Poorly designed tool path engagement in the CNC program, leaving traces at the entry and exit points of the tool.<\/p>\n<p><strong>Solution<\/strong>: To address the challenge of avoiding tool marks at entry and exit points, a typical approach involves introducing a slight overlap in tool engagement distance (approximately 0.2mm). This technique serves to circumvent potential inaccuracies in the machine\u2019s lead screw precision.<\/p>\n<p>While this strategy effectively prevents the formation of tool marks, it causes an element of repetitive machining when the material of the product is a soft metal.

The cutting tools used for processing soft metals such as aluminum\/copper are generally alloy material mills with 3 to 4 flutes. They have a hardness ranging from HRC55 to HRC65. These milling cutting tools are performed using the bottom edge of the tool, and the part surface may develop distinctive fish scale patterns, impacting its overall appearance.<\/p>\n<p><strong>Solution<\/strong>: Commonly observed in products with high flatness requirements and flat surfaces featuring recessed structures. A remedy is to switch to cutting tools made from synthetic diamond material, which helps achieve smoother surface finishes.<\/p>\n<h2>Aging and Wear of Equipment Components<\/h2>\n<p><strong>Causes<\/strong>: The tools mark on the product surface is attributed to the aging and wear of the equipment\u2019s spindle, bearings, and lead screw. Additionally, inadequate CNC system backlash parameters contribute to pronounced tool marks, particularly when machining rounded corners.<\/p>\n<p><strong>Solution<\/strong>: These issues stem from equipment-related factors and can be addressed by targeted maintenance and replacement.<\/p>\n<h2>Conclusion<\/h2>\n<p>Achieving an ideal surface in the \u00a0CNC machining metals\u00a0demands useful approaches. There are different methods to avoid tool marks and lines that involve a combination of equipment maintenance, fixture enhancements, process adjustments, and programming refinements. By understanding and rectifying these factors, manufacturers can ensure that precision components not only meet dimensional criteria but also exhibit the desired aesthetic qualities.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div><div class=\"layout_badh\"><\/div><\/section>\n\n\n\n<p><\/p>\n\n\n\n<section class=\"wp-block-themepark-block-themepark-area block_layout thempark-block undefined\" id=\"\" style=\"background-color:#ffffff;padding-bottom:30px;padding-top:30px;\" data-swiper-parallax=\"-700\"><div class=\"block_layout_in\" style=\"\">\n<div class=\"wp-block-column block_layout_in\">\n<div class=\"wp-block-themepark-block-themepark-wright content-super-p\" style=\"font-size:12px;line-height:20px;padding:1px 10px 4px 10px;\">\n<div class=\"wp-block-column\">\n<h2 class=\"wp-block-heading has-text-align-left has-black-color has-text-color has-link-color has-medium-font-size wp-elements-03e3bd26e3714570f9cb9e0c231642cf\">Recommendations <\/h2>\n\n\n\n<p class=\"has-text-align-center has-monte-white-color has-text-color has-link-color has-normal-font-size wp-elements-a419f2b814e1bdd68ac5a703475046d3\"><\/p>\n\n\n\n<div class=\"wp-block-themepark-block-themepark-xian theme_fang_out\" style=\"text-align:left;padding-top:8px;padding-bottom:33px;\"><div class=\"fangbox\" style=\"width:21px;height:4px;background-color:#f29900;\"><div class=\"bkbor\" style=\"width:218px;background-color:#f29900;\"><\/div><\/div><\/div>\n<\/div>\n<\/div>\n\n\n<div class=\"product_loop  radius   mian_loop\" id=\"pro_list_2\"><div class=\"product_post  dbms h_w\" ><div class=\"product_info\"><h3 class=\"pro_title date-title-box\"><a href=\"https:\/\/www.washxing.com\/hu\/causes-and-solutions-for-tool-marks-in-machining-metal\/\"><div class=\"date-title\"><time><span>04<\/span><span>2025.06<\/span> <\/time><span class=\"tittext\">A szersz\u00e1mnyomok okai \u00e9s megold\u00e1sai a f\u00e9m megmunk\u00e1l\u00e1s\u00e1n\u00e1l<\/span>   <\/div><\/a><\/h3><p class=\"des\">A prec\u00edzi\u00f3s f\u00e9malkatr\u00e9szek gy\u00e1rt\u00e1sa gyakran k\u00fcl\u00f6nb\u00f6z\u0151 prec\u00edzi\u00f3s megmunk\u00e1l\u00e1si technol\u00f3gi\u00e1k alkalmaz\u00e1s\u00e1val t\u00f6rt\u00e9nik, a CNC megmunk\u00e1l\u00e1s az egyik legelterjedtebb m\u00f3dszer.

Alternatively, explore alternative fixture options based on specific part structures, tailoring the solution to the particular problem.\r\n\r\n<img class=\"alignnone size-full wp-image-36877 perfmatters-lazy entered pmloaded\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/tool-cutting-surface-optimized.jpg\" sizes=\"(max-width: 800px) 100vw, 800px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/tool-cutting-surface-optimized.jpg 800w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/tool-cutting-surface-300x138-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/tool-cutting-surface-150x69-optimized.jpg 150w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/tool-cutting-surface-768x353-optimized.jpg 768w\" alt=\"tool cutting surface\" width=\"800\" height=\"368\" data-src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/tool-cutting-surface-optimized.jpg\" data-srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/tool-cutting-surface-optimized.jpg 800w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/tool-cutting-surface-300x138-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/tool-cutting-surface-150x69-optimized.jpg 150w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/tool-cutting-surface-768x353-optimized.jpg 768w\" data-sizes=\"(max-width: 800px) 100vw, 800px\" data-ll-status=\"loaded\" \/>\r\n<h2>Process-related Factors<\/h2>\r\n<strong>Causes<\/strong>: Certain product manufacturing processes may contribute to the issue. For instance, products like tablet PC rear shells undergo a sequence of machining steps involving punching side holes followed by CNC milling of the edges. This sequence can lead to noticeable tool marks when milling reaches the side-hole positions.\r\n\r\n<strong>Solution<\/strong>: A common instance of this problem occurs when the aluminum alloy is chosen for electronic product shells. To resolve it, the process can be modified by replacing the side hole punching plus milling with only CNC milling. At the same time, ensuring consistent tool engagement and reducing uneven cutting when milling.\r\n\r\n<img class=\"alignnone size-full wp-image-36879 perfmatters-lazy entered pmloaded\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/cutting-tool-path-optimized.jpg\" sizes=\"(max-width: 800px) 100vw, 800px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/cutting-tool-path-optimized.jpg 800w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/cutting-tool-path-300x157-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/cutting-tool-path-150x79-optimized.jpg 150w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/cutting-tool-path-768x402-optimized.jpg 768w\" alt=\"cutting tool path\" width=\"800\" height=\"419\" data-src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/cutting-tool-path-optimized.jpg\" data-srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/cutting-tool-path-optimized.jpg 800w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/cutting-tool-path-300x157-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/cutting-tool-path-150x79-optimized.jpg 150w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/cutting-tool-path-768x402-optimized.jpg 768w\" data-sizes=\"(max-width: 800px) 100vw, 800px\" data-ll-status=\"loaded\" \/>\r\n<h2>Inadequate Programming of Tool Path Engagement<\/h2>\r\n<strong>Causes<\/strong>: This issue commonly arises during the 2D contour machining phase of product production. Poorly designed tool path engagement in the CNC program, leaving traces at the entry and exit points of the tool.\r\n\r\n<strong>Solution<\/strong>: To address the challenge of avoiding tool marks at entry and exit points, a typical approach involves introducing a slight overlap in tool engagement distance (approximately 0.2mm). This technique serves to circumvent potential inaccuracies in the machine\u2019s lead screw precision.\r\n\r\nWhile this strategy effectively prevents the formation of tool marks, it causes an element of repetitive machining when the material of the product is a soft metal. Consequently, this section may exhibit variations in texture and color compared to other areas.\r\n\r\n<img class=\"alignnone size-full wp-image-36880 perfmatters-lazy entered pmloaded\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/optimized-toolpath-optimized.jpg\" sizes=\"(max-width: 800px) 100vw, 800px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/optimized-toolpath-optimized.jpg 800w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/optimized-toolpath-300x149-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/optimized-toolpath-150x74-optimized.jpg 150w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/optimized-toolpath-768x380-optimized.jpg 768w\" alt=\"optimized toolpath\" width=\"800\" height=\"396\" data-src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/optimized-toolpath-optimized.jpg\" data-srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/optimized-toolpath-optimized.jpg 800w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/optimized-toolpath-300x149-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/optimized-toolpath-150x74-optimized.jpg 150w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/08\/optimized-toolpath-768x380-optimized.jpg 768w\" data-sizes=\"(max-width: 800px) 100vw, 800px\" data-ll-status=\"loaded\" \/>\r\n<h2>Fish Scale Patterns on Flat Machined Surfaces<\/h2>\r\n<strong>Causes<\/strong>: Fish scale or circular patterns appearing on the product\u2019s flat surfaces. The cutting tools used for processing soft metals such as aluminum\/copper are generally alloy material mills with 3 to 4 flutes. They have a hardness ranging from HRC55 to HRC65. These milling cutting tools are performed using the bottom edge of the tool, and the part surface may develop distinctive fish scale patterns, impacting its overall appearance.\r\n\r\n<strong>Solution<\/strong>: Commonly observed in products with high flatness requirements and flat surfaces featuring recessed structures. A remedy is to switch to cutting tools made from synthetic diamond material, which helps achieve smoother surface finishes.\r\n<h2>Aging and Wear of Equipment Components<\/h2>\r\n<strong>Causes<\/strong>: The tools mark on the product surface is attributed to the aging and wear of the equipment\u2019s spindle, bearings, and lead screw. Additionally, inadequate CNC system backlash parameters contribute to pronounced tool marks, particularly when machining rounded corners.\r\n\r\n<strong>Solution<\/strong>: These issues stem from equipment-related factors and can be addressed by targeted maintenance and replacement.\r\n<h2>Conclusion<\/h2>\r\nAchieving an ideal surface in the \u00a0CNC machining metals\u00a0demands useful approaches. There are different methods to avoid tool marks and lines that involve a combination of equipment maintenance, fixture enhancements, process adjustments, and programming refinements. By understanding and rectifying these factors, manufacturers can ensure that precision components not only meet dimensional criteria but also exhibit the desired aesthetic qualities.\";}"],"themepark_seo_title":[""],"themepark_seo_description":[""],"themepark_seo_keyword":[""],"_thumbnail_id":["5877"],"_autoid":["2"],"_blocktemname":["\u535a\u5ba2\u8be6\u60c5\u6a21\u677f"],"views":["3880"],"themepark_post_hide_title":["1"],"themepark_paddingblock":["1"],"_trp_automatically_translated_slug_pt_PT":["causas-e-solucoes-para-as-marcas-de-ferramentas-na-maquinagem-de-metais"]},"medium_url":"https:\/\/www.washxing.com\/wp-content\/uploads\/2025\/06\/DM_20250604114300_001-300x150.jpg","thumbnail_url":"https:\/\/www.washxing.com\/wp-content\/uploads\/2025\/06\/DM_20250604114300_001-150x150.jpg","full_url":"https:\/\/www.washxing.com\/wp-content\/uploads\/2025\/06\/DM_20250604114300_001.jpg","_links":{"self":[{"href":"https:\/\/www.washxing.com\/hu\/wp-json\/wp\/v2\/posts\/5843","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.washxing.com\/hu\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.washxing.com\/hu\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.washxing.com\/hu\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.washxing.com\/hu\/wp-json\/wp\/v2\/comments?post=5843"}],"version-history":[{"count":1,"href":"https:\/\/www.washxing.com\/hu\/wp-json\/wp\/v2\/posts\/5843\/revisions"}],"predecessor-version":[{"id":5878,"href":"https:\/\/www.washxing.com\/hu\/wp-json\/wp\/v2\/posts\/5843\/revisions\/5878"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.washxing.com\/hu\/wp-json\/wp\/v2\/media\/5877"}],"wp:attachment":[{"href":"https:\/\/www.washxing.com\/hu\/wp-json\/wp\/v2\/media?parent=5843"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.washxing.com\/hu\/wp-json\/wp\/v2\/categories?post=5843"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.washxing.com\/hu\/wp-json\/wp\/v2\/tags?post=5843"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
