Abstract: A new kind of measuring
schedule and set for geometric feature measurement in
cylindrical grinding process has been introduced in this paper.
Considering the characteristics of in-process measurement,
three-point measurement method for roundness and other form
indexes is improved and adapted in order to separate the error
of rotation and detect the measured profile features accurately
by mathematical means of geometric analyses and discrete Fourier
transform. Verification method and affecting factors of the
measurement are discussed also.
Key words:
