Fusion 360 has just recently introduced additional functionality through the manufacturing extension, including Steep and Shallow and Surface Inspection. I took those tools for a spin to machine this mudguard tooling on a Hermle machining center in our Birmingham Technology Center in the UK. Watch the video below to see the full process and how the manufacturing extension helped me achieve a high-quality finish on the final part.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><iframe loading=\"lazy\" class=\"aligncenter\" src=\"https:\/\/www.youtube.com\/embed\/iBTm7NnuNQA\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><span data-mce-type=\"bookmark\" style=\"display: inline-block; width: 0px; overflow: hidden; line-height: 0;\" class=\"mce_SELRES_start\">\ufeff<\/span><\/iframe><\/p>\n<p>&nbsp;<\/p>\n<h2><strong>Steep and Shallow<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<p>The manufacturing extension includes several new manufacturing tools, but I want to focus on Steep and Shallow and Surface Inspection. I particularly want to focus on the benefits of using them in your manufacturing process. Steep and Shallow is a new 3D finishing toolpath that some of you may recognize from PowerMill. In fact, Steep and Shallow is PowerMill\u2019s 3rd most used CAM strategy. Steep and Shallow automatically recognizes the steep and shallow regions on freeform geometry, optimizing the toolpath for each region and combining them to produce a single toolpath.<\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-11486\" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/full-toolpath.png\" alt=\"full steep and shallow toolpath on mudguard mold tool\" width=\"600\" height=\"337\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/full-toolpath.png 1912w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/full-toolpath-300x169.png 300w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/full-toolpath-1024x576.png 1024w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/full-toolpath-768x432.png 768w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/full-toolpath-1536x864.png 1536w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/full-toolpath-284x160.png 284w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/full-toolpath-382x216.png 382w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>On its face, this seems like a pretty simple task. It also seems achievable by manually combining two separate strategies, which is exactly what I did before. When machining shallow areas on a part I would always tend to use one of the following toolpaths: where fillets where present I would likely use a Scallop style strategy; where no fillets were present (i.e. sharp corners at the base of a pocket) I would tend to use a Parallel strategy. When machining the steeper areas of the part, Contour was always in my kit bag. Contour steps down steeper areas and ultimately gives me a decent quality toolpath for areas such as pure vertical walls.<\/p>\n<p>&nbsp;<\/p>\n<p>Steep &amp; Shallow combines these individual toolpaths into a single compounded strategy, and I discovered several additional benefits along the way.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>Continuous Spiral for Improved Surface Finish<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<p>When using Scallop option on shallow areas, the new Steep and Shallow strategy has the option to use continuous spiral. This means the tool does not have to perform a transition move between passes on shallow regions. A minor benefit is reducing cycle time with less overall moves. But the biggest benefit here is that with no steps between passes, there are no marks where the tool transitions between passes.<\/p>\n<p>&nbsp;<\/p>\n<div id=\"attachment_11477\" style=\"width: 610px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-11477\" class=\"wp-image-11477 \" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/normal-scallop.png\" alt=\"normal scallop toolpath on shallow area with disconnected passes\" width=\"600\" height=\"454\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/normal-scallop.png 660w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/normal-scallop-300x227.png 300w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><p id=\"caption-attachment-11477\" class=\"wp-caption-text\">Normal Scallop with separate passes<\/p><\/div>\n<p>&nbsp;<\/p>\n<div id=\"attachment_11475\" style=\"width: 610px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-11475\" class=\"wp-image-11475 \" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/2-continuous-scallop.png\" alt=\"\" width=\"600\" height=\"454\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/2-continuous-scallop.png 660w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/2-continuous-scallop-300x227.png 300w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><p id=\"caption-attachment-11475\" class=\"wp-caption-text\">Continuous Scallop with no seam between passes.<\/p><\/div>\n<p>&nbsp;<\/p>\n<h2><strong>Corner Smoothing and Automatic Cusp Removal<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<p>Notice that our new Steep and Shallow toolpath contains no sharp corners at all. The Smooth Offsets option rounds the sharp corners from the toolpath, which has two major benefits. Generally speaking, the machine tool control is almost always looking ahead while executing a toolpath. When the control sees a sharp corner coming up in a toolpath, it automatically reduces the programmed feedrate so the cutting tool can change direction at the sharp corner. This does two things. First, when the feedrate slows down, the cutting tool stops deflecting which can result in a dwell mark on the part. Second, when feedrate reduces automatically, machining cycle time increases. Eliminating all sharp corners from the toolpath smooths out machine motion, making the machining cycle time faster and improving surface finish.<\/p>\n<p>&nbsp;<\/p>\n<div id=\"attachment_11477\" style=\"width: 610px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-11477\" class=\" wp-image-11477\" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/normal-scallop.png\" alt=\"normal scallop toolpath on shallow area with disconnected passes\" width=\"600\" height=\"454\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/normal-scallop.png 660w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/normal-scallop-300x227.png 300w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><p id=\"caption-attachment-11477\" class=\"wp-caption-text\">Normal Scallop with separate passes<\/p><\/div>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<div id=\"attachment_11476\" style=\"width: 610px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-11476\" class=\" wp-image-11476\" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/4-smoth-w-cusp-removal-scallop.png\" alt=\"\" width=\"600\" height=\"454\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/4-smoth-w-cusp-removal-scallop.png 660w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/4-smoth-w-cusp-removal-scallop-300x227.png 300w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><p id=\"caption-attachment-11476\" class=\"wp-caption-text\">Scallop with Smooth Offsets and Remove Cusps and Junctions enabled.<\/p><\/div>\n<p>&nbsp;<\/p>\n<p>Also, notice that there is a centreline (centerline, for those of you in the US) trace as the final cutting action in the Steep and Shallow toolpath. The centreline cut passes over all of the corners to remove the tiny cusp of material left where the cutting tool smoothly changed direction on the scallop toolpath. The increased distance between the passes at the corner means the cusp is slightly taller, and this final pass reduces those remaining cusps, again improving final surface finish quality.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>Wall Clearance with Parallel<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<p>We\u2019ve taken a look at several benefits associated with using a Scallop to machine shallow areas \u2014 but what about Parallel? As we mill the bottom of this deep pocket, shown in the screenshot below, the tool approaches the side wall at the end of each pass. With a traditional Parallel, this may cause an issue as the tool could engage with the wall of the pocket. That engagement creates a mark on the finished surface and may cause significant wear or damage to the tool.<\/p>\n<p>&nbsp;<\/p>\n<p>The new Steep and Shallow toolpath strategy automatically detects walls and includes a Wall Clearance parameter that ends the parallel passes slightly short of the steep wall by the entered distance. This helps avoid the tool touching the wall of the pocket, resulting in a better surface finish especially on the steep faces of the part.<\/p>\n<p>&nbsp;<\/p>\n<div id=\"attachment_11478\" style=\"width: 410px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-11478\" class=\"wp-image-11478\" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/parallel-no-wall-clearance.png\" alt=\"Steep and Shallow Parallel Passes with no Wall Clearance\" width=\"400\" height=\"298\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/parallel-no-wall-clearance.png 801w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/parallel-no-wall-clearance-300x223.png 300w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/parallel-no-wall-clearance-768x571.png 768w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><p id=\"caption-attachment-11478\" class=\"wp-caption-text\">Parallel Passes with no Wall Clearance<\/p><\/div>\n<p>&nbsp;<\/p>\n<div id=\"attachment_11479\" style=\"width: 410px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-11479\" class=\"wp-image-11479\" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/parallel-wall-clearance.png\" alt=\"Steep and Shallow Parallel passes with Wall Clearance\" width=\"400\" height=\"297\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/parallel-wall-clearance.png 801w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/parallel-wall-clearance-300x223.png 300w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/parallel-wall-clearance-768x571.png 768w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><p id=\"caption-attachment-11479\" class=\"wp-caption-text\">Parallel passes with Wall Clearance<\/p><\/div>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>Automatic Parallel Angle<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<p>Another benefit to the Parallel shallow strategy in Steep and Shallow is automatic angle calculation.

Now, Steep and Shallow includes a built-in overlap value, which overlaps the strategies used on the steep and shallow regions by the given amount. Without the overlap value, the toolpaths for the steep regions and the toolpaths for the shallow regions step over at exactly the same edge. This can result in small misalignment, creating a seam on the surface finish of the machined component. By entering an overlap value, the boundary expands slightly so the steep and shallow regions step over in different locations, minimizing dwell marks.<\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-11482\" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/overlap.png\" alt=\"Steep and Shallow overlap distance blending the steep and shallow strategies\" width=\"599\" height=\"181\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/overlap.png 983w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/overlap-300x91.png 300w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/overlap-768x232.png 768w\" sizes=\"auto, (max-width: 599px) 100vw, 599px\" \/><\/p>\n<p>&nbsp;<\/p>\n<h2><strong>Surface Inspection<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<p>Now that the part has been finished, or even semi-finished, it needs to be inspected to understand how accurately it has been machined. In-process inspection of a part is extremely useful in determining how much material is left on the part after a semi-finishing operation. This information helps drive decisions like making adjustments to the tool offsets or toolpath itself. Inspection is also valuable after the final finishing passes to determine whether the part is in tolerance, needs re-machining, or has too much material removed. The results help with valuable downstream decision-making before removing the part from the machine, and accurate re-machining becomes much more difficult.<\/p>\n<p>&nbsp;<\/p>\n<p>With Surface Inspection, I can select the critical locations on the original CAD model where I want the probe to check the in process machined part. Selecting these points on the CAD model tells Fusion 360 where to probe. Fusion 360 compares the point measurement captured by the probe on the machine tool to the expected position of point on the CAD model. Using those results Fusion 360 can tell me if the probed location is high (meaning there is additional material on the part to be removed), low (meaning that maybe we\u2019ve machined away too much material and so we have a problem), or is within tolerance (meaning that we may not need to perform any more machining operations on that region of the model).<\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-11485\" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/probing-ope.png\" alt=\"surface inspection results shown on model and in results table\" width=\"599\" height=\"337\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/probing-ope.png 1920w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/probing-ope-300x169.png 300w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/probing-ope-1024x576.png 1024w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/probing-ope-768x432.png 768w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/probing-ope-1536x864.png 1536w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/probing-ope-284x160.png 284w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/probing-ope-382x216.png 382w\" sizes=\"auto, (max-width: 599px) 100vw, 599px\" \/><\/p>\n<p>&nbsp;<\/p>\n<h2><strong>Surface Inspection Results<\/strong><\/h2>\n<p>&nbsp;<\/p>\n<p>Fusion 360 displays the results of the in-process probing operation in two ways: on the part as colorful dots where green indicates within tolerance, red is remaining material, and blue is less material than expected, and in the results window. These results allow us to make very important production decisions before we continue to manufacture the part. For example, if the results show there is less material on the part than required, we can decide to scrap the part before investing additional time and resources. Alternatively, if there is less material than expected but there is still material to be removed \u2013 so the part is not scrapped, but is also different than expected \u2013 we can check the accuracy of the setup and make any necessary adjustments before we continue machining.<\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-11484\" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/probe-results_all-green.png\" alt=\"\" width=\"600\" height=\"307\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/probe-results_all-green.png 1920w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/probe-results_all-green-300x154.png 300w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/probe-results_all-green-1024x524.png 1024w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/probe-results_all-green-768x393.png 768w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2019\/07\/probe-results_all-green-1536x786.png 1536w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>Surface Inspection, like any probing functionality, requires a post processor that supports it.
