10.91 4 Measuring Cycles for Turning Machines
4.1 L972/L982 Tool measurement
Tool types 28, 37 and 38, R23=x1x2
With tool type 28, L1 and R
are determined.
With tool types 37 and 38, L1, L2 and R
are determined.
The first measuring point is measured in the abscissa and ordinate. The tool is then turned
through 180 degrees and the same cutting edge is measured again in the two axial directions.
The average values of the two measurements provide the L1 and L2 dimensions. The cutter
radius is determined from half the dimensional difference between measuring point 1 and
measuring point 2 in the ordinate.
