2.8.10.1

Example: Toolholder with orientation capability

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
N80
N90 ROT Y37
N100
N110 X0 Y0 Z0 F10000
N120 G42 CUT2DF TCOFR TCARR = 1 T1 D1 X10
N130 X40
N140 Y40
N150 X0
N160 Y0

Example of toolholder with orientation capability with rotary table

Use of the MOVT command
For use of the MOVT command it is assumed that the program is running on a 5axis machine,
on which the tool rotates about the Y axis in case of a rotation of the B axis:
N10 TRAORI()
N20 X0 X0 Z0 B45 F2000
N30 MOVT=-10
