The performance of TMDs is highly dependent on the correct dimensioning and selection of the most suitable damping materials, which cannot be determined through trial and error, making modeling essential. This study presents a new TMD design for milling tools, optimized through Finite Element Method (FEM) modeling. The FEM analysis allows for maximizing damping efficiency through the precise selection of optimal dimensional parameters tailored to the specific tool geometry.

In longitudinal turning, the spindle motor power was found to be sensitive to the level of flank wear, which can be used for tool wear monitoring. Reliable cutting force prediction from spindle motor power (air cutting power + net cutting power) is also shown. In face turning, the tool exit time in the spindle motor power signal was found to be sensitive to tool geometry changes due to wear, suggesting that it can be used for tool wear monitoring.

The objective of this work is to determine if positional control is principally possible for trajectory-based latent spaces. Therefore, we investigate how ‘reach’ trajectories that are constrained in the target position map to a latent space that has been derived from functional principal component analysis (fPCA). A multivariate normality test is conducted to analyze the target-constrained position in the latent space, followed by mapping between the latent and Cartesian spaces. Results show that for linear shifts in the target ‘reach’ position, Gaussian modes in the latent space move along a vector in the latent space. Additionally, Gaussian mixtures occur at the target point where different motion styles are chosen for reaching. Results suggest that positional control may prove feasible for the considered type of latent space.</div></div>","PeriodicalId":20535,"journal":{"name":"Procedia CIRP","volume":"134 ","pages":"Pages 431-436"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144291043","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}

Typically, tracing relies on production data from historical relational databases, but these data lack semantic information and integration with the service context of manufacturing processes. A manufacturing knowledge graph (MKG) offers a solution by adding manufacturing semantic information to production data. This paper constructed a PQT model and an MKG database for AM. The PQT model and the schema layer of the MKG originate from the swimlane flowchart. Subsequently, a relational database was mapped to instantiate the MKG, and the natural language model was used to complete it. This integration constructs a PQT model and an MKG database centered on manufacturing resources, events, data, and states. The tracing subgraphs extracted from the MKG database demonstrate that this method effectively traces manufacturing process issues and anomalies. The proposed method provides a viable database and method for PQT in AM, enabling comprehensive tracing of manufacturing processes, identifying quality anomalies, and providing potential cause references for AM experts.</div></div>","PeriodicalId":20535,"journal":{"name":"Procedia CIRP","volume":"134 ","pages":"Pages 544-549"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144290910","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}
