Such a uniform strategy results in inefficient utilization of the robot&#8217;s capabilities, particularly when dealing with complex geometries where the kinematic performance can vary significantly across different surface regions. In this study, we present an advanced approach based on surface segmentation of the workpiece into regions, where each region is assigned a locally optimal machining direction and speed, derived from the robot&#8217;s kinematic capabilities and the geometry of the surface. An improved machining time index was developed, incorporating a penalty for toolpath transitions, along with a new procedure for determining the optimal number of initial segments. This enables a more realistic estimation of the overall process efficiency. Numerical and experimental results confirm that the proposed region-based strategy achieves up to 22% reduction in machining time compared to conventional unidirectional strategies.<\/p>\n<p><\/p>\n<p style=\"text-align: justify;\"><strong>Keywords:<br \/><\/strong>robot surface machining, machining time optimization, collaborative robots, surface segmentation, machine hammer peening<\/p>\n<p><\/p>\n<p><strong>Copyright (c) 2025 Toma\u017e Pu\u0161nik, Ale\u0161 Hace<br \/><\/strong><br \/><a href=\"https:\/\/creativecommons.org\/licenses\/by\/4.0\/\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-16131\" src=\"https:\/\/revija-ventil.si\/wp-content\/uploads\/\/cc-300x105.png\" alt=\"\" width=\"120\" height=\"42\" srcset=\"https:\/\/revija-ventil.si\/wp-content\/uploads\/cc-300x105.png 300w, https:\/\/revija-ventil.si\/wp-content\/uploads\/cc-400x141.png 400w, https:\/\/revija-ventil.si\/wp-content\/uploads\/cc.png 403w\" sizes=\"(max-width: 120px) 100vw, 120px\" \/><\/a><\/p>\n<p><\/p>\n<p>This work is licensed under a<br \/><a href=\"https:\/\/creativecommons.org\/licenses\/by\/4.0\/\" target=\"_blank\" rel=\"noopener\">Creative Commons Attribution 4.0 International License<\/a>.<\/p>\n<p><\/p>\n<p>Except where otherwise noted, articles in<br \/>this journal are published under the<br \/><a href=\"https:\/\/creativecommons.org\/licenses\/by\/4.0\/\" target=\"_blank\" rel=\"noopener\">Creative Commons Attribution 4.0 International License<\/a><a href=\"https:\/\/creativecommons.org\/licenses\/by\/4.0\/\" target=\"_blank\" rel=\"noopener\">.<\/a><\/p>\n<p>[\/et_pb_text][et_pb_button button_url=&#8221;https:\/\/revija-ventil.si\/wp-content\/uploads\/pusnik_07-2025.pdf&#8221; url_new_window=&#8221;on&#8221; button_text=&#8221;Download PDF&#8221; admin_label=&#8221;Gumb Prenesi PDF&#8221; _builder_version=&#8221;4.27.4&#8243; custom_button=&#8221;on&#8221; button_text_size=&#8221;15px&#8221; button_text_color=&#8221;#00868a&#8221; button_bg_color=&#8221;rgba(0,0,0,0)&#8221; button_border_color=&#8221;#00868a&#8221; button_icon=&#8221;&#xe0e8;||divi||400&#8243; custom_margin=&#8221;||0px||false|false&#8221; custom_margin_tablet=&#8221;||20px||false|false&#8221; custom_margin_phone=&#8221;&#8221; custom_margin_last_edited=&#8221;on|desktop&#8221; custom_padding=&#8221;||||false|false&#8221; locked=&#8221;off&#8221; global_colors_info=&#8221;{}&#8221; button_border_color__hover_enabled=&#8221;on|hover&#8221; button_border_color__hover=&#8221;#00868a&#8221;][\/et_pb_button][et_pb_post_nav in_same_term=&#8221;on&#8221; prev_text=&#8221;Older entries&#8221; next_text=&#8221;Newer entries&#8221; admin_label=&#8221;Navigacija po objavah&#8221; _builder_version=&#8221;4.3.3&#8243; custom_margin=&#8221;||||false|false&#8221; custom_margin_phone=&#8221;||||false|false&#8221; custom_margin_last_edited=&#8221;off|desktop&#8221; custom_padding=&#8221;20px||||false|false&#8221; custom_padding_tablet=&#8221;0px||0px||false|false&#8221; custom_padding_phone=&#8221;0px||0px||false|false&#8221; custom_padding_last_edited=&#8221;on|tablet&#8221; title_text_color_last_edited=&#8221;off|desktop&#8221; global_module=&#8221;11763&#8243; locked=&#8221;off&#8221; global_colors_info=&#8221;{}&#8221; title_text_color__hover_enabled=&#8221;on|desktop&#8221; title_text_color__hover=&#8221;#212b31&#8243;][\/et_pb_post_nav][\/et_pb_column][et_pb_column type=&#8221;1_4&#8243; _builder_version=&#8221;4.16&#8243; custom_padding=&#8221;|||&#8221; global_colors_info=&#8221;{}&#8221; custom_padding__hover=&#8221;|||&#8221;]<\/p>\n<p>[et_pb_sidebar orientation=&#8221;right&#8221; area=&#8221;et_pb_widget_area_4&#8243; disabled_on=&#8221;on|on|off&#8221; _builder_version=&#8221;4.27.4&#8243; global_module=&#8221;11764&#8243; global_colors_info=&#8221;{}&#8221;][\/et_pb_sidebar]<\/p>\n<p>[\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Traditional approaches to robotic surface machining often rely on a predefined, constant direction and speed of tool motion, regardless of the local characteristics of the workpiece.

Ventil","og_description":"Traditional approaches to robotic surface machining often rely on a predefined, constant direction and speed of tool motion, regardless of the local characteristics of the workpiece. Such a uniform strategy results in inefficient utilization of the robot's capabilities, particularly when dealing with complex geometries where the kinematic performance can vary significantly across different surface regions.","og_url":"https:\/\/revija-ventil.si\/en\/improved-time-optimal-planning-of-robotic-surface-finishing-using-a-region-based-approach\/","og_site_name":"Ventil","article_published_time":"2025-07-08T21:31:40+00:00","article_modified_time":"2025-08-13T13:54:33+00:00","og_image":[{"width":1200,"height":1061,"url":"https:\/\/revija-ventil.si\/wp-content\/uploads\/pusnik_07-2025-min.png","type":"image\/png"}],"author":"Denis \u0160enkinc","twitter_card":"summary_large_image","twitter_misc":{"Written by":"Denis \u0160enkinc","Est. reading time":"5 minutes"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"Article","@id":"https:\/\/revija-ventil.si\/en\/improved-time-optimal-planning-of-robotic-surface-finishing-using-a-region-based-approach\/#article","isPartOf":{"@id":"https:\/\/revija-ventil.si\/en\/improved-time-optimal-planning-of-robotic-surface-finishing-using-a-region-based-approach\/"},"author":{"name":"Denis \u0160enkinc","@id":"https:\/\/revija-ventil.si\/en\/#\/schema\/person\/440c2ee7bc0d8f5684aaefb25c60807e"},"headline":"Improved Time-Optimal Planning of Robotic Surface Finishing Using a Region-Based Approach","datePublished":"2025-07-08T21:31:40+00:00","dateModified":"2025-08-13T13:54:33+00:00","mainEntityOfPage":{"@id":"https:\/\/revija-ventil.si\/en\/improved-time-optimal-planning-of-robotic-surface-finishing-using-a-region-based-approach\/"},"wordCount":921,"publisher":{"@id":"https:\/\/revija-ventil.si\/en\/#organization"},"image":{"@id":"https:\/\/revija-ventil.si\/en\/improved-time-optimal-planning-of-robotic-surface-finishing-using-a-region-based-approach\/#primaryimage"},"thumbnailUrl":"https:\/\/revija-ventil.si\/wp-content\/uploads\/pusnik_07-2025-min.png","articleSection":["Exposed articles","Science and expert articles"],"inLanguage":"en-US"},{"@type":"WebPage","@id":"https:\/\/revija-ventil.si\/en\/improved-time-optimal-planning-of-robotic-surface-finishing-using-a-region-based-approach\/","url":"https:\/\/revija-ventil.si\/en\/improved-time-optimal-planning-of-robotic-surface-finishing-using-a-region-based-approach\/","name":"Improved Time-Optimal Planning of Robotic Surface Finishing Using a Region-Based Approach -
