Magna Automotive Testing (MAT), located in MI, Livonia, Michigan, USA, has a simple mission: to make cars and trucks move better and better, both mechanically and ergonomically, and to ensure that they The parts are working well. MAT is the commercial testing organization of Intier Motors, which solves manufacturing difficulties for the three major automakers and also serves the manufacturing decision-making of the Group.
The MAT has a wide range of work and can detect everything from the prototype of the vehicle to its manufacturing process. Within a given week, they can undertake to test a lift gate, digitally capture the floor plan (layout structure) inside the car, complete a quality analysis of the weld line, reverse engineer the structure without the blueprint, or perform a work on the fixture. Tasks such as critical dimension correction.
The core of MAT work is reflected in fast and accurate measurements. With reliable 3D data, you can measure the accuracy of each component's machining, the 3D layout of the workpiece's mounting points, and even act as a troubleshooter for OEMs (resolving original equipment manufacturers).
Accuracy, simplicity, flexibility
Ten years ago, Intier Motors used traditional gages to acquire 3D data, but those tools were inaccurate and prone to read errors, and thus did not solve the problem that can only be determined by measurements with very small errors. In addition, the details that engineers need far exceed the data they get from mechanical tools. For example, three planes can determine a plane, but a surface requires 500 or more points to accurately represent a slope or bow change. In addition, engineers need to be able to operate in a digital environment, and it is in this digital environment that automakers are taking control of the development of new vehicles.
Conventional coordinate measuring machines are capable of measuring density, but they must be constantly adjusted to measure the density of different parts, so the shape that can be measured is limited. In addition, traditional CMMs cannot be moved, and anything that needs to be measured must be moved to where it is placed.
"By breaking the measurement range of traditional instruments, it is increasingly important for us to measure the accuracy of small size changes," Todd Hovey, the leader of the quality monitoring team responsible for MAT, explains, "Because much of our work needs to be done now, usually Beside the machine or in a model workshop."
In the early 1990s, MAT engineers discovered that FaroArm's 3-D digitizers were able to overcome the shortcomings of mechanical measuring instruments. This is a portable arm-type digital measuring machine that captures any point within its range of ball probes to an accuracy of 0.0005 inches. The measurement method is very professional, it uses the Arm tip stylus to detect the surface of the part, mold or chassis. A CAD-compatible CAM2 software is installed on the laptop, which records the points tested on the surface of the object as continuous or discrete lines. As more and more points are assembled, a digitized image of the surface of the object appears on the computer screen.
FaroArm
Due to its high precision and portability, the FaroArm has become an authoritative tool for aerospace, automotive and OEMs manufacturing. And because it can mark the size of almost all surfaces in just a few minutes (rather than the lengthy programming required by traditional coordinate measuring machines), the processing of the product is no longer rigid and does not require complicated investigations.
Hovey affirmed: "When using the FaroArm, in most cases, the rapid collection of data completely reduces the cost of the collection process."
