According to the Yu Zhang, this is the second technique to the engineering. The case study analysis focuses on the reverse engineering of the application in engineering. The application is developed using the CAM and CAD software to make the measurements of the coordinates of the machine. It involves the measurement of the data of the physical objects by scanning them. The engineering in reverse uses the principle of the design and manufacturing with the aid of the engines using diesel. The reverse engineering in this process is known as digitization and reconstruction with the aid of the CAD software into NC machines as described with the paper.

The data obtained from the measurement using the die's geometric to determine the shape in conjunction with the CMM and the KUM software defines the measurements which are in the linear mode when scanned. The CMM software automatically measures the number of points on the surface to find the change on the curvature of the objects. The advantage with the CMM software is that it measures up to 1600 points on every scan of curves.

The machine tracing process is usually structured with the sequences of points in line structure and number of pints which are large. The analysis of the Zhang's system gives programs which is self-developed which are realized through the transformation of the data information which is measured in a format that the KUM and CMM understands. The measured data is firstly transformed in a format which is universally acceptable to the software format. Eventually, the transformed data is hence processed and filtered using visualization tools and techniques. The data is therefore processed directly using the CAD software for creation. Also, the CAD software reconstructs to reverse into its completion, with the NC process planning using machines to generate the manufacturing the application with the location. The NC machine is finally died when the CAD software is used.

Data Acquisition with Non-Contact Techniques

The Optical techniques captures the shape of the growing and broadest which is probably having the contact techniques popularity. It therefore gives a reason of rapid rates acquisition. The important categories for the optical methods are grouped into five which are time of flight, stereo analysis, laser triangulation and interferometers. The different principles that are applicable in this section are distinguished as follows.

The Laser Triangulation technique is defined as a method that uses the angles and location for photo sensing equipment's and light sources to determine the position. The light source with high energy is projected and focused to the preferred surface at an angle which is pre-specified. The device which is photosensitive preferably the video camera senses the surface of the with the aid of reflection which gives the triangulation of geometrics for the distances and angles to determine the reference plane from the relative surface point position to be calculated. Eventually, the source of light and camera produces the scans of surfaces in multitude having mounted the cameras on the travelling platforms. The relative measurements from the scans are directly proportional to the surface position. The various source of light with high energy can be used, however, the laser are preferred since they are common.

Additionally, triangulations are in a position to capture data with fast rates. The resolution is therefore determined with the accuracy of photosensitive devices from the distance between the scanner and the surface. According to Motavalli, he states that the reverse engineering in the current state is based on the laser triangulation. Furthermore, there is a discussion of the current system of laser triangulation which is used to obtain data of the facial surfaces and the shapes. The measurement of the coordinates using the machines to determine the laser triangulation is analyzed and presented by Mod jarred. This technique gives a wide case study methods analysis, limitation and approaches of the triangulation.

The measurement of distance using the time of light sensing with aid of beams of light emitted gives the method of classification of the system works. The implementation methods given are based on the pulsating beams and on lasers. For instance, the time of flight uses the laser range finders to determine traveled distance in collaborations with the stereo analysis which gives the landmarks relative to the locations positions which related to the multiple images.

The Interferometer technique helps to determine the measurement of the wavelength with the use of interference patterns. The technique can be of importance since it gives accurate measurement of the methods. It is because the wavelength of the visible light has nanometers which are hundreds in the order, which for that instance the applications reverse engineering measurements of distance is between the range centimeters and meters. According to this principle, electromagnetic spectrum parts can be used. In implementation process, light as a source of high energy helps for the provision of both the reference beam and the monochromatic light beams to probe the reflected light from the objects. Moring explains the calculations of time of flight using the range finder. The Current information articles give additionally information on the performance and accuracy in-depth from the analysis results of the range finder in time of flight.

The Structured lightning of the image surface position and hence is involved from the pattern projection of light, to capture an image from the reflected surface and the pattern. The analyzed image gives the coordinate points of the data which is determined on the surface. There is also a method which is popular to the light structured on the shadow, where it gives the contour lines light having projected to the surface and the interference pattern. The analyzed contour lines which have been obtained help to find the distance between lines in the captured images. However, the height of the surface and surface coordinate's points gives the proportional distances to the specified points. Large amounts of structure lightning data is acquired from the single frame image, however, the analysis of position data determines the complexity of data. Furthermore Pennington and Will are used to find the projected grinds of objects on the surface and hence find the locations points. The approaches to these similar stripes are used to for multiple images and light.

The final technique that is used for optical shape image capture is the stereo image analysis. There is some similarity for this technique to the structured lightning in form frames to determine and analyzed the coordinate data. According to this analysis the patterns does not rely on the projection patterns. It eventually rely on the pairs of stereo in order to provide additional information which helps to determine the coordinate and height position. The technique is known as the passive technique since it does not use a similar structure to the lightning structured. Instead, the active technique is differentiated from the passive technique by the data acquisition through the artificial light. The landmarks and the pair image give the correlation for the images that are within the difficult image methods and those which are active are the ones preferred. There are other analyses of the stereo images which focus on the lightning techniques approach, which are instead compared to images with 3D model. The shaded images are however modified using a model which gives a match of the images to the actual objects. Furthermore, the pattern intensity of the images gives the information to the coordinates.

The acquisition of data methods in the final type always determines the acoustic, which reflects the sound on the surface, the magnetic which the surfaces in the magnetic field attracts each other and on the other hand the hybrid which gets into either contact or non-contact. According to the acoustic techniques the measurement of distance is in decades that are used. Occasionally, the sonar is widely applied for this purpose. The cameras often gives focus automatically to the acoustic method while finding the range. Moreover, the time of flight of the method is essential on the surface reflected against the source of sound and difference in the surface and sound in order to find out the speed of sound. The focus points to the locations are determined from the acoustic interference which might be a problem. The ultra sound devices which are used in dynamic imaging in places where transducers capture the objects internally from the material data can be swept at the cross-sectional of the object.

The measurements of the magnetic field, which incorporates the sensing the magnetic field strength from the source. The magnetic fields of the magnet are usually used to determine the orientation and location of the stylus in the magnetic field. The record for the specific data points allows a trigger of records to the positional stylus point of concern. The applications in the similar magnetic allow the measurement of the ultra sound properties of material internally. The atoms of the materials to be measured in the MRI give the response of active atoms.

In conclusion, the data acquisition that are measurable with the methods gives an interaction of the materials either internally or the surface in the following phenomena sound, light, magnetism and the contact with physical surface. The operations of the phenomena speed to the actual speed of the sensor devices gives a determination to the data acquisition speed. The amount of analysis for the sensors varies with type needed to compute the data measured and its accuracy.

Reverse Engineering Hybrid and Non-Contact Techniques Applications

According to the researches that have been carried out for the non-contact technique are those of Tsai and Fan. The measurement of the current system involves the two cameras of CCD, three axis motion and line laser motion. The non-contact analysis for the engineering purposes which involves the mathematical techniques result to direct errors having scanned the optical works setup. Measurements analyzed from the objects in free form profile. The results may be final for matching of the free form images for the accuracy and sufficient efficiency.

The non-contact effects in the system are ambient in the lightning explanations. The measurement of the system may be either ambient or not which depends on the objects lightning color which are projected towards light of the surface. According Clark summary of the laser light projects system, which explains about the unwanted frequencies which are filtered away. When a white light is projected hence there is no particular frequencies are to be blocked. It therefore means that the information that is measured is the once being carried. Otherwise, its gives the ability of the laser based systems with the based systems that are in white light.

Additionally, Clark also explains the results of the water pump model. Both non-contact system and contact system are scanned by the water pump. Eventually, a comparison is conducted based to the quality service and the cloud point data is retrieved. He goes ahead and explains how the non-contact regarding the inspection of the advanced surface and software techniques provides sufficient analysis report from the design process in mechanical....
