CMM Inspection without a Master Part

By | 2017-12-22T08:21:20+00:00 August 30th, 2017|Categories: 3D Scanning, Tech Tips|0 Comments

Have you ever needed to inspect parts in a CMM, without having a master part? Automated CMMs can be a great time saver when inspecting parts on the shop floor. Traditionally, a master part is measured to generate a master data set. The same routine is then automated and used to measure each production part. Each production data set is then compared to the master data set to determine the actual size of the part and whether it is within user defined tolerances. But what if you don’t have a master part available, or one that was closely produced to drawing nominal? This is where the CMM Master can be a great solution. The CMM Master, based on the Renishaw Equator platform, is a portable, automated CMM, calibrated for high production shop floor inspection. In conjunction with the Verisurf software, it is volumetrically error mapped to increase the traditional Renishaw Equator accuracy down to .0005”. Here you see the CMM Master running an automated measurement routine. When it’s done, it automatically generates a date and time stamped report. One thing that makes the CMM Master unique is that a master part is not required in order to perform on the [...]

Simultaneous Synchronized Scanning

By | 2017-12-22T08:35:53+00:00 June 28th, 2017|Categories: 3D Scanning, Tech Tips|0 Comments

This blog post is going to show you how to scan a mid-size part with tiny features. When scanning a model, you're usually faced with the decision of using a scanner that either has a large scan envelope and good resolution, or a scanner that has a small scan envelope with high resolution. But what if you needed the best of both worlds, that is, to capture both a larger part with small fine details? One way to achieve this is to run two scanners simultaneously, and synchronize them to the same turntable. The Geomagic's Capture scanner has an accuracy of about .0035" and is good for scanning mid-size objects. When scanning a model, it's able to pick up the majority of the geometry, but the small fine features get washed out. This is where simultaneous synchronized scanning comes in. You can synchronize Geomagic's Mini-Capture scanner to the same turntable that is aligned to the Capture scanner. The Mini-Capture has a smaller scan envelope, but an impressive accuracy of about .0015." This is what is needed for capturing the fine details on a small part. To run the scans simultaneously, press the Scan button and the turntable moves. Each scanner [...]

Geomagic Design X

By | 2017-12-22T08:39:04+00:00 June 21st, 2017|Categories: 3D Scanning|0 Comments

With Geomagic Design X software you can easily produce a fully featured, editable, native CAD model, directly from a scan. What is Design X? Design X software is a tool that enables you to recognize geometrical features on a scan, utilize them to create CAD features, then transfer that tree of features directly out to the feature tree of your CAD system. Let’s break this process up into three stages: Auto Segment, Feature Extraction, & LiveTransfer to CAD. Auto Segment Auto Segment in Design X allows you to split the polygonal mesh into regions, created by grouping adjacent polygons with similar curvature. As you hover your mouse over each region, Design X displays the geometric shapes that have been identified, like a plane, cylinder, cone, etc. Feature Extraction Once you have all your geometrical regions mapped out, your next step is to extract and create the CAD sketches and features. To do this, start a mesh sketch either directly on a planar region, or a CAD plane, then offset the plane to the location where you want to extract a slice of the polygonal mesh. At this point you will be creating your 2D Sketch entities. You can use that [...]

Reverse Engineering Sheet Metal to a Flat Pattern

By | 2017-05-08T09:31:52+00:00 May 8th, 2017|Categories: 3D Scanning|0 Comments

Today we are going to talk about how to reverse engineer a used sheet metal part back to its original flat pattern. This can be challenging at times, since sheet metal parts tend to bend and distort with normal use. Geomagic Design X can assist you in interrogating the geometry of the part, and reverse engineering it back to the original un-warped shape. After scanning the part, you can import the resulting point cloud into Geomagic Design X and clean up scan file. Next, convert the points to a polygonal mesh, and Auto Segment the mesh. By auto-segmenting the mesh, Design X creates regions made up of polygons that have similar curvature values. Thus, it becomes easy to identify and interrogate geometric shapes. You can then use these regions to create and establish your Datums. At this point, you can start reverse engineering your CAD file by tracing over the mesh profiles, and creating real 2D and 3D geometry. Design X keeps a CAD history tree of everything you’re doing. When you have captured enough information from your polygonal mesh, you can then export your work to your CAD software. In CAD, you can complete your design by converting your [...]

Improving Aesthetics of a Scanned Mesh

By | 2017-04-10T09:10:21+00:00 April 10th, 2017|Categories: 3D Scanning, Tech Tips|0 Comments

In this blog post we will discuss how to improve the quality of your STL to produce better 3D Printed parts. The STL, or Stereo Lithography file format, is widely used for rapid prototyping, 3D Printing, and CAM. An STL file describes the surface geometry of a 3D object by triangulating the vertices on each face of the object. At times though, the STL file may contain errors, small holes, imperfections, and blemishes as shown below. These imperfections may happen if the file was produced by scanning a used or worn part. So how do you go about modifying the STL file, and optimizing it, to produce a better quality 3D Printed part? One solution is to use Geomagic Wrap. It has many powerful easy-to-use tools that enable you to improve the cosmetics of the model by modifying the mesh structure underneath. Let me show you a few of these tools. First, you can easily remove the spikes, or pyramid shaped polygons from the mesh and smooth them out by using the Spike Removal tool. Next, for the sections of the model that are really sloppy, you can simply delete the polygons by using the Manifold Open tool to quickly [...]

The Go!Scan 3D portable handheld scanner delivers high-quality 3D models with reliable measurements. It weighs a little over 2lbs and has an ergonomic grip providing simple ease of use. Similar to Creaform’s HandyScan, it has a USB and power cable which connects directly to your laptop or workstation. Upon setup, typical objects can be scanned in 5 minutes or less. The Go!Scan operates with a white light (LED), which is great for capturing organic shapes in full HD color. This scanner particularly excels at capturing both shapes and textures simultaneously, for example colors, skin tones, fabric and material patterns, and more. White light is also safer for the scanning of humans than laser units. A big benefit of this scanner is that it is self-positioning, meaning it typically doesn’t require targets for setup. Simply point and shoot and you can even move both the part and the scanner during scanning. It has an accuracy of up to 0.1 mm and its file outputs are compatible with all your popular CAD software. Some popular applications include human body and facial scanning, heritage preservation, arts & architecture, computer graphics, and visual effects. But it can also perform applications for design & manufacturing, [...]

Inspect Freeform Surfaces

By | 2017-01-20T09:01:43+00:00 January 20th, 2017|Categories: 3D Scanning|0 Comments

There are various types of dial indicators and other manual gauges that can be used to inspect freeform surfaces and determine if they are within tolerance. However, inspecting surface profile tolerances can be quite challenging when you are measuring freeform surfaces. One solution for this scenario is utilizing Verisurf software along with the CMM Master. In Verisurf, you can define the Geometric Characteristic, the Tolerance Zone Size, and add the Datum References called out on the manufacturing drawing. Next, add a surface grid of points on that freeform surface. The probe will scan and analyze each one of these points as it sweeps across the surface. You can control the density of the scan points, as well as the path direction the probe will take. Once you finish programming the probe path, use the CMM Master to inspect it. The probe then follows the automated repeatable path created in the Verisurf software, and quickly scans and collects the data from each grid point. Once this process is done, you can easily produce a First Article Inspection report per AS9102 REV B standard, or output a PDF with the tolerance information. As you can see, inspecting a freeform 3D surface just [...]
