The method of error compensation is presented here in a manner that is accessible to the undergraduate engineering student. A homogeneous transformation matrix (HTM) model quantifies the geometric errors of a machine tool, which can be compensated for in software. The mathematical treatment is reduced to only essential elements to emphasize physical understanding. A key feature of this presentation is the application of the model to a three-axis milling machine. This illustration enables the undergraduate student to grasp the concept with ease. Another feature is that the entire model is developed from first principles, which does not require the student to invoke any empirical relationships. Three solved numerical problems illustrate the application of the model to practical situations. Information provided here may be used by the teacher as a template to introduce this subject at the undergraduate level.</p></div>","PeriodicalId":34573,"journal":{"name":"Advances in Industrial and Manufacturing Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666912922000186/pdfft?md5=84b5f6732793258fb5389bd95c424871&pid=1-s2.0-S2666912922000186-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49551367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this sense, the objective of this work is to analyze the influence of the parameters in bead and multi-layer wall geometries fabricated by the Cold Metal Transfer process to select the configurations that result in the best deposition control. The study was carried out in four steps: (i) deposition of single beads on plate, varying wire feed speed and travel speed that would result in stable and sound beads; (ii) deposition of five layer walls, considering both unidirectional and bidirectional path strategies, with and without stops between layers; (iii) deposition of ten and twenty layer walls, refining deposition parameters; and (iv) deposition of a one hundred layer wall, with the best parameter configuration among the previously tested, with bidirectional continuous strategy. The results showed that the geometry produced with a mean current of 62 A and torch travel speed of 8 mm/s along each layer and 24 mm/s on the transition between layers generated the best results, considering the natural cooling conditions. Also, the bidirectional path deposition presented the most regular geometries, when compared to the unidirectional strategy.</p></div>","PeriodicalId":34573,"journal":{"name":"Advances in Industrial and Manufacturing Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666912922000320/pdfft?md5=5d916c4020dc1e716750e29971c7b163&pid=1-s2.0-S2666912922000320-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47973915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their achieving scores can be optimized by adjusting the 3D printing process parameters. The effect of six (6) 3D printing control parameters, i.e., raster deposition angle, infill density, nozzle temperature, bed temperature, printing speed, and layer thickness, on the aforementioned quality indicators is investigated herein.

Experimental data were processed with Robust Design Theory. An L25 Taguchi orthogonal array (twenty-five runs) was compiled, for the six control parameters with five levels for each one of them.

Laser Powder Directed Energy Deposition (LP-DED) is an AM process providing large scale manufacturing of thin-wall microchannel heat exchangers. Successful industrialization of the LP-DED process requires critical quantification and understanding of the metallurgical, geometric, and process limitations. Specifically, understanding the as-built surface texture, inclusive of roughness and waviness, is significant due to its effects on the friction factor and pressure drop within a heat exchanger. This experimental study completed a design of experiments (DOE) to determine the critical build parameters that impact surface texture for enclosed thin-wall samples. This study summarizes the characterization work of the LP-DED process for 1 mm enclosed walls with an Fe–Ni–Cr (NASA HR-1) alloy. The LP-DED parameters including laser power, powder feedrate, travel speed, layer height, and rotary atomized powder feedstock were modified in the experiment. An evaluation of the DOE samples and resulting surface texture is provided along with conclusions from these experiments. Results indicate that 3D areal and 2D profile (directional) surface texture is estimated by 2x the powder diameter that becomes captured or partially melted on the trailing edge of the melt pool. The fine powder showed a higher sensitivity to parameter changes but resulted in a higher density material and 23% reduction in roughness. Surface texture was also shown to vary between closed channel shapes (internal) due to ricochets, recirculation, and higher volume of powder available to bond compared to external (outer) surfaces. The understanding of the LP-DED process as-built surface texture is essential to fluid flow applications such as heat exchanges and can modify performance for enhanced heat transfer or can be a detriment to pressure drop.</p></div>","PeriodicalId":34573,"journal":{"name":"Advances in Industrial and Manufacturing Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666912922000149/pdfft?md5=6c1ac8ded27688463ca376edf833d901&pid=1-s2.0-S2666912922000149-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45231920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Binary polymer blends have quite commonly been used over the past few decades. Recently, researchers have shifted their focus towards ternary polymer blends and this study aims to investigate a ternary polymer blend system consisting of low-density polyethylene (LDPE), polystyrene (PS) and polymethyl methacrylate (PMMA). The LDPE/PS/PMMA blend was processed by melt blending using a twin-screw extruder. The effects of the extrusion process parameters (i.e., screw speed and barrel set temperatures) and the blend composition on the mechanical, rheological and thermal properties of the polymer blend and the degree of crystallinity of the LDPE matrix were studied. Three different screw speeds (i.e., 50 rpm, 100 rpm and 150 rpm), two different barrel set temperatures (i.e., 200 °C and 220 °C), and two different component mass ratios (i.e., 70/10/20 and 70/20/10) were studied. The results showed that the tensile properties of the LDPE/PS/PMMA blend were significantly influenced by its microstructure. Yield strength and Young's modulus decreased at first and then increased with increasing screw speed. The blend processed at a barrel set temperature of 220 °C was found to have better tensile properties than the blend processed at 200 °C. Furthermore, the blend with a PS content of 10 wt% possessed better tensile properties than the blend with a PS content of 20 wt%. Regardless of the blend compositions and the process settings, the LDPE/PS/PMMA blends reported better mechanical properties than those of pure LDPE with a Young's Modulus of 240 MPa and a yield stress of 10.47 MPa. The rheology of the blend was also significantly affected by the process parameters and the blend composition. However, different process parameters and mass ratios did not indicate a significant influence on the melting temperature (around 109.5 °C) and the degradation initiation temperature (around 252.3 °C) of the LDPE/PS/PMMA blend, but both the melting temperature and the degradation initiation temperature of the ternary blend were found to be slightly lower than those of pure LDPE. The degree of crystallinity of the LDPE matrix was also affected by both the screw speed and the barrel set temperature. The results revealed that, better mechanical properties can be achieved by blending PS and PMMA with LDPE without significantly affecting the thermal properties compared to those of pure LDPE.</p></div>","PeriodicalId":34573,"journal":{"name":"Advances in Industrial and Manufacturing Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666912921000374/pdfft?md5=41c044355ea66f5ea95f356b5e83bd14&pid=1-s2.0-S2666912921000374-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42861233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
