Surface analysis can also be performed using a single file or dynamically.
CMM operators will create vectors on CAD models using software programs, dynamically select CMM formats, program and simulate each move.
After programming, the operator can perform all the necessary analysis tasks and generate reports.
The text report will provide point numbers, labels, surface descriptions, and can be customized.
The graphic report will display point numbers, labels, alignment benchmarks and deviations in 3D colors to provide complete documentation for any inspection item. "Best-
Fit "analysis of the part will allow for better alignment of the coordinate system, and in many cases one is initially marked out-of-tolerance. Built-
In CAD, functions are also very important to verify the system.
The CAD function allows the operator to visualize, operate, and clean up the 3D CAD model of the inspected part, fixture, tool, or assembly.
Tasks can be performed on the right side of the workshop, such as reversing surface vector normals, moving shield or moving isolation geometry to layers, removing unwanted entities, generating vectors, and even adding or expanding surfaces.
New generation detection coordinate measuring instrument (CMM)
It is a way to collect 3d coordinate data from processed parts and convert information into CAD-usable data.
The surface capacity of the traditional CMM may be from a few inches to a few feet with a tolerance range of 0. 001"and up.
In the past few years, a new generation of testing equipment
Laser Tracker for motor
Navigation and camera systems-
Has entered the market to provide dynamic or non-contact detection functions.
These systems may have a surface area of up to hundreds of feet and can be targeted at large products such as aircraft, ships and construction structures.
Manual 3D CMM, such as digitizer for FARO, Romer, Immersion, brown, and Sharpe, allows users to freely define the settings for collecting points and cross-data
Part of the model.
The basic input device can be manual.
Convert digitizer into a micro scribe for fixed devices such as 3d mouse or CMM.
At the high end of the price range, these devices will automatically collect point data;
Scan the outline of the physical model;
And generate "point cloud" or a series of crossoversections.
The user can control the number of "slice or cut planes", the distance between the intersection points, and the tolerance factor.
At the high end, Leica's new generation laser tracker theLTD500 is an accurate (to 0. 001[inches])

Verification and analysis software verisurf "analysis "(
Verisurf software, Anaheim, CA)
A good example of Windows
Multi-Surface detection and analysis software program based on auxiliary manufacturing quality control.
The software uses data collected from various supported inspection equipment to accurately compare machined parts with 3D CAD models of parts, while greatly reducing the need for full-size 2d drawings.
CAD models can be imported from almost any CAD system, or ifa CAD models are not available, and quality control personnel can quickly create 3D models from blueprints using 2D and 3D CAD drawing tools.
Once the part is measured and the deviation between the 3D CADmodel and its corresponding detection data is analyzed,to-
Explain the point where the terrain color and text report show the tolerance of the parts to and from.
The color legend shows the number of deviations in different shades.
For example, red represents a negative tone (
Blue represents the front (
Set the points within the limits to be displayed in green.
A unique "best fit" feature included in VERISURF "analysis" helps align the coordinates of the checked data with the CAD model, with a maximum of six degrees of freedom.
The software program will continuously rotate the point cloud data on the detection device to the CAD model until the "best fit" is achieved ".
This work enables manufacturers to save parts that they may have previously scrapped by assuming that the parts are out of tolerance.
The company can confirm or verify whether the parts are within the tolerance range and help them to certify whether they meet the iso9001 standard.
"Bestfit" has dozens of options, including the ability to lock any shaft or shaft combination during operation, while allowing the remaining axes to move freely.
In order to simplify the verification process, the help of engineering department is no longer needed to create vectors on 3d models to program CMM.
The "Teach" method allows operators to collect random points using detection devices and bring them into VERISURF "analysis" to automatically create the vector normal required for vector method programming.
The program also supports the "CAD" method in which checkpoints can be created on CAD models in many ways.
For example, an operator can use the mouse to dynamically link to the surface and select the point to be measured;
Or the user can create a grid of points on the surface.
After the point is specified, the software will generate a vector file that can be programmed and formatted for DCC.
In the area of providing open architecture and other integrated approaches, software developers have made significant progress in validation techniques to meet the multifaceted needs of the manufacturing industry.
Now, even in multiple cases of simultaneous use, an unlimited number of different detection devices can be dynamically integrated.
The future of the verification technology depends on the communication, commonality and compatibility of the inspection department throughout the manufacturing environment.
Like mediators, software and hardware companies pass on what we have learned in each department, share our problem-solving skills, expose overlapping efforts, and demonstrate newideas.
By combining all of these processes, consistency and ease of use can only simplify the entire validation process, making it more efficient and profitable for any manufacturing company.
