MD20184 $MC_TOCARR_BASE_FRAME_NUMBER
is described.
With kinematics systems of the types P and M, TCARR will enter the table offset of the orientational toolholder
(zero offset resulting from the rotation of the table) as a translation into the system frame. PAROT converts the
system frame such, that a part­oriented WCS results.
The system frames are stored in the SRAM and, therefore, remain stored after Reset. The system frames also
remain active in the case of a mode change.
For the display, the G codes PAROT and TOROT,TOFRAME are each assigned to a separate G code group.
PAROTOF
PAROTOF is the switch off command for PAROT. This command deletes the rotations in the system frame for
PAROT. In so doing, the rotations in the current $P_PARTFRAME and in the data management frame
$P_PARTFR are deleted. The position of the coordinate system is then recreated according to TCARR. PAROTOF
is in the same G code group as PAROT and appears, therefore, in the G code display.
TOROT and TOFRAME
The system frame for TOROT and TOFRAME is configured with bit 3 in machine data:
MD28082 $MC_MM_SYSTEM_FRAME_MASK
.
This system frame is located before the programmable frame in the frame chain.
The SZS coordinate system is located before the programmable frame.
TOROTOF
TOROTOF is the switch off command for TOROT and TOFRAME. This command deletes the system frame for
TOROT and TOFRAME. The current $P_TOOLFRAME and the data management frame $P_TOOLFR are also
deleted. TOROTOF is in the same G code group as TOROT and TOFRAME and appears, therefore, in the G code
display.
Example
Example of using an orientational toolholder with deactivated kinematics:
N10 $TC_DP1[1,1]= 120
N20 $TC_DP3[1,1]=13
; Definition of toolholder 1:
N30 $TC_CARR1[1] = 0
N40 $TC_CARR2[1] = 0
N50 $TC_CARR3[1] = 0
N60 $TC_CARR4[1] = 0
N70 $TC_CARR5[1] = 0.
N80 $TC_CARR6[1] = -15.
N90 $TC_CARR7[1] = 1
N100 $TC_CARR8[1] = 0
