This paper presents an measurement and analysis system of sheet metal parts with large and complicated curved surfaces used widely for manufacturing applications. For such sheet metal parts, which is characterized by a great volume, a big area, deforming easily and its loading and unloading can be difficultly, the required accuracy and rigidity of the system are critical features. The purpose of the...
Inspection of parts is a requirement to assure quality and to reduce manufacturing costs and rework. This paper presents an inspection system of characteristic of sheet metal parts with large and complicated curved surfaces used widely for manufacturing applications. Sheet metal parts with large and complicated curved surfaces are distorting easily, loading and unloading difficultly. It is very difficult...
Measurement of free-form surfaces is a requirement to assure quality and to reduce manufacturing costs and rework. An on-line measurement system combined coordinate measuring machine (CMM) and numerical controlled (NC) sandblast manufacturing equipment for large surface is presented in this paper. It uses transmission and position functions of NC machine and CMM's scan measuring function to make large...
Error analysis of free-form surfaces is a requirement to assure quality and to reduce manufacturing costs and rework. This paper proposes a new approach and algorithms for the error analysis of free-form surfaces. Given the measured surface as an input the approach first uses a statistical method to determine the number of test-points with suitable sample size for shape error analysis. Then, the system...
Automated inspection of parts is a requirement to assure quality and to reduce manufacturing costs and rework. This paper presents an inspection system of sheet metal parts with large and complicated curved surfaces used widely for manufacturing applications. For such sheet metal parts, which is characterized by a great volume, a big area, deforming easily and its loading and unloading can be difficultly,...
