The maximum external dimensions of the product are 46.88\u00d716.41\u00d710.91 mm. Its machining tolerance requirements are as follows:<\/p>\n<ul>\n<li>The strictest dimension tolerance of the part is 38.88-0.02 mm, which can be maintained by two times fine milling at the same path.<\/li>\n<li>Other tolerances of \u00b10.03 mm and above can be guaranteed with a single fine milling.<\/li>\n<li>The three sets of +0.015 mm precision holes can be ensured through precision reaming.<\/li>\n<li>Positional accuracy is best achieved by machining the measured hole and reference datum in the same process.<\/li>\n<li>Perpendicularity of 0.02mm can be maintained by machining in the same process as Datum A or using Datum A as the reference.<\/li>\n<li>The flatness of 0.01 requires proper machining parameters. So this finishing machining should employed later in the whole process to minimize deformation.<\/li>\n<\/ul>\n<p>Finally, the product also requires age hardening to release material stress and ensure long-term dimensional stability. Since the product is not big and the material removal rate is less than 80%, a single precipitation heat treatment before machining is sufficient.<\/p>\n<h2>Process Route Comparison for Machining Aluminum Polyhedral Parts<\/h2>\n<p>Comparing the two process routes in the following picture shows that the 3-axis machining solutions require five process procedures, each needing a custom fixture. In contrast, using 3+2 axis machining, supplemented by a 3-axis machine to remove residual material at the joint position, requires only two process procedures and fewer fixtures.<\/p>\n<p>For small batch orders from 50 to 1000, the second machining solution has a significant cycle time advantage. At the same time, it better guarantees the key dimensions by completing them in the same process procedure.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-53349 perfmatters-lazy entered pmloaded\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/two-machining-routes-comparison-of-polyhedral-parts-optimized.jpg\" sizes=\"auto, (max-width: 700px) 100vw, 700px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/two-machining-routes-comparison-of-polyhedral-parts-optimized.jpg 700w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/two-machining-routes-comparison-of-polyhedral-parts-300x297-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/two-machining-routes-comparison-of-polyhedral-parts-150x150-optimized.jpg 150w\" alt=\"two machining routes comparison of polyhedral parts\" width=\"700\" height=\"694\" data-src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/two-machining-routes-comparison-of-polyhedral-parts-optimized.jpg\" data-srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/two-machining-routes-comparison-of-polyhedral-parts-optimized.jpg 700w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/two-machining-routes-comparison-of-polyhedral-parts-300x297-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/two-machining-routes-comparison-of-polyhedral-parts-150x150-optimized.jpg 150w\" data-sizes=\"(max-width: 700px) 100vw, 700px\" data-ll-status=\"loaded\" \/><\/p>\n<h3>Combine 3+2-axis with One-Time 3-axis Machining<\/h3>\n<p>However, the advantage of the 3-axis machining solution lies in its ability to duplicate many parts per process. So it can improve machine utilization in the machining. On the other hand, the 3+2 axis machine typically processes one part at a time, reducing machine utilization due to the frequent loading and unloading of workpieces. In addition, we need to use machine tool detection probes to compensate for positioning errors during machining changeovers.<\/p>\n<p>During the machining process, we need to take everything into account. Finally, we chose to combine 3+2 axis machining and a one-time 3-axis process for producing the polyhedral parts, which is the most efficient processing solution.<\/p>\n<h2>Highlights of Fixture Design<\/h2>\n<p>As we mentioned above, the 5-axis machining route typically processes one part at a time. However, through careful analysis and design, we can achieve machining 2 workpieces in one setup. Combined with zero-point quick-change bases, as shown in Figure 3, two parts can be machined simultaneously. We named these A\/B bases, where the A base processes inside the machine while the B base is clamped outside. This improves the problem of under-utilization of machining time on 5-axis machines.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-53350 perfmatters-lazy entered pmloaded\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/fixture-design-of-polyhedral-part-optimized.jpg\" sizes=\"auto, (max-width: 700px) 100vw, 700px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/fixture-design-of-polyhedral-part-optimized.jpg 700w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/fixture-design-of-polyhedral-part-300x204-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/fixture-design-of-polyhedral-part-150x102-optimized.jpg 150w\" alt=\"fixture design of polyhedral part\" width=\"700\" height=\"477\" data-src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/fixture-design-of-polyhedral-part-optimized.jpg\" data-srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/fixture-design-of-polyhedral-part-optimized.jpg 700w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/fixture-design-of-polyhedral-part-300x204-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/fixture-design-of-polyhedral-part-150x102-optimized.jpg 150w\" data-sizes=\"(max-width: 700px) 100vw, 700px\" data-ll-status=\"loaded\" \/><\/p>\n<h2>Conclusion<\/h2>\n<p>This article compared two process routes for machining an aluminum polyhedral part.

Additionally, these machined parts require black anodizing to prevent oxidation and improve wear resistance.\r\n<h2>Key Dimensions Machining Requirements<\/h2>\r\n<ul>\r\n \t<li>Flatness: 0.01;<\/li>\r\n \t<li>Two \u22052.3+0.015mm precision holes, with a positional tolerance of 0.05mm;<\/li>\r\n \t<li>Two \u22053.5+0.015mm precision holes, with a positional tolerance of 0.05mm;<\/li>\r\n \t<li>Two \u22052.5+0.015mm precision holes, with a positional tolerance of 0.05mm;<\/li>\r\n \t<li>Perpendicularity relative to Datum A: 0.02mm<\/li>\r\n \t<li>Linear dimension: 38.88-0.02mm<\/li>\r\n<\/ul>\r\n<img class=\"alignnone size-full wp-image-53348 perfmatters-lazy entered pmloaded\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/key-machining-requirements-of-polyhedral-part-optimized.jpg\" sizes=\"(max-width: 700px) 100vw, 700px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/key-machining-requirements-of-polyhedral-part-optimized.jpg 700w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/key-machining-requirements-of-polyhedral-part-300x195-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/key-machining-requirements-of-polyhedral-part-150x98-optimized.jpg 150w\" alt=\"key machining requirements of polyhedral part\" width=\"700\" height=\"455\" data-src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/key-machining-requirements-of-polyhedral-part-optimized.jpg\" data-srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/key-machining-requirements-of-polyhedral-part-optimized.jpg 700w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/key-machining-requirements-of-polyhedral-part-300x195-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/key-machining-requirements-of-polyhedral-part-150x98-optimized.jpg 150w\" data-sizes=\"(max-width: 700px) 100vw, 700px\" data-ll-status=\"loaded\" \/>\r\n<h2>Machinability Analysis<\/h2>\r\nLet\u2018s check the machinability characteristics of this polyhedral component. The maximum external dimensions of the product are 46.88\u00d716.41\u00d710.91 mm. Its machining tolerance requirements are as follows:\r\n<ul>\r\n \t<li>The strictest dimension tolerance of the part is 38.88-0.02 mm, which can be maintained by two times fine milling at the same path.<\/li>\r\n \t<li>Other tolerances of \u00b10.03 mm and above can be guaranteed with a single fine milling.<\/li>\r\n \t<li>The three sets of +0.015 mm precision holes can be ensured through precision reaming.<\/li>\r\n \t<li>Positional accuracy is best achieved by machining the measured hole and reference datum in the same process.<\/li>\r\n \t<li>Perpendicularity of 0.02mm can be maintained by machining in the same process as Datum A or using Datum A as the reference.<\/li>\r\n \t<li>The flatness of 0.01 requires proper machining parameters. So this finishing machining should employed later in the whole process to minimize deformation.<\/li>\r\n<\/ul>\r\nFinally, the product also requires age hardening to release material stress and ensure long-term dimensional stability. Since the product is not big and the material removal rate is less than 80%, a single precipitation heat treatment before machining is sufficient.\r\n<h2>Process Route Comparison for Machining Aluminum Polyhedral Parts<\/h2>\r\nComparing the two process routes in the following picture shows that the 3-axis machining solutions require five process procedures, each needing a custom fixture. In contrast, using 3+2 axis machining, supplemented by a 3-axis machine to remove residual material at the joint position, requires only two process procedures and fewer fixtures.\r\n\r\nFor small batch orders from 50 to 1000, the second machining solution has a significant cycle time advantage. At the same time, it better guarantees the key dimensions by completing them in the same process procedure.\r\n\r\n<img class=\"alignnone size-full wp-image-53349 perfmatters-lazy entered pmloaded\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/two-machining-routes-comparison-of-polyhedral-parts-optimized.jpg\" sizes=\"(max-width: 700px) 100vw, 700px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/two-machining-routes-comparison-of-polyhedral-parts-optimized.jpg 700w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/two-machining-routes-comparison-of-polyhedral-parts-300x297-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/two-machining-routes-comparison-of-polyhedral-parts-150x150-optimized.jpg 150w\" alt=\"two machining routes comparison of polyhedral parts\" width=\"700\" height=\"694\" data-src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/two-machining-routes-comparison-of-polyhedral-parts-optimized.jpg\" data-srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/two-machining-routes-comparison-of-polyhedral-parts-optimized.jpg 700w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/two-machining-routes-comparison-of-polyhedral-parts-300x297-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/two-machining-routes-comparison-of-polyhedral-parts-150x150-optimized.jpg 150w\" data-sizes=\"(max-width: 700px) 100vw, 700px\" data-ll-status=\"loaded\" \/>\r\n<h3>Combine 3+2-axis with One-Time 3-axis Machining<\/h3>\r\nHowever, the advantage of the 3-axis machining solution lies in its ability to duplicate many parts per process. So it can improve machine utilization in the machining. On the other hand, the 3+2 axis machine typically processes one part at a time, reducing machine utilization due to the frequent loading and unloading of workpieces. In addition, we need to use machine tool detection probes to compensate for positioning errors during machining changeovers.\r\n\r\nDuring the machining process, we need to take everything into account. Finally, we chose to combine 3+2 axis machining and a one-time 3-axis process for producing the polyhedral parts, which is the most efficient processing solution.\r\n<h2>Highlights of Fixture Design<\/h2>\r\nAs we mentioned above, the 5-axis machining route typically processes one part at a time. However, through careful analysis and design, we can achieve machining 2 workpieces in one setup. Combined with zero-point quick-change bases, as shown in Figure 3, two parts can be machined simultaneously. We named these A\/B bases, where the A base processes inside the machine while the B base is clamped outside. This improves the problem of under-utilization of machining time on 5-axis machines.\r\n\r\n<img class=\"alignnone size-full wp-image-53350 perfmatters-lazy entered pmloaded\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/fixture-design-of-polyhedral-part-optimized.jpg\" sizes=\"(max-width: 700px) 100vw, 700px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/fixture-design-of-polyhedral-part-optimized.jpg 700w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/fixture-design-of-polyhedral-part-300x204-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/fixture-design-of-polyhedral-part-150x102-optimized.jpg 150w\" alt=\"fixture design of polyhedral part\" width=\"700\" height=\"477\" data-src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/fixture-design-of-polyhedral-part-optimized.jpg\" data-srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/fixture-design-of-polyhedral-part-optimized.jpg 700w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/fixture-design-of-polyhedral-part-300x204-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/07\/fixture-design-of-polyhedral-part-150x102-optimized.jpg 150w\" data-sizes=\"(max-width: 700px) 100vw, 700px\" data-ll-status=\"loaded\" \/>\r\n<h2>Conclusion<\/h2>\r\nThis article compared two process routes for machining an aluminum polyhedral part.
