Same as the last step, we need to measure the machine position on the other side of the datum using the centering bar. Then, check the current relative Y value of the machine. For example, if we assume the Y value is \u201c92mm\u201d, the centering diameter is 10mm centering diameter, and the fixture datum to the rotary table is 41mm.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-31133 perfmatters-lazy entered pmloaded\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-optimized.jpg\" sizes=\"auto, (max-width: 801px) 100vw, 801px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-optimized.jpg 801w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-300x150-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-150x75-optimized.jpg 150w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-768x384-optimized.jpg 768w\" alt=\"determine the Y value\" width=\"801\" height=\"400\" data-src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-optimized.jpg\" data-srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-optimized.jpg 801w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-300x150-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-150x75-optimized.jpg 150w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-768x384-optimized.jpg 768w\" data-sizes=\"(max-width: 801px) 100vw, 801px\" data-ll-status=\"loaded\" \/><\/p>\n<p>&nbsp;<\/p>\n<h3>Step 4: Determine the Position of the Rotation Center in the Y-axis<\/h3>\n<p>Referring to the values in the previous step, we can calculate that 92\/2 = 46mm, so half of the Y value of 46mm. Then, we move the centering bar 46mm negatively towards the Y-axis.<\/p>\n<p>As shown by the picture, the centering bar is now just aligned with the rotational axis of the rotary table. At the time, the position of the alignment point is the zero point of the Y value of the machine. In this way, we have completed half of the operation work.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-31134 perfmatters-lazy entered pmloaded\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-optimized.jpg\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-optimized.jpg 800w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-300x134-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-150x67-optimized.jpg 150w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-768x343-optimized.jpg 768w\" alt=\"find the Z position\" width=\"800\" height=\"357\" data-src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-optimized.jpg\" data-srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-optimized.jpg 800w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-300x134-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-150x67-optimized.jpg 150w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-768x343-optimized.jpg 768w\" data-sizes=\"(max-width: 800px) 100vw, 800px\" data-ll-status=\"loaded\" \/><\/p>\n<p>&nbsp;<\/p>\n<h3>Step 5: Find the Position of the Rotation Center in the Z-axis<\/h3>\n<p>Finding the Z value is relatively simple. After the rotary table returns to the A0 position, the zero point of the Z-axis of the rotary axis can be determined by moving down 41mm with the datum surface as the calculation base. This value is calculated using the formula \u201c(92-10)\/2\u201d, where 92 is the Y-value found earlier and 10 is the diameter of the centering bar. By applying this formula, the Z value is determined.<\/p>\n<p>Finally, the intersection of the Z and Y axis is the rotation center around the X axis. With these steps, we can determine the rotation center of the 4-axis rotary table.<\/p>\n<\/div>\n<\/div>\n<div class=\"elementor-element elementor-element-aec32e2 elementor-widget elementor-widget-heading\" data-id=\"aec32e2\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n<div class=\"elementor-widget-container\">\n<h2 class=\"elementor-heading-title elementor-size-default\">Coordinate Setting in Programming<\/h2>\n<\/div>\n<\/div>\n<div class=\"elementor-element elementor-element-a9c6396 elementor-widget elementor-widget-text-editor\" data-id=\"a9c6396\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n<div class=\"elementor-widget-container\">\n<p>After determining the center value, in the programming software, we need to synchronize the program coordinates with the rotation axis of the 4-axis rotary table (relative distance of the coordinates to the fixture datum). Then we can output the program for all machined surfaces. So, the machining of multiple faces of a part can be completed by one coordinate.<\/p>\n<\/div>\n<\/div>\n<div class=\"elementor-element elementor-element-dbb0656 elementor-widget elementor-widget-heading\" data-id=\"dbb0656\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n<div class=\"elementor-widget-container\">\n<h2 class=\"elementor-heading-title elementor-size-default\">Conclus\u00e3o<\/h2>\n<\/div>\n<\/div>\n<div class=\"elementor-element elementor-element-d95a44b elementor-widget elementor-widget-text-editor\" data-id=\"d95a44b\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n<div class=\"elementor-widget-container\">\n<p>By determining the rotation center of the 4-axis rotary table, we can complete the machining of multiple surfaces or four-axis simultaneous machining in a single clamping process with one coordinate. It also avoids the trouble of setting the machining coordinates for each machined surface during multi-face machining. In this way, we can ensure relative accuracy between the machined surfaces.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\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\">Recomenda\u00e7\u00f5es <\/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\/pt\/what-is-sfm-a-complete-guide-to-surface-feet-per-minute-in-machining-2\/\"><div class=\"date-title\"><time><span>16<\/span><span>2025.05<\/span> <\/time><span class=\"tittext\">Press Fit Tolerance: Defination, Practices, And Calculation<\/span>   <\/div><\/a><\/h3><p class=\"des\">The manufacturing industry is highly precision-centric, where even the slightest of margins can create huge differences in product quality, cost, and utility.

In order to complete the machining of multiple faces in one coordinate, the programming coordinates must be synchronized with the coordinates of the rotary table. In this article, we will share a method to determine the rotation center of a 4-axis rotary table.\r\n\r\n<\/div>\r\n<\/div>\r\n<div class=\"elementor-element elementor-element-34612e0 elementor-widget elementor-widget-heading\" data-id=\"34612e0\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\r\n<div class=\"elementor-widget-container\">\r\n<h2 class=\"elementor-heading-title elementor-size-default\">Steps to Determine Center Rotation of a 4-Axis Rotary Table<\/h2>\r\n<\/div>\r\n<\/div>\r\n<div class=\"elementor-element elementor-element-9bdefb3 elementor-widget elementor-widget-text-editor\" data-id=\"9bdefb3\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\r\n<div class=\"elementor-widget-container\">\r\n\r\nHere, we show a 4-axis rotary table that rotates around the X-axis of a machine tool, where the axis of rotation is called the A-axis. In a word, all we need to do is to determine the Y\/Z coordinates of the center of rotation on the 4-axis machine.\r\n\r\nIn addition, the X coordinate values are determined by the placement of the product, so we won\u2019t go into detail here. The following are the specific steps to determine the center of rotation.\r\n\r\n<img class=\"size-full wp-image-31130 aligncenter\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/datum-plane-optimized.jpg\" sizes=\"(max-width: 800px) 100vw, 800px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/datum-plane-optimized.jpg 800w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/datum-plane-300x127-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/datum-plane-150x63-optimized.jpg 150w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/datum-plane-768x324-optimized.jpg 768w\" alt=\"datum plane\" width=\"800\" height=\"338\" \/>\r\n\r\n&nbsp;\r\n<h3>Step 1: Calibrate the Fixture Reference Plane<\/h3>\r\nFirstly, use the calibration table to calibrate the fixture datum plane (the yellow surface).

Then, use a centering bar to measure the machine position where the datum plane is located. In the relative coordinate setting, set the Y coordinate to \u201c0\u201d.\r\n\r\n<img class=\"alignnone size-full wp-image-31132 perfmatters-lazy entered pmloaded\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/measuring-the-machine-position-after-rotation-optimized.jpg\" sizes=\"(max-width: 800px) 100vw, 800px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/measuring-the-machine-position-after-rotation-optimized.jpg 800w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/measuring-the-machine-position-after-rotation-300x160-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/measuring-the-machine-position-after-rotation-150x80-optimized.jpg 150w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/measuring-the-machine-position-after-rotation-768x409-optimized.jpg 768w\" alt=\"measuring the machine position after rotation\" width=\"800\" height=\"426\" data-src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/measuring-the-machine-position-after-rotation-optimized.jpg\" data-srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/measuring-the-machine-position-after-rotation-optimized.jpg 800w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/measuring-the-machine-position-after-rotation-300x160-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/measuring-the-machine-position-after-rotation-150x80-optimized.jpg 150w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/measuring-the-machine-position-after-rotation-768x409-optimized.jpg 768w\" data-sizes=\"(max-width: 800px) 100vw, 800px\" data-ll-status=\"loaded\" \/>\r\n\r\n&nbsp;\r\n<h3>Step 3: Measure the Value of the Datum Plane<\/h3>\r\nNext, rotate the A-axis 180 degrees in the negative direction. Same as the last step, we need to measure the machine position on the other side of the datum using the centering bar. Then, check the current relative Y value of the machine. For example, if we assume the Y value is \u201c92mm\u201d, the centering diameter is 10mm centering diameter, and the fixture datum to the rotary table is 41mm.\r\n\r\n<img class=\"alignnone size-full wp-image-31133 perfmatters-lazy entered pmloaded\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-optimized.jpg\" sizes=\"(max-width: 801px) 100vw, 801px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-optimized.jpg 801w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-300x150-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-150x75-optimized.jpg 150w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-768x384-optimized.jpg 768w\" alt=\"determine the Y value\" width=\"801\" height=\"400\" data-src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-optimized.jpg\" data-srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-optimized.jpg 801w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-300x150-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-150x75-optimized.jpg 150w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/determine-the-Y-value-768x384-optimized.jpg 768w\" data-sizes=\"(max-width: 801px) 100vw, 801px\" data-ll-status=\"loaded\" \/>\r\n\r\n&nbsp;\r\n<h3>Step 4: Determine the Position of the Rotation Center in the Y-axis<\/h3>\r\nReferring to the values in the previous step, we can calculate that 92\/2 = 46mm, so half of the Y value of 46mm. Then, we move the centering bar 46mm negatively towards the Y-axis.\r\n\r\nAs shown by the picture, the centering bar is now just aligned with the rotational axis of the rotary table. At the time, the position of the alignment point is the zero point of the Y value of the machine. In this way, we have completed half of the operation work.\r\n\r\n<img class=\"alignnone size-full wp-image-31134 perfmatters-lazy entered pmloaded\" src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-optimized.jpg\" sizes=\"(max-width: 800px) 100vw, 800px\" srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-optimized.jpg 800w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-300x134-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-150x67-optimized.jpg 150w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-768x343-optimized.jpg 768w\" alt=\"find the Z position\" width=\"800\" height=\"357\" data-src=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-optimized.jpg\" data-srcset=\"https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-optimized.jpg 800w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-300x134-optimized.jpg 300w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-150x67-optimized.jpg 150w, https:\/\/waykenrm.com\/wp-content\/uploads\/2023\/07\/find-the-Z-position-768x343-optimized.jpg 768w\" data-sizes=\"(max-width: 800px) 100vw, 800px\" data-ll-status=\"loaded\" \/>\r\n\r\n&nbsp;\r\n<h3>Step 5: Find the Position of the Rotation Center in the Z-axis<\/h3>\r\nFinding the Z value is relatively simple. After the rotary table returns to the A0 position, the zero point of the Z-axis of the rotary axis can be determined by moving down 41mm with the datum surface as the calculation base. This value is calculated using the formula \u201c(92-10)\/2\u201d, where 92 is the Y-value found earlier and 10 is the diameter of the centering bar. By applying this formula, the Z value is determined.\r\n\r\nFinally, the intersection of the Z and Y axis is the rotation center around the X axis. With these steps, we can determine the rotation center of the 4-axis rotary table.\r\n\r\n<\/div>\r\n<\/div>\r\n<div class=\"elementor-element elementor-element-aec32e2 elementor-widget elementor-widget-heading\" data-id=\"aec32e2\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\r\n<div class=\"elementor-widget-container\">\r\n<h2 class=\"elementor-heading-title elementor-size-default\">Coordinate Setting in Programming<\/h2>\r\n<\/div>\r\n<\/div>\r\n<div class=\"elementor-element elementor-element-a9c6396 elementor-widget elementor-widget-text-editor\" data-id=\"a9c6396\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\r\n<div class=\"elementor-widget-container\">\r\n\r\nAfter determining the center value, in the programming software, we need to synchronize the program coordinates with the rotation axis of the 4-axis rotary table (relative distance of the coordinates to the fixture datum). Then we can output the program for all machined surfaces. So, the machining of multiple faces of a part can be completed by one coordinate.\r\n\r\n<\/div>\r\n<\/div>\r\n<div class=\"elementor-element elementor-element-dbb0656 elementor-widget elementor-widget-heading\" data-id=\"dbb0656\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\r\n<div class=\"elementor-widget-container\">\r\n<h2 class=\"elementor-heading-title elementor-size-default\">Conclusion<\/h2>\r\n<\/div>\r\n<\/div>\r\n<div class=\"elementor-element elementor-element-d95a44b elementor-widget elementor-widget-text-editor\" data-id=\"d95a44b\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\r\n<div class=\"elementor-widget-container\">\r\n\r\nBy determining the rotation center of the 4-axis rotary table, we can complete the machining of multiple surfaces or four-axis simultaneous machining in a single clamping process with one coordinate. It also avoids the trouble of setting the machining coordinates for each machined surface during multi-face machining. In this way, we can ensure relative accuracy between the machined surfaces.\r\n\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\";}"],"themepark_seo_title":[""],"themepark_seo_description":[""],"themepark_seo_keyword":[""],"_thumbnail_id":["5879"],"_autoid":["2"],"_blocktemname":["\u535a\u5ba2\u8be6\u60c5\u6a21\u677f"],"views":["4225"],"themepark_post_hide_title":["1"],"themepark_paddingblock":["1"]},"medium_url":"https:\/\/www.washxing.com\/wp-content\/uploads\/2025\/06\/DM_20250604114642_001-300x150.jpg","thumbnail_url":"https:\/\/www.washxing.com\/wp-content\/uploads\/2025\/06\/DM_20250604114642_001-150x150.jpg","full_url":"https:\/\/www.washxing.com\/wp-content\/uploads\/2025\/06\/DM_20250604114642_001.jpg","_links":{"self":[{"href":"https:\/\/www.washxing.com\/pt\/wp-json\/wp\/v2\/posts\/5842","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.washxing.com\/pt\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.washxing.com\/pt\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.washxing.com\/pt\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.washxing.com\/pt\/wp-json\/wp\/v2\/comments?post=5842"}],"version-history":[{"count":1,"href":"https:\/\/www.washxing.com\/pt\/wp-json\/wp\/v2\/posts\/5842\/revisions"}],"predecessor-version":[{"id":5880,"href":"https:\/\/www.washxing.com\/pt\/wp-json\/wp\/v2\/posts\/5842\/revisions\/5880"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.washxing.com\/pt\/wp-json\/wp\/v2\/media\/5879"}],"wp:attachment":[{"href":"https:\/\/www.washxing.com\/pt\/wp-json\/wp\/v2\/media?parent=5842"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.washxing.com\/pt\/wp-json\/wp\/v2\/categories?post=5842"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.washxing.com\/pt\/wp-json\/wp\/v2\/tags?post=5842"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
