The kinematical calibration of the articulated CMM is usually performed using some 3D artifacts. However, 3D artifact is too large and difficult to be handled. So, we tried to use a simple artifact several times and to get the equivalent calibration result to 3D artifact. In this paper, the...
The mathematical modeling method involves the calibration of CMM geometric errors to build a theoretical model and predict the uncertainty for any measurement done according to the model’s assumptions. A comparison method involves the inspection of a calibrated artifact identical to the piece under ...
Either way, the movable features 104 of the CMM 100 manipulate the relative positions of the measuring device 106 and the object 101 (or calibration artifact) with respect to one another to obtain the desired measurement. Accordingly, the CMM 100 can effectively measure the location of a ...
The Crown, Part Number AN-CR is a small lightweight aluminum device that is designed to hold calibration equipment on very small Coordinate Measuring Machines. The overall height is four and one half inches (114mm). It has a three inch (76mm) diameter base, or foot. There is a counterbo...
Registration methods can be classified into two major categories: registration based on material gauges and self-calibration [2]. With the former, coordinate systems are aligned with the help of common feature points. Bradley et al. [3] adopted a reference sphere to combine data from a contact...
there is a fixed reference sphere mount with a sphere and, if necessary, a calibration ring and a glass artifact. To calibrate, the operator just has to place the pallet onto the machine and then start the measuring process. Since all calibration instruments are a part of the pallet, it ...
A method of the volumetric error measurement and calibration of NC machine tools is studied using an artifact method. In this study, a hole-pate is designe... Dal,Geun,Park,... - 《Journal of the Korean Society of Manufacturing Technology Engineers》 被引量: 0发表: 2006年 ...
If the daily check shows an error, the tips are all visually checked for damage and the calibration program for that arrangement is performed. This checks and compensates every tip and index position in the arrangement. I haven't ever seen us use a ring gage check. Wear has never been ...
Validating the error map of a CMM using a calibrated probe including a stylus, the probe capable of rotation about at least one axis, includes placing a calibration artifact on a table of the CMM, the table having an upper surface in an XY plane; positioning a Z-ram of the CMM in a ...
