Abstract
In case of coordinate machines that use CAA correction matrix, the issue of kinematic errors analysis may be based on the determination of residual error distribution. Temperature changes have an impact on CMM kinematic structure, which may cause the differences in the map of residual errors. As for today, the residual errors were analysed only for the reference temperature. No research was undertaken on the residual errors changes depending on the temperature variations. This paper presents the experiment aimed at residual errors analysis and resulting errors distributions for different temperatures.

Today, in the era of continuous development of technology and industry, it becomes even more important to ensure adequate quality of manufactured products
Coordinate Measuring Machine (CMM) kinematic errors were the subject of a number of studies [4, 5] which resulted in the development of models of machine errors, for example full rigid body or reduced rigid body models
Since most of the currently used machines, utilize CAA correction system, the issue of CMM kinematic error analysis can be transferred to the analysis of residual errors
Summary
In the era of continuous development of technology and industry, it becomes even more important to ensure adequate quality of manufactured products. The main tool of CMT is Coordinate Measuring Machine (CMM). The models developed so far assume machine functioning at reference conditions (temperature of 20°C). Developed at LCM virtual machine consists of two main modules: one responsible for machines kinematics modelling and one devoted to probing systems functioning.
