This study presents the development and validation of a mechanistic force prediction model tailored for end milling on a 3-axis CNC milling machine (GMS 800). The model incorporates cutter geometry, process parameters, chip thickness variation, and tool engagement to compute instantaneous and average cutting forces in the tangential, radial, and axial directions. Force coefficients were determined experimentally through controlled calibration tests across a range of spindle speeds, feed rates, and milling strategies (up and down milling). The model was validated through comparison with experimental force measurements, showing strong agreement, particularly in the dominant feed (Y) direction. Six different test cases were analyzed to evaluate the model’s accuracy and robustness, with results demonstrating that the predicted forces closely matched the measured data under various conditions. Minor discrepancies observed in the X and Z directions were attributed to unmodeled dynamic effects and tool runout. The model also enabled estimation of cutting torque and power, providing additional insights into machining efficiency. This research contributes a practical and reliable tool for force prediction in CNC milling, which can be used to optimize cutting parameters, minimize tool deflection, and support intelligent process planning.

The welding of HSSs often leads to cold cracking phenomena due to factors such as high carbon equivalents, hydrogen diffusion, etc. Cold metal transfer (CMT) welding is an innovative alternative to conventional gas metal arc welding (GMAW) and offers advantages such as lower heat input (Q), reduced distortion, and lower spatter. However, optimizing CMT parameters for welding HSS joints remains a challenging task. This research aims to optimize CMT welding parameters for HSS DP1000 steel joints with a thickness of 1 mm, employing two different welding speeds (40 cm/min and 50 cm/min). The mechanical properties (microhardness, tensile test with fractography, and bending test) and the microstructural properties were analyzed and compared. Also, a high-speed camera and synchronous electrical signal acquisition device were used to examine droplet transition characteristics. Microstructures in the base material (BM) comprise martensite and ferrite while with higher heat input, the heat-affected zone (HAZ) has coarser microstructures. Overall microhardness results indicated a reduction in values at a welding speed of 50 cm/min compared to 40 cm/min. Tensile strength results demonstrated the higher strength of the joint with a higher welding speed. Moreover, no cracks were detected in the bending test for joints with both welding speeds. Consequently, it can be concluded that samples welded at a speed of 50 cm/min exhibit enhanced mechanical properties.</div></div>","PeriodicalId":72251,"journal":{"name":"Applications in engineering science","volume":"23 ","pages":"Article 100249"},"PeriodicalIF":2.2,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144631494","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}

To achieve this, numerical simulations were conducted for the cascade models with three blade shapes of varying thicknesses. The length of the separation bubble, its thickness, and the size of the vortex all decreased with increasing blade thickness. Generated noise was predicted using Curle’s equation, and noise measurement experiments were performed with a similar system to validate the prediction accuracy. The results showed good agreement, and the generated noise was reduced at almost all frequencies with increasing blade thickness. To clarify the reasons for this, the cospectra of the time derivative of the fluctuating pressure on the suction surface were analyzed in detail. The following conclusions were drawn: To reduce the noise generated by a sirocco fan, it is effective to reduce the peak value and broaden the shape of the fluctuating pressure distribution on the blade surface and decrease the vortex size.</div></div>","PeriodicalId":72251,"journal":{"name":"Applications in engineering science","volume":"23 ","pages":"Article 100231"},"PeriodicalIF":2.2,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144211902","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 foundation of this architecture is Robot Raconteur, an open-source control and communication framework that serves as the middleware for integrating robots and sensors from different vendors.

The major components in the architecture include part slicing, robot motion planning, part metrology, in-process sensing, and process tuning. The current implementation is based on Motoman robots and Fronius weld controller, but the approach is adaptable to other industrial robots and weld controllers.

The resulting equations effectively capture both local and global effects of applied loads, providing a more accurate representation of substrate behavior in heterogeneous, anisotropic, and non-uniform systems. The validity of the proposed model is verified through comparisons with established theories, demonstrating its precision and broader applicability to complex structural scenarios.

Both plain spiral fins (PSFs) and CSFs are examined. The PTPA is the main geometric parameter of interest in this study. We investigated CSFTHXs with a 19.05 mm outer tube diameter, a fin density of 5 fins per inch (equivalent to a fin pitch of 5.08 mm). The selected peak-to-peak amplitude (PTPA) values—2.5 mm (low), 3.5 mm (medium), and 5.08 mm (high)—cover a representative range commonly used in industrial applications. The results indicate that variations in the PTPA have an insignificant effect on the Colburn factor, suggesting minimal influence on heat transfer performance. However, the PTPA has a significant effect on the friction factor, with higher PTPA values resulting in increased pressure drops. The fin factor, defined as the ratio between the percentage increase in the convective heat transfer coefficient and the corresponding percentage increase in pressure drop, is used for the investigation. For the air frontal velocities above 2 m/s, the fin factor of the CSF with a PTPA of 2.50 mm is higher than those with PTPA values of 3.50 mm and 5.08 mm.
