Abstracts: In accordance with the difficult problems of grinding non-axisymmetric
aspheric surfaces with 5-axis CNC machining and mould grinding, a new
parallel grinding method is put forward. To reduce the profile error of
workpiece in parallel grinding, the new truing technology of tilting
cup-truer, off-axis compensation in main axis and cross axis, and
compensation of wheel wear are used in the machining program design.
With grinding experiment and analyzing measured data, it is obvious that
new compensating method can meet the need of parallel grinding non-axisymmetric
aspheric surfaces.
Key words: Non-axisymmetric aspheric surface Parallel grinding
