The steering wheel is a complex assembly of discrete components mounted together.
Through the use of some positions, the profile is much more skewed than the original.
Examination of such deviations and the design of checkpoints becomes difficult for experts.
The reason is: the size of the clusters are large, many parts are assembled together, through the process of use will appear many complex shapes are worn abrasion failure to keep the desired status to be able to use the type of ruler Measured universal, or need specialized equipment complex measurement contact directly takes a lot of time ...
With the reverse design solution, the math is much easier.
Since all the details, clusters will be digitized, everything will be resolved on the computer for quick and accurate results.
Reverse design stages:
Reverse engineering in the direction of automation is usually divided into three stages: surface sampling (3D surface scans) with 3D scanners / data processing and modeling on CAD software such as Geomagic / application.
The sampling period is the digitization of the sample surface by the type of measuring device. The types of scanner coordinates are chosen according to the shape of the detail, precision requirements, detailed materials, detailed dimensions, etc. The two most common types of coordinate measuring devices today are the device non-contact measurement and contact measurement equipment. Typical of these machines are laser scanners and coordinate measuring machines (CMMs). In this phase the coordinate measuring device will receive the geometric data of the object in the form of the coordinates of the points (x, y, z), and then the points on the object surface are described. "point cloud".
This is followed by the data processing and modeling phase, which uses two software packages (grid automation over all data points) and modeling software. 3D (capable of modeling curves, NURBS curves, building CAD designs from the point mesh model through user interaction with the software interface).
Finally, the application phase, the design model can be fine-tuned, optimized by CAE analysis methods, or transferred to the mold design phase of the product and finally export design data in the form technical drawings.
Direct design data can be used for production by transferring the CAD model to the CAM software for CNC machining, or to STL data for rapid prototyping.
