Monitoring coordinate measuring machines by calibrated parts
Coordinate measuring machines (CMM) are essential for quality assurance and production control in modern manufacturing. Due to the necessity of assuring traceability during the use of CMM, interim checks with calibrated objects carried out periodically. For this purpose usually special artefacts like standardized ball plates, hole plates, ball bars or step gages are measured. Measuring calibrat...
متن کاملPrediction of residual stresses in injection moulded parts
For automotive plastic parts, mostly used for interior assemblies, there is a clear demand of an increased accuracy of the simulation model. One crucial input for the simulation model is the correct material data. Based on test data, it is known that the dynamic material properties of a plastic part can differ significantly from the material data given in the data sheet (which is based on a spe...
متن کاملa new method for measuring perforated surface by coordinate measuring machine (cmm)
nowadays cmm machines are widely used in surface measurement and inspection. as inspection results from cmm machine are obtained by the means of measuring surfaces with direct contact, they are more precise than non-contact method (like optical measurement). however, cmm machines give more reliable and accurate results rather than non-contact methods but also these results come with error when ...
متن کاملError Analysis of Effects of Workpiece Coordinate System Misalignment When Measuring on a Coordinate Measuring Machine
Ever since the introduction of coordinate measuring machines (CMMs), their measuring accuracy has been studied. Much research work has focused on the accuracy characteristics of the measuring system, e.g. the static errors and dynamic errors of the machines. However, the additional error sources can be introduced when a measuring coordinate system is set up. This paper describes how to analyse ...
متن کاملArticulated Arm Coordinate Measuring Machine Calibration by Laser Tracker Multilateration
A new procedure for the calibration of an articulated arm coordinate measuring machine (AACMM) is presented in this paper. First, a self-calibration algorithm of four laser trackers (LTs) is developed. The spatial localization of a retroreflector target, placed in different positions within the workspace, is determined by means of a geometric multilateration system constructed from the four LTs...
