COORDINATE MEASUREMENT OF 3D LINE ON FREEFORM SURFACE

Abstract

3D line is defined as a line in 3D space in general position with respect to the coordinate system. However, it is impossible to consider any line in dimensional metrology without respect of underlying geometry. The paper deals with 3D line located on freeform surface and introduces a new approach to process data measured along this line by tactile coordinate measuring. Three different methods of interpretation of measured data and form error determination are described here.
