Example of orientational toolholders

Requirement
The following example uses a toolholder, which is described fully by a rotation about the
Y axis. It is therefore sufficient to enter only one value to define the rotary axis (block N20).
Blocks N50 to N70 describe an end mill with radius 5 mm and length 20 mm.
Block N90 defines a rotation of 37 degrees about the Y axis.
Block N120 activates the tool radius compensation and all settings are made to describe the
compensation in the following blocks with a rotation of 37 degrees about the Y axis.
N10
N20 $TC_CARR8[1] = 1
N30
N40
N50 $TC_DP1[1,1] = 120
N60 $TC_DP3[1,1] = 20
N70 $TC_DP6[1,1] = 5
