This is the second report succeeding the first one which mainly dealt with a method of separating thick- and hair-lines using line width and the structural representations of thick-lines. However, this methed can be applicable only to the drawings which keep the JIS drawing rules vigorously, especially about line width. In this paper, we propose another approach which can be applicable to wider range of mechanical drawings. The method mainly utilizes geometrical and topological features and uses line width additionally. The whole algorithm is shown to separate all line elements, i. e., dimension lines, projection lines (temporarily separated), center lines, hidden outlines, leader lines, visible outlines, projection lines (finally separated) and characters, in this order. Some experimental results applied to sample drawings in a book of mechanical drawings are finally shown.","PeriodicalId":14336,"journal":{"name":"International Journal of The Japan Society for Precision Engineering","volume":"102 1","pages":"169-176"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89928386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The influences of bond systems, depths of cut and grinding method (up and/or down cut) on the loading of CBN wheels are examined in detail by measuring the loaded areas,wheel wears and grinding forces. The conclusions are summarized as follows; (1) The loaded area ratio ( loaded area / active surface area) on the vitrified bonded CBN wheel is larger than that on the resin bonded CBN wheel, and the mean area per piece of the loading on vitrified bonded CBN wheel is about 7 times as large as that on resin bonded CBN wheel. (2) Decreasing depth of cut results in a decrease in loading. (3) The loading on vitrified bonded CBN wheel develops more rapidly than that on resin bonded CBN wheel. They are found to be dislodged if loaded areas exceed the limit area (about 0.14mm). (4) The loading of CBN wheels in up cut grinding is less than that in down cut grinding.","PeriodicalId":14336,"journal":{"name":"International Journal of The Japan Society for Precision Engineering","volume":"93 1","pages":"1209-1214"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90584280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although it is desirable for balances that the dimensional errors of springs are eliminated by machining, such a work itself, however, takes engineers much time to correct the dimensional errors. So, the authors propose here a notched springs by which the error rate of displacement can be modified without eliminating the dimensional errors. Following is concluded through theoretical, experimental and FEM analyses. (1) In case of the movement with two circular springs, a notch at around±16deg measured from the position with theminimum thickness is most effective formodification, while the one at the minimum thickness contributes to no modification. (2) In case of that with four circular springs, a notch at around ±3deg measured to the outsides, respectively, from the position with the minimum thickness is most effective for modification, while the one near reinforcing plate shows a few effect.","PeriodicalId":14336,"journal":{"name":"International Journal of The Japan Society for Precision Engineering","volume":"14 1","pages":"346-351"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80887526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is necessary for optimum design to consider mechanical vibration and control. Control designs with mechanical vibrations have two problems : One is a difficulty to input suitable vibration characteristics, the other is an increase in the degree of an equation. Vibration characteristics influence system stability and collocation. This paper describes the analysis system for vibration control using FEM analysis. Mechanical vibrations are analyzed by FEM easily. This analysis system reads modal parameters from FEM output file and control block diagrams are input in dialogue. The analysis results are frequency response, step response and root locus. So it is possible to achieve optimum design for control with a mechanical system having multi-degrees of freedom.","PeriodicalId":14336,"journal":{"name":"International Journal of The Japan Society for Precision Engineering","volume":"130 1","pages":"1315-1320"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81722161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The piloting drills have two short cutting edges and a piloting part on the projection of twist drill point. Experiments showed the following results. These drills improve the roundness at the hole entrance, because the wandering motion of drills can be suppressed by a short chisel edge and has already damped under the effect of a piloting part when the corners of primary cutting edges enter workpiece. In the rotating drill-stationary workpiece system piloting drills produce smaller hole oversize, hole deviation of axis and its scatter at the hole entrance than conically ground drills. Further improvement of them can be obtained by two-step feed, which consists of a very small feed rate and an ordinary feed rate before and after the primary cutting edges enter workpiece, respectively. The improvement of hole accuracy results from small oversize of pilot hole at a small feed rate. Longer piloting part is desirable from the viewpoint of the reduction in hole oversize.","PeriodicalId":14336,"journal":{"name":"International Journal of The Japan Society for Precision Engineering","volume":"2 1","pages":"111-116"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89558302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
