- Abstract:
- The main purpose of this work is to investigate the errors on secondary surfaces generated to joint free form surfaces of complex parts measured with Coordinate Measuring Machines (CMM) and modeled with CAD techniques. The approach involves the measurement of a complex part and fitting using NURBS curves and surfaces. The errors were determined by difference between determined points on secondary surfaces and fitted CAD surface.
