When drilling SiCp/Al composites using conventional methods, significant drilling force and high temperature often cause severe edge damage at the hole exit and adhesive wear on the flank face. In this paper, a step drill was designed and the effects of tool geometry and machining parameters during ultrasonically assisted drilling (UAD) of SiCp/Al composites were investigated. The tool geometry parameters include diameter ratio (0.6, 0.8, and 1), length of the first step drill (0 mm, 3 mm, and 6 mm), and point angle. As well as machining parameters such as spindle speed, feed rate and ultrasonic power supply voltage (which determines the amplitude of ultrasonic vibration). This paper focuses on the effects of tool geometry and machining parameters on drilling force, temperature and plasticity of the aluminum matrix, and then explores their combined effects on edge damage and adhesive wear. The results show that the diameter ratio and length of the first step drill are the primary factors influencing drilling force and temperature. The machining parameters have a limited effect on the drilling force but a larger effect on the drilling temperature. An appropriate drilling temperature enhances the plasticity of the Al matrix, reducing edge damage and adhesive wear. The experimental results show that when the thickness of SiCp/Al composites workpiece is 4 mm and the step drill with a diameter ratio of 0.8 and a length of a first step drill of 6 mm is used for drilling, the edge damage at the hole exit and the tool adhesive wear are the least.

Drilling experiments using the tool-foil measurements show that, along the main cutting edge, the drill center has a higher temperature than that of the outer corner. With increasing drilling depth, the temperature difference along the main cutting edge gradually decreases. Moreover, adhesion-dominated tool wear has changed the cutting edge temperature, leading to higher temperature rise in the middle and outer corner regions along the cutting edge than at the drill center.

While the approach is practical, it does not account for the effects of thermal accumulation and potential issues that may arise from successive layer printing after single track optimizations. This, in turn, highlights a need for evaluation of melt pool characteristics through integrated single and multi-layer analysis. The present study investigated the printability of Ti6Al7Nb alloy for biomedical applications by analysing the outcomes based on the alloy's laser-matter interactions. This was achieved by varying the laser power and scan speed between 300 and 400 W and between 1900 and 2300 mm/s, respectively. The adopted framework investigates the interdependence between the laser power and scan speed and their effects on the microstructure and defect formation across single tracks, single layers, and cubic samples. It is shown that the linear energy densities (LED) of 0.184 J/mm &amp; 0.181 J/mm produce the best single tracks. During layer formation, 0.184 J/mm LED yielded the lowest single layer surface roughness (R_a) of 7.49 ± 0.56 μm and relative density of 99.3 %, comparable to those obtained from 0.181 J/mm of 7.64 ± 0.22 μm and 99.1 %, respectively. X-ray diffraction (XRD) patterns and microscopy investigations also indicated that the microstructures formed at an LED of 0.184 J/mm were characterized by few defects and a coarse grain structure. This was attributed to the improved melting, reduced presence of spatter, and prolonged solidification times at this process parameter. The tensile strength tests revealed that stress-relief treatment at 650 °C led to an increase in ultimate tensile strength (UTS) (1195 ± 5.62 MPa) and a decreased elongation to an average of 4.60 % owing to the fine <em>β</em> dispersions. Post subsequent annealing, the UTS decreased to 1081 ± 41.5 MPa while the elongation increased to 5.45 %, which is considered unfavourable for biomedical applications. This observed behaviour was probably influenced by factors such as the presence of grain boundary <em>α</em> (GB _<em>α</em>) and microstructural size. The findings from this study demonstrate that the employed methodology enables a thorough investigation of the optimized tracks as the number of layers is increased. Furthermore, it provides insights into the microstructural manipulation of the alloy during heat treatment, which will greatly assist in improving the mechanical properties.</div></div>","PeriodicalId":16148,"journal":{"name":"Journal of Manufacturing Processes","volume":"150 ","pages":"Pages 111-128"},"PeriodicalIF":6.1,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144313552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, limitations in workpiece stiffness and supporting equipment can cause deformation and abrupt reflection, deteriorating drilling-induced defects. To solve this problem, ultrasonic vibration assisted drilling (UVAD) has shown positive effects on enhancing hole quality. This paper proposed a dynamic thrust force prediction model for UVAD process of thin-walled CFRPs and analyzed the delamination damage. Firstly, the model introduced cutting ratio to establish the relationship between thrust force in UVAD and conventional drilling (CD). Subsequently, the force modeling of CD was segmented into two main stages including drill-in stage and drill-out stage. This modeling was developed based on dynamic feed rate, critical thrust force model and energy conservation law. The accuracy of the predicted thrust force is verified through UVAD experiments of thin-walled CFRP. Results demonstrated the average prediction error for the maximum force across all stiffness levels is 5.43 %, while the average error percentage for the reflection force in 1.2 mm and 1.4 mm workpiece reaches 17.10 %. The predicted and measured results show reasonable agreement for lower stiffness CFRPs. Furthermore, a satisfactory correlation was observed for higher stiffness workpieces except exit stage. Additionally, increased workpiece stiffness and ultrasonic amplitude, along with supported conditions contribute to reduced delamination which is primarily influenced by the reflection effect and force.

Conventional metal bump preparation processes usually rely on complex lift-off techniques, which not only increase the complexity of the process steps, but also face operational risks and are difficult to meet the demands of smaller pixel sizes and pitches. To this end, this study proposes an innovative approach using photoresist bumps instead of conventional metal bumps for the electrical connection between Micro-LEDs and driver substrates. By customized conductive photoresist as a conductive medium and combined with a proven photolithography process, it is possible to accurately prepare photoresist bumps to a predetermined position on the driver substrate without the need for a complex metal deposition process.
