Tiivistelmä
This thesis was created for quality department at ABB Oy, IEC LV Motors unit. The purpose of this thesis was to create a measurement guideline for the different components of the electric motor for the supplier. This thesis also examined the different methods used to measure the components using coordinate measuring machine. The aim of the thesis was also to evaluate the possible errors in meas urement process and study the different methods used.
The thesis focuses on the measurements of the different machined cast iron parts that are delivered from different suppliers. The examined parts include different sizes of stator frames, D-and N-end shields, and different bearing components.
Measurement tests were made to study the differences in measurement practices that are currently being used. These tests include measurements of geometrical tolerances, forming a cylinder or taking a single circle and differences that come from the amount of measurement points taken from the measured feature.
