Structures of SM_CNC.lib
dT1, dT2: LREAL
These variables contain the start and end positions of the parameter. Depending on the
Move_Type, this means:
dToolRadius: LREAL
Within this variable the information required for the path preprocessing is saved (see
SMC_ToolCorr
( 173)
). The entry has no relevance if corresponding path preprocessing
blocks (SMC_ToolCorr, SMC_RoundPath) are not passed through.
dVel, dVelEnd: LREAL
These two variables, which must always be assigned, contain information relating to the
velocity profile in this object. dVel describes the setpoint velocity to be achieved, dVelEnd
describes the velocity that must be reached at the end of the object (see SMC_Interpolator
( 185)
), both in path units/s.
dAccel, dDecel: LREAL
The maximum permissible acceleration and deceleration in path units/s2 are stored in
dAccel and dDecel. Both variables are pre-assigned a value of 100.
dLength: LREAL
This variable, which must always be assigned, contains the length of the object in path
units.
byIntern_Mark: BYTE
The start and end of path preprocessing actions are stored here as follows:
LIN Not relevant, as all information is already contained in Start_Pos and Dest_Pos.
CLW
ELLCLW
• T1: Start angle in mathematical sense (degrees): (0 = east, 90 = north, 180 = west,
360 = south)
• T2: Opening angle of the circle, arc length in degrees (e.g.: 90 = quarter circle,
180 = half circle)
CCLW
ELLCCLW
T1: Start angle in mathematical sense (degrees): (0 = east, 90 = north, 180 = west,
360 = south)
T2: Negative opening angle of the circle (e.g.: -90 = quarter circle, -180 = half circle)
SPLINE Start and end value of parameter t (see description of a spline). Default: 0 and 1.
INITPOS Not relevant
Bit 0 set Stop tool radius correction after this object
Bit 1 set Start tool radius correction to the left of this object
Bit 2 set Start tool radius correction to the right of this object
Bit 3 set Stop path rounding/smoothing after this object
Bit 4 set Start path smoothing at this object
Bit 4 set Start path rounding at this object
Bit 6 set Stop avoiding loops after this object
Bit 7 set Start avoiding loops at this object
