Under the condition that the cutting thickness is less than the critical undeformed chip thickness, the single crystal brittle material is removed in ductile mode. The critical undeformed chip thickness of single crystal brittle materials is not an intrinsic parameter, but a variable related to stress conditions, crystal orientation and other factors. In this paper, aiming at the critical undeformed chip thickness of single crystal germanium, the influence of the changes of crystal orientation, tool rake angle and linear velocity on the critical undeformed chip thickness of single crystal germanium is investigated by means of constant linear velocity single point diamond turning. The experimental results show that critical undeformed chip thickness of single crystal germanium varies in different crystal orientations. Large tool negative rake angle can increase the critical undeformed chip thickness of single crystal germanium. Increasing the linear velocity within a certain range can increase the critical undeformed chip thickness of single crystal germanium, however, excessive linear velocity will worsen the cutting state and reduce the critical undeformed chip thickness. This study provides some references for ductile mode cutting of single crystal germanium and other brittle materials.","PeriodicalId":236529,"journal":{"name":"International Symposium on Advanced Optical Manufacturing and Testing Technologies (AOMATT)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116152965","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}

Therefore, an online laser perforating device is designed. By directly performing 360° laser perforation on the surface of the semi-finished cigarette, the stability of the ventilation rate of the cigarette filter can be effectively controlled and the production cost can be reduced. The application results shown that the use of online laser perforation device, by adjusting the perforation time, quantity and size of the hole, the average pass rate of the filter ventilation rate has increased by 17.3%, and the standard deviation pass rate has increased by 10.8%, which effectively improves the stability of ventilation rate for the filter. The average consumption cost of the materials for every 10,000 cigarettes of a certain brand is reduced by 41.2%, which effectively reduces the cost of cigarettes, and can set the different quantity of perforating holes and the filter ventilation rate values according to process requirements.","PeriodicalId":236529,"journal":{"name":"International Symposium on Advanced Optical Manufacturing and Testing Technologies (AOMATT)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128963779","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 this work, high catalytic and controllably synthesized near-spherical Au NPs with size of sub-100 nm was interestingly employed, meanwhile, a facile in-situ oxidative polymerization was used to composite the Au NPs with the conventional binary PANI- TiO2. Analysis and characterization of the structures, compositions, and the gas-sensing performances of the designed ternary ammonia gas sensor were systematically explored. The results show that the Au and TiO2 NPs were evenly distributed among the PANI fibrous networks, favoring the construction of the practical gas sensors. Besides, the gas sensor with 1 wt% of Au and 20 mol% of TiO2 dispersed into PANI showed an excellent gas-sensing performance: the response and recovery rates of the sensors respectively reach 32 s and 111 s to 100 ppm concentration of ammonia at room temperature, and the response value approach to 123%, which is approximately 1.9 times and 1.2 times higher than the pure PANI and PANI-TiO2. Furthermore, the designed gas sensors exhibited significant stability, selectivity and response-concentration linearity (correlation coefficients R2=0.9984). It is expected that our concerned and designed ternary gas sensors may find great potential applications such as in flexible wearable devices and the medical health monitors.","PeriodicalId":236529,"journal":{"name":"International Symposium on Advanced Optical Manufacturing and Testing Technologies (AOMATT)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127729801","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}

Wumingshan in Daocheng, Sichuan of China. The main scientific purpose for developing this coronagraph is to investigate the morphology and dynamics of low-layer coronal structures before and during solar eruptions by observing at a float altitude of about 30 km from 1.08 Rsun to 1.5 Rsun at white light wavelength (centered at 550.0 nm, bandwidth 5 nm). The instrument is an internally occulted Lyot coronagraph developed by Yunnan Observatories in collaboration with Shangdong University (in Weihai) and Changchun Institute of Optics, Fine Mechanics and Physics. The coronagraph was designed with scattered light intensity level of better than 1×10-5 Isun in the inner field of view. A filter wheel system with linear polarizers and an sCMOS camera provided polarization and total brightness images of size 2048 x 2048 pixels. The first successful results were taken on February 27, 2021 in the Daocheng site. This coronagraph experiment obtained coronal images only showing obvious coronal structures very near limb. Furthermore, during the end of March and early April, after improving the polarizer filter system, higher-quality coronal images with pB coronal structures appeared in the full field of view were obtained in our ground-based experiments. Comparison between our results and the other coronal data in the world are discussed. The success of the 50 mm coronagraph in ground experiments is a milestone for us to develop the next-generation large-aperture coronagraph, as well as for future near space projects.","PeriodicalId":236529,"journal":{"name":"International Symposium on Advanced Optical Manufacturing and Testing Technologies (AOMATT)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126796577","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}
