One can either use geometrical or analytical method for cam profile determination. Since the accuracy of the cam profile is very important, mathematical methods are preferred.<\/p>\n<p>Geometrical method for the cam profile determination for an in line roller follower radial cam was shown. In the following figure the cam profile determination for a radial cam with\u00a0 a flat faced follower is shown. In either case the procedure in generating the cam profile involves kinematic inversion; e.g. cam is fixed and the fixed link is rotated around the cam while the follower is displaced relative to the fixed link by an amount given by the motion curve. Before laying out the cam profile, the base circle radius and the motion curve for the whole cycle must be known. The relative positions of the links are same as that of the original motion. Through this process the cam profile is obtained as the envelope of all the cam profile positions.<\/p>\n<p>Geometrical construction even when we use a CAD package will still require a lot of repetitive work. In some CAM packages there are special units within the package with which you can generate a cam profile.<\/p>\n<p style=\"text-align: center\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-2346\" src=\"https:\/\/blog.metu.edu.tr\/eresmech\/files\/2022\/03\/8-4b_clip_image002.gif\" alt=\"\" width=\"888\" height=\"798\" \/><\/p>\n<p align=\"center\"><div class=\"su-image-carousel  su-image-carousel-has-spacing su-image-carousel-has-lightbox su-image-carousel-has-outline su-image-carousel-adaptive su-image-carousel-slides-style-default su-image-carousel-controls-style-dark su-image-carousel-align-center\" style=\"max-width:550px\" data-flickity-options='{\"groupCells\":true,\"cellSelector\":\".su-image-carousel-item\",\"adaptiveHeight\":true,\"cellAlign\":\"left\",\"prevNextButtons\":true,\"pageDots\":false,\"autoPlay\":false,\"imagesLoaded\":true,\"contain\":false,\"selectedAttraction\":1,\"friction\":1}' id=\"su_image_carousel_69d7188004239\"><div class=\"su-image-carousel-item\"><div class=\"su-image-carousel-item-content\"><a href=\"https:\/\/blog.metu.edu.tr\/eresmech\/files\/2022\/09\/kammotion2e_1.gif\" target=\"_blank\" rel=\"noopener noreferrer\" data-caption=\"\"><img loading=\"lazy\" decoding=\"async\" width=\"550\" height=\"400\" src=\"https:\/\/blog.metu.edu.tr\/eresmech\/files\/2022\/09\/kammotion2e_1.gif\" class=\"\" alt=\"\" \/><\/a><\/div><\/div><div class=\"su-image-carousel-item\"><div class=\"su-image-carousel-item-content\"><a href=\"https:\/\/blog.metu.edu.tr\/eresmech\/files\/2022\/09\/kammotion2e_2.gif\" target=\"_blank\" rel=\"noopener noreferrer\" data-caption=\"\"><img loading=\"lazy\" decoding=\"async\" width=\"550\" height=\"400\" src=\"https:\/\/blog.metu.edu.tr\/eresmech\/files\/2022\/09\/kammotion2e_2.gif\" class=\"\" alt=\"\" \/><\/a><\/div><\/div><div class=\"su-image-carousel-item\"><div class=\"su-image-carousel-item-content\"><a href=\"https:\/\/blog.metu.edu.tr\/eresmech\/files\/2022\/09\/kammotion2e_3.gif\" target=\"_blank\" rel=\"noopener noreferrer\" data-caption=\"\"><img loading=\"lazy\" decoding=\"async\" width=\"550\" height=\"400\" src=\"https:\/\/blog.metu.edu.tr\/eresmech\/files\/2022\/09\/kammotion2e_3.gif\" class=\"\" alt=\"\" \/><\/a><\/div><\/div><div class=\"su-image-carousel-item\"><div class=\"su-image-carousel-item-content\"><a href=\"https:\/\/blog.metu.edu.tr\/eresmech\/files\/2022\/09\/kammotion2e_4.gif\" target=\"_blank\" rel=\"noopener noreferrer\" data-caption=\"\"><img loading=\"lazy\" decoding=\"async\" width=\"550\" height=\"400\" src=\"https:\/\/blog.metu.edu.tr\/eresmech\/files\/2022\/09\/kammotion2e_4.gif\" class=\"\" alt=\"\" \/><\/a><\/div><\/div><div class=\"su-image-carousel-item\"><div class=\"su-image-carousel-item-content\"><a href=\"https:\/\/blog.metu.edu.tr\/eresmech\/files\/2022\/09\/kammotion2e_5.gif\" target=\"_blank\" rel=\"noopener noreferrer\" data-caption=\"\"><img loading=\"lazy\" decoding=\"async\" width=\"550\" height=\"400\" src=\"https:\/\/blog.metu.edu.tr\/eresmech\/files\/2022\/09\/kammotion2e_5.gif\" class=\"\" alt=\"\" \/><\/a><\/div><\/div><div class=\"su-image-carousel-item\"><div class=\"su-image-carousel-item-content\"><a href=\"https:\/\/blog.metu.edu.tr\/eresmech\/files\/2022\/09\/kammotion2e_6.gif\" target=\"_blank\" rel=\"noopener noreferrer\" data-caption=\"\"><img loading=\"lazy\" decoding=\"async\" width=\"550\" height=\"400\" src=\"https:\/\/blog.metu.edu.tr\/eresmech\/files\/2022\/09\/kammotion2e_6.gif\" class=\"\" alt=\"\" \/><\/a><\/div><\/div><div class=\"su-image-carousel-item\"><div class=\"su-image-carousel-item-content\"><a href=\"https:\/\/blog.metu.edu.tr\/eresmech\/files\/2022\/09\/kammotion2e_7.gif\" target=\"_blank\" rel=\"noopener noreferrer\" data-caption=\"\"><img loading=\"lazy\" decoding=\"async\" width=\"550\" height=\"400\" src=\"https:\/\/blog.metu.edu.tr\/eresmech\/files\/2022\/09\/kammotion2e_7.gif\" class=\"\" alt=\"\" \/><\/a><\/div><\/div><\/div><script id=\"su_image_carousel_69d7188004239_script\">if(window.SUImageCarousel){setTimeout(function() {window.SUImageCarousel.initGallery(document.getElementById(\"su_image_carousel_69d7188004239\"))}, 0);}var su_image_carousel_69d7188004239_script=document.getElementById(\"su_image_carousel_69d7188004239_script\");if(su_image_carousel_69d7188004239_script){su_image_carousel_69d7188004239_script.parentNode.removeChild(su_image_carousel_69d7188004239_script);}<\/script><\/p>\n<p>Analytical method of cam profile determination makes use of envelope theory.

An envelope can be defined as:<\/p>\n<p><strong><em>If each member of a family of curves is tangent to a certain curve and if each point of this curve at least one member of the family is tangent, the curve is either a part or the whole of the\u00a0<\/em><u>envelope<\/u><em>\u00a0of the family.<\/em><\/strong><\/p>\n<p>A family of curves with one parameter is in the form f(x, y, c) = 0. c is the parameter. For each value of c we obtain a member of the family of curves.
