Function and notes:
In the as-delivered state of the measuring cycles the default setting of the of the arrays is 0.
The radii and peripheral speeds must be entered in ascending order.
These arrays are only accessed in automatic mode when _MT_COMP = 2. When tool
measuring with a rotating spindle, the tool radius of the tool being measured is used to
calculate a compensation value from these tables. The value for the next lowest table
peripheral speed and the next lowest table radius are always the values used. In radius
measurement the corresponding compensation value in array _MT_EC_R[n,m] is subtracted
from the measured tool radius. In length measurement the corresponding compensation
value in array _MT_EC_L [n,m] is subtracted from the measured tool length.
