“…It, thus, becomes a need to compensate the probe radius before the measured points data can be used. The probe radius compensate method of "produce the offset theoretical probe center surface" can be used in the crown worm measuring (Liang and Lin 2002).…”

The crown worm drive is a new type of worm drive, it is consisting of an internal gear and a crown worm generating by the internal gear surface, and it is characterized with small size yet high-loading capacity. To satisfy the high precision requirement of crown worm tooth surface, a grinding method based on virtual center distance manufacturing principle is proposed and a grinding machine is reformed. A mathematical model was derived to calculate the theoretical probe center surface, and a measuring method is proposed to check the accuracy of crown worm tooth surface. A crown worm sample is manufactured and measured, the results show that the accuracy is 0.079mm on the upside tooth surface and 0.082mm on the underside tooth surface. The study is expected to provide the experimental foundation for the future application of the crown worm drive.

“…Kluczowymi elementami procesu inżynierii odwrotnej są digitalizacja obiektu i tworzenie jego modelu geometrycznego. Proces digitalizacji realizowany jest obecnie najczę-ściej z wykorzystaniem współrzędnościowych maszyn pomiarowych [6], skanerów optycznych [7] lub laserowych [4]. Budowa modelu geometrycznego obiektu koncentruje się w głównej mierze na przetwarzaniu chmur punktów pomiarowych i przetwarzaniu ich w powierzchniowe modele geometryczne odtwarzanych obiektów [1].…”

StreszczenieZaprezentowano metodykę realizacji procesu inżynierii odwrotnej obiektów przestrzennych, która obejmuje następujące etapy: digitalizację obiektu przestrzennego na współrzędnościowej maszynie pomiarowej, budowę modelu geometrycznego obiektu na podstawie przetworzonych wyników pomiarów współrzędnościowych, ocenę dokładności uzyskanego modelu geometrycznego rekonstruowanego obiektu, wytworzenie kopii obiektu z wykorzystaniem frezarki CNC. Proponowana metodyka została zweryfikowana na przykładzie odtwarzania geometrii dolnej części obudowy pilota TV. Słowa kluczowe: digitalizacja, modelowanie geometryczne, system CAD/CAM, frezarka CNC REVERSE ENGINEERING OF THE SPATIAL OBJECTS WITH THE USE OF CMM AND CNC MILLING MACHINES AbstractThe paper presents the methodology of the reverse engineering of the spatial objects. The adopted methodology consists of the following stages: digitalization of a spatial object on CMM, construction of a geometric model of the object based on results of the coordinate measurements, accuracy assessment of the resulting geometric model of the reconstructed object, manufacture of a copy of the object on CNC milling machine. The proposed methodology was verified on example of the reconstruction of the lower cover TV remote control.

“…In our inspection framework, the robot can only know the sphere center coordinates p p i of the probe, and the problem becomes to construct the corresponding relations between these two points. It has been discussed in some studies [9,10], which mostly emphasize on the method to construct a surface and to deduce the normal of the inspection points.…”

This paper presents an efficient method for rigid registration of 3-D point sets, which intends to match the feature points inspected using touch probe with the points on designed CAD surface. The alignment error is defined as the least square problem, and the sphere radius of the inspection probe is considered. In this framework, the matching problem is converted into acquiring six Euler variables problem by solving nonlinear equations. Thus, a matrix transformation of parameter separation is presented to get the approximate resolution. Finally, iterative cycles are provided to calculate the nearest points on designed surface corresponding to the inspection points. Experiment verification is realized for the presented surface matching method of robot inspection system.
