Such lost motion is usually step type and easily compensated for by using the backlash compensation function of NC. However, special cases involve an exponential type lost motion which cannot be compensated for by this method. As a result, machining accuracy of the machine tools is adversely affected. Such lost motion often occurs in large size machine tools with linear ball guides and wiper seals. This paper presents research concerning the generation mechanism and the effective compensation method of the exponential type lost motion by using the existing large size machine tools and the teststands.","PeriodicalId":14336,"journal":{"name":"International Journal of The Japan Society for Precision Engineering","volume":"59 1","pages":"51-52"},"PeriodicalIF":0.0,"publicationDate":"1996-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82047898","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 following experimental results are confirmed : Most anion surfactants appear to be better mediums than cation or nonion surfactants for preventing any adhesion of the minute powders and increasing stock removal. When the silver surface is lapped by using fine aluminium oxide abrasive grains in n-dodecyltrimethyl-ammonium chloride solution (cation) on the glass lapping plate, it is highly resistant to wear, but the rigid glass lapping plate wears out.","PeriodicalId":14336,"journal":{"name":"International Journal of The Japan Society for Precision Engineering","volume":"9 1","pages":"21-25"},"PeriodicalIF":0.0,"publicationDate":"1996-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89839193","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}

In some industries, however, the superiority of the manual operation to fully-automated system is reappraised recently. It is difficult to eliminate manual operations entirely from all manufacturing processes, because sophisticated sensitivity of human operators is indispensable in some kind of process. In this case, the characteristics of the sensitivity should be investigated in detail for utilizing it efficiently. In this research. the authors aim at clarification of manual machine tool operation from the viewpoint of human engineering. Particularly, minute grooving operation with a lathe. in which operational accuracy and speed are dependent upon the perception of the operator, is discussed in the present paper. Firstly, an experimental apparatus “virtual lathe” is newly developed so that analyses may be done under simplified conditions. By using it, the operator gets cutting force, motion of cutting tool, cutting sound, etc. through his own perceptive organs as if he uses an actual machine. Applying the apparatus to the minute grooving, secondly, the skill learning process of six testees is investigated. Obtained conclusions are summarized as follows : The similarity between actual operation and virtual lathe operation is confirmed. The force sensory feedback is effective in improvement of learning speed. The skill acquired relevant to operating accuracy is difficult to lose compared with that relevant to operating speed.","PeriodicalId":14336,"journal":{"name":"International Journal of The Japan Society for Precision Engineering","volume":"20 1","pages":"221-226"},"PeriodicalIF":0.0,"publicationDate":"1996-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81711486","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}

A vibration control system consists of piezoelectric sensors, piezoelectric actuators and a controller. The signals of the tool vibration are detected by the piezoelectric sensors and modified into the rectangular waves which are applied to the piezoelectric actuators to drive the tip of a boring tool. A cutting state recognition system which is based on an artificial neural network is also proposed. In this system, power spectrums of the signals detected by piezoelectric sensors are calculated to identify the cutting state. The input data of the artificial neural network are normalized by the maximum value of the power spectrum. The normalized pattems are utilize to identify whether the cutting state is stable or unstable. The vibration control system and the cutting state recognition system have been examined in cutting tests. The test results verify the effectiveness of the proposed systems for practical application.","PeriodicalId":14336,"journal":{"name":"International Journal of The Japan Society for Precision Engineering","volume":"48 4 1","pages":"201-205"},"PeriodicalIF":0.0,"publicationDate":"1996-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89162375","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}

Second, the trial solution is improved by line re-balancing in the joint area of partial problems to search for a satisfactory solution.

This method provides better grinding performance compared with grinding under fluid. The compressive residual stress of workpieces ground using our method are higher and deeper compared with CBN grinding under fluid, and the material strength of workpieces is higher even under high-efficiency grinding.","PeriodicalId":14336,"journal":{"name":"International Journal of The Japan Society for Precision Engineering","volume":"12 1","pages":"187-192"},"PeriodicalIF":0.0,"publicationDate":"1996-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87261904","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 tool wear images were obtained from an ITV camera with magnifying and lightening devices, and were analyzed using image processing techniques such as thresholding, noise filtering and boundary tracing. Thresholding was used to transform the captured gray scale image into a binary image for rapid sequential image processing. The threshold level was determined using a novel technique in which the brightness histograms of two concentric windows containing the tool wear image were compared. The use of noise filtering and boundary tracing to reduce the measuring errors was explored. Performance tests of the measurement precision and processing speed revealed that the direct method was highly effective in intermittent tool wear monitoring.","PeriodicalId":14336,"journal":{"name":"International Journal of The Japan Society for Precision Engineering","volume":"27 1","pages":"112-117"},"PeriodicalIF":0.0,"publicationDate":"1995-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74653808","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}
