How does reverse engineering a CAD model work?
Reverse engineering a CAD model typically involves 3D scanning and measuring a part to gather data, which is then used to create a new digital model in CAD software. Reverse engineering a 3D CAD model typically begins by measuring and inspecting a part. This measurement data, collected through methods like 3D scanning, CMM,…
How accurate are CMMs?
How accurate are CMMs? CMMs are the most accurate way to measure a wide range of features. Their accuracy is expressed as a linear formula, proportional to the length measured. Typically this is measured in microns. Understanding CMM Accuracy Specifications A calibration certificate for a CMM typically includes multiple forms of the MPE…
What is a CMM?
Coordinate Measurement Machines (CMMs) are used to automatically measure points on a part to verify that its dimensions and geometry match the design intent and drawing specifications. There are many variations and types of CMMs, however the most common type is the traditional bridge CMM. This has three linear axes which move perpendicular…
What is 3D Scanning & Modelling?
Introduction 3D scanning is one of the fastest growing technologies of the 21st century. 3D scanning is the process of collecting data from real world object to generate digital models. Since 2001 when Google used photogrammetry to produce a fully interactive 3D model of our planet, and Microsoft releasing the Kinect in 2010,…
What is the Production Part Approval Process (PPAP)?
The Production Part Approval Process (PPAP) is a standardised process used in the automotive supply chain to ensure that a part’s design and specification is properly communicated, implemented, and documented. The Production Part Approval Process (PPAP) was developed by the Automotive Industry Action Group (AIAG) as a part of the Advanced Product Quality Planning (APQP)…
What is a Measurement System Analysis / Gauge R&R Study?
Gauge R&R is the most common Measurement System Analysis (MSA) method used to practically determine the measurement uncertainty of equipment and inspection processes. A Gauge Repeatability and Reproducibility Study, commonly known as Gage R&R or GR&R, is a Measurement System Analysis (MSA) tool used in metrology and the inspection industry to determine the…
What is a First Article Inspection Report (FAIR)?
First Article Inspection (FAI) is the process of verifying that a new or modified production process meets the manufacturing specification, usually detailed in a technical or engineering drawing. Once a production process is established, it is necessary to verify it has been setup correctly. A first article inspection report enables manufacturers to establish…
