follows : 1. ) analyzes and summarizes comparability theory and comparability design of fans ; 2. )
