Example 5:
Assumptions:
Spindles are toolholders at the same time:
MD20124 $MC_TOOL_MANAGEMENT_TOOLHOLDER = 0
In the event of a tool change tool offset data record D4 is selected automatically.
MD20270 $MC_CUTTING_EDGE_DEFAULT = 4

Refers to tool offset D1 of T="WZ2", S1 continues to turn
at previous speed.
; Corresponds to T8="WZ8"
; S3 = (200 m/min * 1,000) / (5.0 mm * 2 * 3.14) =
6369.43 rpm
Refers to tool offset D1 of T="WZ2".
; Corresponds to M3=6
Tool "WZ8" is in the master spindle, tool offset D4 of the
new tool becomes active.
; S3 = (50 m/min * 1,000) / (7.0 mm * 2 * 3.14) = 1137.40 rpm
Offset D4 on master spindle is active.
; Offset D1 of new tool "WZ8" active.
; S1 = (300 m/min * 1,000) / (9.0 mm * 2 * 3.14) =
5307.86 rpm
S3 = (50 m/min * 1,000) / (9.0 mm * 2 * 3.14) = 884.64 rpm
