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":"2025-07-07","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}
