Operator errors, such as failing to perform tool settings, can lead to crashes. It will result in broken tools, scrapped workpieces, and reordering and reprocessing materials.<\/p>\n<p>In addition, without the automatic tool setter, manual tool setting when entering Z-value data error can also cause machine collision. In this article, we will share our summarized experiences to help you avoid this issue.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-52935\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/broken-workpiece-optimized.jpg\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/broken-workpiece-optimized.jpg 600w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/broken-workpiece-300x178-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/broken-workpiece-150x89-optimized.jpg 150w\" alt=\"broken workpiece\" width=\"600\" height=\"355\" \/><\/p>\n<h2>Three Main Causes Of Machine Crashes<\/h2>\n<p>Before understanding how to avoid workpiece damage caused by machine collision, it is essential to understand the main reasons behind them.<\/p>\n<h3>Toolpath Issues By Programming Engineers<\/h3>\n<p>The CNC programming software MasterCam uses a method of adopting elements of surfaces and lines for machining. If the auxiliary surfaces are not fully enclosed and have missing areas, there is a risk of machine collision. However, these risks can be identified through computer-simulated machining verification, which can check for overcuts on the workpiece to avoid the risk.<\/p>\n<h3>CNC Operator\u2019s Operational Issues<\/h3>\n<p>There are commonly three setting problems that will cause the crashing.<\/p>\n<ul>\n<li><strong>Calling the Wrong Program for Machining<\/strong>: CNC machine operations are controlled by program instructions. When calling a program for machining, the operator must verify that the program name, tools, and clamping lengths match the program sheet.<\/li>\n<li><strong>Calling the Wrong Coordinate<\/strong>: Sometimes, multiple workpieces are machined simultaneously on a CNC machine, there are multiple coordinates such as G54 and G56. Therefore, Calling the wrong coordinate can also lead to machine collision.<\/li>\n<li><strong>Missing Tool Setting or Incorrect Z-Value Data Entry<\/strong>: After the program starts, the tool movement needs to match the actual position of the tool tip with the Z-value data displayed on the machine screen. If there is a significant discrepancy between them, the machining process should be immediately stopped to recheck the program and tool setting data for errors.<\/li>\n<\/ul>\n<h3>Mechanical Failures or Tool Holder Wear<\/h3>\n<p>While the probability of this happening is low with regular maintenance and care of equipment and tools, it can still lead to tool drops and crashes during machining.<\/p>\n<h2>How To Prevent Machine Collision Using Trial Cutting Methods?<\/h2>\n<p>After understanding the main causes of machine collision, it should implement effective preventive measures. In this section, we will focus on how to adopt trial-cutting methods to avoid machine collision when tool setting is missed or Z-value data entry errors occur.<\/p>\n<h3>Trial Cutting Method for Workpieces with Frames<\/h3>\n<p>When a workpiece has a frame, the boundary line is typically used for trial cutting. As shown in the figure, the yellow line represents the boundary line, and only a short distance needs to be trial cut.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-52936 perfmatters-lazy entered pmloaded\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/trial-cutting-method-optimized.jpg\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/trial-cutting-method-optimized.jpg 600w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/trial-cutting-method-300x179-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/trial-cutting-method-150x89-optimized.jpg 150w\" alt=\"trial cutting method\" width=\"600\" height=\"357\" data-src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/trial-cutting-method-optimized.jpg\" data-srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/trial-cutting-method-optimized.jpg 600w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/trial-cutting-method-300x179-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/trial-cutting-method-150x89-optimized.jpg 150w\" data-sizes=\"(max-width: 600px) 100vw, 600px\" data-ll-status=\"loaded\" \/><\/p>\n<p>In the trial cutting process, the Z-value height should be the same as the border height. With a 200mm straight distance and a feed rate of 3000F\/MIN, the trial machining time is 4 seconds, plus about 2 seconds for lowering and raising the tool, totaling around 6 seconds.<\/p>\n<p>The above is a simple method that uses the same spot for trial cutting with each tool. So it is only to verify if the tool setting is too deep, avoiding overcutting or crashing.<\/p>\n<h3>Trial Cutting in Different Machining Areas<\/h3>\n<p>In most cases, except for face sweeping tools, each machining tool should perform trial machining in different areas. In the trial cutting process, the machining depth can be set to the frame plane -0.02MM. If the tool setting is correct, a slight machining mark will be visible after trial machining; if too deep, a more profound mark will appear; if too high, no mark will be seen.<\/p>\n<p>Since this method relies on visual judgment, the error margin is estimated to be 0.05-0.1MM. Unlike using the same spot for trial cutting with each tool, this method checks if the tool setting is too high.<\/p>\n<p>As the marked number in the above figure, the number of trial cuts can be adjusted based on the number of machining tools. However, each trial cut requires a manual judgment, taking about 2 minutes per trial, making it unsuitable for mass production.<\/p>\n<h3>Face Sweeping Machining for Workpieces with Frames<\/h3>\n<p>For parts with borders that require face machining, the first face sweeping tool does not need trial machining as its starting point is outside the workpiece.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-52937 perfmatters-lazy entered pmloaded\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/cutting-tool-path-optimized.jpg\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/cutting-tool-path-optimized.jpg 600w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/cutting-tool-path-300x182-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/cutting-tool-path-150x91-optimized.jpg 150w\" alt=\"cutting tool path\" width=\"600\" height=\"364\" data-src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/cutting-tool-path-optimized.jpg\" data-srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/cutting-tool-path-optimized.jpg 600w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/cutting-tool-path-300x182-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/cutting-tool-path-150x91-optimized.jpg 150w\" data-sizes=\"(max-width: 600px) 100vw, 600px\" data-ll-status=\"loaded\" \/><\/p>\n<h3>Trial Cutting for Workpieces without Frames<\/h3>\n<p>For workpieces without frames, such as those needing re-machining after 3-axis processing of both front and back sides.

Operator errors, such as failing to perform tool settings, can lead to crashes. It will result in broken tools, scrapped workpieces, and reordering and reprocessing materials.\r\n\r\nIn addition, without the automatic tool setter, manual tool setting when entering Z-value data error can also cause machine collision. In this article, we will share our summarized experiences to help you avoid this issue.\r\n\r\n<img class=\"alignnone size-full wp-image-52935\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/broken-workpiece-optimized.jpg\" sizes=\"(max-width: 600px) 100vw, 600px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/broken-workpiece-optimized.jpg 600w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/broken-workpiece-300x178-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/broken-workpiece-150x89-optimized.jpg 150w\" alt=\"broken workpiece\" width=\"600\" height=\"355\" \/>\r\n<h2>Three Main Causes Of Machine Crashes<\/h2>\r\nBefore understanding how to avoid workpiece damage caused by machine collision, it is essential to understand the main reasons behind them.\r\n<h3>Toolpath Issues By Programming Engineers<\/h3>\r\nThe CNC programming software MasterCam uses a method of adopting elements of surfaces and lines for machining. If the auxiliary surfaces are not fully enclosed and have missing areas, there is a risk of machine collision. However, these risks can be identified through computer-simulated machining verification, which can check for overcuts on the workpiece to avoid the risk.\r\n<h3>CNC Operator\u2019s Operational Issues<\/h3>\r\nThere are commonly three setting problems that will cause the crashing.\r\n<ul>\r\n \t<li><strong>Calling the Wrong Program for Machining<\/strong>: CNC machine operations are controlled by program instructions. When calling a program for machining, the operator must verify that the program name, tools, and clamping lengths match the program sheet.<\/li>\r\n \t<li><strong>Calling the Wrong Coordinate<\/strong>: Sometimes, multiple workpieces are machined simultaneously on a CNC machine, there are multiple coordinates such as G54 and G56. Therefore, Calling the wrong coordinate can also lead to machine collision.<\/li>\r\n \t<li><strong>Missing Tool Setting or Incorrect Z-Value Data Entry<\/strong>: After the program starts, the tool movement needs to match the actual position of the tool tip with the Z-value data displayed on the machine screen. If there is a significant discrepancy between them, the machining process should be immediately stopped to recheck the program and tool setting data for errors.<\/li>\r\n<\/ul>\r\n<h3>Mechanical Failures or Tool Holder Wear<\/h3>\r\nWhile the probability of this happening is low with regular maintenance and care of equipment and tools, it can still lead to tool drops and crashes during machining.\r\n<h2>How To Prevent Machine Collision Using Trial Cutting Methods?<\/h2>\r\nAfter understanding the main causes of machine collision, it should implement effective preventive measures. In this section, we will focus on how to adopt trial-cutting methods to avoid machine collision when tool setting is missed or Z-value data entry errors occur.\r\n<h3>Trial Cutting Method for Workpieces with Frames<\/h3>\r\nWhen a workpiece has a frame, the boundary line is typically used for trial cutting. As shown in the figure, the yellow line represents the boundary line, and only a short distance needs to be trial cut.\r\n\r\n<img class=\"alignnone size-full wp-image-52936 perfmatters-lazy entered pmloaded\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/trial-cutting-method-optimized.jpg\" sizes=\"(max-width: 600px) 100vw, 600px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/trial-cutting-method-optimized.jpg 600w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/trial-cutting-method-300x179-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/trial-cutting-method-150x89-optimized.jpg 150w\" alt=\"trial cutting method\" width=\"600\" height=\"357\" data-src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/trial-cutting-method-optimized.jpg\" data-srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/trial-cutting-method-optimized.jpg 600w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/trial-cutting-method-300x179-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/trial-cutting-method-150x89-optimized.jpg 150w\" data-sizes=\"(max-width: 600px) 100vw, 600px\" data-ll-status=\"loaded\" \/>\r\n\r\nIn the trial cutting process, the Z-value height should be the same as the border height. With a 200mm straight distance and a feed rate of 3000F\/MIN, the trial machining time is 4 seconds, plus about 2 seconds for lowering and raising the tool, totaling around 6 seconds.\r\n\r\nThe above is a simple method that uses the same spot for trial cutting with each tool. So it is only to verify if the tool setting is too deep, avoiding overcutting or crashing.\r\n<h3>Trial Cutting in Different Machining Areas<\/h3>\r\nIn most cases, except for face sweeping tools, each machining tool should perform trial machining in different areas. In the trial cutting process, the machining depth can be set to the frame plane -0.02MM. If the tool setting is correct, a slight machining mark will be visible after trial machining; if too deep, a more profound mark will appear; if too high, no mark will be seen.\r\n\r\nSince this method relies on visual judgment, the error margin is estimated to be 0.05-0.1MM. Unlike using the same spot for trial cutting with each tool, this method checks if the tool setting is too high.\r\n\r\nAs the marked number in the above figure, the number of trial cuts can be adjusted based on the number of machining tools. However, each trial cut requires a manual judgment, taking about 2 minutes per trial, making it unsuitable for mass production.\r\n<h3>Face Sweeping Machining for Workpieces with Frames<\/h3>\r\nFor parts with borders that require face machining, the first face sweeping tool does not need trial machining as its starting point is outside the workpiece.\r\n\r\n<img class=\"alignnone size-full wp-image-52937 perfmatters-lazy entered pmloaded\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/cutting-tool-path-optimized.jpg\" sizes=\"(max-width: 600px) 100vw, 600px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/cutting-tool-path-optimized.jpg 600w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/cutting-tool-path-300x182-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/cutting-tool-path-150x91-optimized.jpg 150w\" alt=\"cutting tool path\" width=\"600\" height=\"364\" data-src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/cutting-tool-path-optimized.jpg\" data-srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/cutting-tool-path-optimized.jpg 600w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/cutting-tool-path-300x182-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2024\/06\/cutting-tool-path-150x91-optimized.jpg 150w\" data-sizes=\"(max-width: 600px) 100vw, 600px\" data-ll-status=\"loaded\" \/>\r\n<h3>Trial Cutting for Workpieces without Frames<\/h3>\r\nFor workpieces without frames, such as those needing re-machining after 3-axis processing of both front and back sides. The trial cutting is done on the positioning reference or fixed block to avoid machine collision.\r\n\r\n<\/div>\r\n<\/div>\";}"],"themepark_seo_title":[""],"themepark_seo_description":[""],"themepark_seo_keyword":[""],"_thumbnail_id":["5874"],"_autoid":["2"],"_blocktemname":["\u535a\u5ba2\u8be6\u60c5\u6a21\u677f"],"views":["3777"],"themepark_post_hide_title":["1"],"themepark_paddingblock":["1"],"_trp_automatically_translated_slug_ar":["\u0643\u064a\u0641\u064a\u0629-\u062a\u062c\u0646\u0628-\u062a\u0635\u0627\u062f\u0645-\u0627\u0644\u0645\u0627\u0643\u064a\u0646\u0629-\u0641\u064a-\u0639\u0645\u0644\u064a\u0629-\u0627\u0644\u062a"]},"medium_url":"https:\/\/www.washxing.com\/wp-content\/uploads\/2025\/06\/DM_20250604113746_001-300x150.jpg","thumbnail_url":"https:\/\/www.washxing.com\/wp-content\/uploads\/2025\/06\/DM_20250604113746_001-150x150.jpg","full_url":"https:\/\/www.washxing.com\/wp-content\/uploads\/2025\/06\/DM_20250604113746_001.jpg","_links":{"self":[{"href":"https:\/\/www.washxing.com\/tr\/wp-json\/wp\/v2\/posts\/5844","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.washxing.com\/tr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.washxing.com\/tr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.washxing.com\/tr\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.washxing.com\/tr\/wp-json\/wp\/v2\/comments?post=5844"}],"version-history":[{"count":1,"href":"https:\/\/www.washxing.com\/tr\/wp-json\/wp\/v2\/posts\/5844\/revisions"}],"predecessor-version":[{"id":5875,"href":"https:\/\/www.washxing.com\/tr\/wp-json\/wp\/v2\/posts\/5844\/revisions\/5875"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.washxing.com\/tr\/wp-json\/wp\/v2\/media\/5874"}],"wp:attachment":[{"href":"https:\/\/www.washxing.com\/tr\/wp-json\/wp\/v2\/media?parent=5844"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.washxing.com\/tr\/wp-json\/wp\/v2\/categories?post=5844"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.washxing.com\/tr\/wp-json\/wp\/v2\/tags?post=5844"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
