Since all six external surfaces of the part require machining, the datum relationship must be clearly defined for each reorientation; this prevents the accumulation of dimensional errors that could otherwise arise from repeated repositioning.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">By employing a positioning strategy that corresponds to the one used for the first side, we machine the second side\u2014completing the external profile, mounting surfaces, and the overall thickness of the part.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Upon completion of this step, the part\u2019s external dimensions meet the design specifications. The remaining work focuses primarily on the precision machining of internal cavities and thin-walled structures.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Develop specialized split-type support tooling to enhance stability during internal cavity machining<\/strong><strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Once the external profile of a part has been machined, the processing of its internal cavity becomes one of the most critical stages in the entire manufacturing process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At this point, the vast majority of the material has been removed, leaving the thin-walled sections with very limited structural rigidity. Relying solely on standard fixtures to secure the part can easily lead to localized vibration or structural deformation during machining. Consequently, it is necessary to design specialized support tooling specifically for the final-stage machining of the internal cavity.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Why use a modular (split-type) fixture design?<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For large, thin-walled components, designing the entire support fixture as a single, integrated unit would not only consume a significant amount of material but also increase both machining costs and the time required for fixture fabrication.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We have adopted a modular design, breaking the internal cavity support fixture down into three separate components. These three parts are configured to align with the component\u2019s external geometry, base structure, and side profiles\u2014ensuring the necessary support surface area while simultaneously simplifying the fabrication, installation, and subsequent adjustment of the fixture.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Designing Support Clearances Based on Actual Part Dimensions<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Since the external dimensions of the parts have already been machined to design specifications, the internal dimensions of the fixture cannot be based solely on the theoretical dimensions of the parts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In our fixture design, we use the actual external geometry of the parts as a reference, incorporating a clearance of approximately 0.06\u20130.10 mm per side. This ensures that the parts can be loaded smoothly while guaranteeing full contact between the side and bottom surfaces of the parts and their corresponding support surfaces.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the fixture clearance is too large, the parts may still shift under the influence of cutting forces; conversely, if the clearance is too small, assembly interference may occur, introducing unwanted stress. Fixture design must account not only for dimensions but also for ease of assembly, the contact area of&nbsp;the supports, and the actual cutting loads.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Local Reinforcement of Weak Areas<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For thin-walled structural components, overall support does not necessarily guarantee sufficient rigidity in every localized area.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In such parts, holes with low structural rigidity are particularly prone to deformation and vibration. If these areas lack effective support during machining, the cutting forces exerted by the tool can trigger localized vibration, which compromises the quality of the machined surface and dimensional stability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To address this, we identify weak areas during the fixture design and machining preparation phases, and incorporate auxiliary supports tailored to the specific structure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the aforementioned machining strategy, specific holes can be temporarily reinforced using suitable filler materials\u2014such as moldable putty or fire-resistant sealing compound\u2014or by employing improvised fillers, like a damp towel that is tightened into place after being soaked. This helps to mitigate localized vibration.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"489\" src=\"https:\/\/xtmade.com\/wp-content\/uploads\/2026\/11\/Hole-in-a-part-with-low-structural-strength-1024x489.webp\" alt=\"Diagram of weak hole locations on the part, with holes 1 and 2\u2014which require auxiliary support\u2014marked.\" class=\"wp-image-11682\" style=\"aspect-ratio:2.108108108108108;width:803px;height:auto\" title=\"\" srcset=\"https:\/\/xtmade.com\/wp-content\/uploads\/2026\/11\/Hole-in-a-part-with-low-structural-strength-1024x489.webp 1024w, https:\/\/xtmade.com\/wp-content\/uploads\/2026\/11\/Hole-in-a-part-with-low-structural-strength-300x143.webp 300w, https:\/\/xtmade.com\/wp-content\/uploads\/2026\/11\/Hole-in-a-part-with-low-structural-strength-768x367.webp 768w, https:\/\/xtmade.com\/wp-content\/uploads\/2026\/11\/Hole-in-a-part-with-low-structural-strength-1536x734.webp 1536w, https:\/\/xtmade.com\/wp-content\/uploads\/2026\/11\/Hole-in-a-part-with-low-structural-strength-2048x978.webp 2048w, https:\/\/xtmade.com\/wp-content\/uploads\/2026\/11\/Hole-in-a-part-with-low-structural-strength-18x9.webp 18w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Such auxiliary supports must be evaluated based on factors including the material, cutting fluid, the tool&#8217;s range of motion, and chip evacuation conditions; they must neither interfere with the normal operation of the tool nor allow any filler material to enter the machining zone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">By combining modular fixturing with localized auxiliary support, it is possible to enhance the overall machining stability of thin-walled components during the final stages, without relying on excessive clamping force.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Optimizing CNC Toolpaths to Reduce Deformation Caused by Cutting Forces<\/strong><strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Even when the workholding setup provides sufficient support, an ill-conceived toolpath can still cause thin-walled structures to vibrate or undergo elastic deformation due to cutting forces.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, once the clamping strategy has been finalized, it is essential to specifically optimize the toolpaths used for machining internal cavities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For such components with low structural rigidity, the primary focus of toolpath planning is not merely to shorten machining time, but to ensure the cutting process remains as smooth as possible, preventing sudden fluctuations in cutting forces.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Prioritize reciprocating toolpaths along the length of the part<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">When machining internal cavities, it is preferable to employ a reciprocating cutting strategy aligned with the length of the part, thereby minimizing unnecessary lateral movement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The primary objective is to maintain a relatively consistent direction for the main cutting forces, preventing frequent shifts in force orientation and reducing the risk of thin-walled structures being subjected to alternating loads.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Naturally, the specific toolpath direction must be determined by considering factors such as the part\u2019s support points, wall thickness distribution, and the tool entry direction; it should not be assumed that a single, uniform machining direction is suitable for all thin-walled components.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"305\" height=\"228\" src=\"https:\/\/xtmade.com\/wp-content\/uploads\/2026\/11\/Toolpath-for-complete-internal-cavity-machining.webp\" alt=\"Toolpath diagram for the entire internal cavity, showing the reciprocating machining path along the length of the part.\" class=\"wp-image-11684\" style=\"aspect-ratio:1.337810979370845;width:760px;height:auto\" title=\"\" srcset=\"https:\/\/xtmade.com\/wp-content\/uploads\/2026\/11\/Toolpath-for-complete-internal-cavity-machining.webp 305w, https:\/\/xtmade.com\/wp-content\/uploads\/2026\/11\/Toolpath-for-complete-internal-cavity-machining-300x224.webp 300w, https:\/\/xtmade.com\/wp-content\/uploads\/2026\/11\/Toolpath-for-complete-internal-cavity-machining-16x12.webp 16w\" sizes=\"(max-width: 305px) 100vw, 305px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Reducing Sharp Turns in Toolpaths and Sudden Fluctuations in Cutting Load<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">When a cutting tool frequently changes direction at corners, instantaneous fluctuations in cutting load can occur.

By optimizing the transitions between adjacent toolpaths, we ensure more continuous tool motion.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Furthermore, based on the wall thickness and support conditions of different areas, we carefully configure parameters such as depth of cut, radial width of cut, and feed rate\u2014ensuring that excessive cutting loads are avoided in regions with insufficient rigidity.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"304\" height=\"237\" src=\"https:\/\/xtmade.com\/wp-content\/uploads\/2026\/11\/Close-up-view-of-the-toolpath-for-internal-cavity-machining.webp\" alt=\"Close-up view of the toolpath for internal cavity machining, illustrating optimized path connections and corner handling.\" class=\"wp-image-11683\" style=\"aspect-ratio:1.2827190611195358;width:768px;height:auto\" title=\"\" srcset=\"https:\/\/xtmade.com\/wp-content\/uploads\/2026\/11\/Close-up-view-of-the-toolpath-for-internal-cavity-machining.webp 304w, https:\/\/xtmade.com\/wp-content\/uploads\/2026\/11\/Close-up-view-of-the-toolpath-for-internal-cavity-machining-300x234.webp 300w, https:\/\/xtmade.com\/wp-content\/uploads\/2026\/11\/Close-up-view-of-the-toolpath-for-internal-cavity-machining-15x12.webp 15w\" sizes=\"(max-width: 304px) 100vw, 304px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Controlling Tool Overhang to Enhance Machining Rigidity<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">When machining deep cavities or internal features, the tool overhang\u2014the length of the tool extending from the holder\u2014directly affects machining stability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A longer tool overhang generally reduces the system&#8217;s flexural rigidity, making it more susceptible to vibrations and tool deflection during the cutting process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, while ensuring the requirements for machining depth and clearance are met, we aim to minimize the tool overhang by selecting an appropriate tool diameter, flute length, and overall tool configuration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For parts with complex internal cavities or those requiring multi-directional machining, the use of 4-axis or 5-axis capabilities allows for the optimization of tool orientation and approach angles. This reduces the need for redundant setups, thereby improving machining efficiency and positioning consistency.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It should be noted that 5-axis machining does not automatically eliminate the deformation of thin-walled components. Ultimately, machining quality is determined by the effective coordination of tool orientation, cutting parameters, workholding\/support, and the inherent rigidity of the part itself.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Machining Results: Controlling Deformation of Thin-Walled Structures to Within 0.03 mm<\/strong><strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">By employing a multi-stage rough machining process combined with aging treatment, adhesive-based positioning, specialized modular fixtures, auxiliary support for structurally weak areas, and optimized toolpaths, we successfully resolved the primary deformation issues encountered during the machining of these 7075 aluminum alloy thin-walled components.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For this part, the design tolerance for critical dimensions is \u00b10.03 mm.
