Detailed Description
2.11 Tool lengths L1, L2, L3 assignment: LENTOAX
Syntax:
Value/parameter:
Status
_AXIND[3]
_MATRIX[3][3]
_COORD
2-150
Status = LENTOAX(_AXIND, _MATRIX, _COORD)
The first two parameters must always be programmed; the last parameter can be omitted.
INT
0: Function OK, information in _AXIND sufficient for description
(all tool length components are parallel to the geometry axes).
1: Function is OK, however, the content of _MATRIX must be evaluated for a correct
description (the tool length components are not parallel to the geometry axes).
-1: Invalid string in parameter _COORD.
-2: No tool active.
INT
Indices 0 to 2 are assigned to the abscissa (0), ordinate (1) and applicate (2)
(e.g., _AXIND[0] contains the number of the tool length components, which are effective in the
direction of the abscissa).
The content has the following meaning:
0: Assignment exists (axis does not exist)
1 to 3: Number of the length effective in the corresponding coordinate axis.
or The sign is negative if the tool length component is pointing in the negative
-1 to -3: coordinate direction.
REAL
Matrix, which represents the vector of the tool lengths (L1=1, L2=1, L3=1) to the vector of the
coordinate axes (abscissa, ordinate, applicate), i.e., the tool length components are assigned to
the columns in the order L1, L2, L3 and the axes are assigned to the lines in the order abscissa,
ordinate, applicate.
All elements are always valid in the matrix, even if the geometry axis belonging to the coordinate
axis is not available, i.e., if the corresponding entry in _AXIND is 0.
STRING
Specifies the coordinate system used for the assignment.
MCS or M: The tool length is represented in the machine coordinate system.
BCS or B: The tool length is represented in the basic coordinate system.
WCS or W: The tool length is represented in the workpiece coordinate system
(default).
KCS or K: The tool length is represented in the tool coordinate system of the
kinematic transformation.
TCS or T: The tool length is represented in the tool coordinate system.
The notation of the characters in the string (upper or lower case) is arbitrary.
