RAPID - Rapid feedrate

Command caption

How the command appears in the CLData command list:

RAPID N n

RAPID activates rapid travel mode (G-code G00). All further travels are done in rapid mode until feedrate modification command FEDRAT is received.

Access from sppx

Handler: program Rapid

Parameter CLD array CLD name Description
n CLD[1] CLD.N Rapid feedrate value

Example (from the Fanuc (30i)_Mill postprocessor):

program Rapid
  if IsRotaryInterpolation>0 then begin
    INTERP_ = 1
    Feed_ = 5000
    GFeed = 94
  end else begin
    if INTERP_ > 0 then INTERP_ = 0    ! G0
  end
  RapFr=cld[1]
end

Access from .NET

Handlers:

public override void OnMoveVelocity(ICLDMoveVelocityCommand cmd, CLDArray cld)   // shared velocity handler (FEDRAT and RAPID)
public override void OnRapid(ICLDRapidCommand cmd, CLDArray cld)   // rapid feed

Inheritance: ICLDRapidCommand : ICLDMoveVelocityCommand : ICLDCommand.

Read the parameters from the strongly-typed cmd object (recommended); the raw cld[i] array (same indices as in sppx) and the named cmd["..."] helpers are available too. The table lists the command's members, including those inherited from its base interfaces; the common ICLDCommand members (navigation, CLD, CLDFile, TechOperation, ...) are described in the CLData access model.

Member Type Description
cmd.IsRapid bool Contains "true" if the command is a RAPID command, otherwise it is "false".
cmd.FeedKind CLDFeedKind The kind of a feed (working, rapid, engage, return, finish etc.).
Possible values:
Working (0) - The feed kind for base working movements.
Rapid (1) - The feed kind of rapid movements.
First (2) - The feed kind for the working movements on a first (roughing) pass.
Engage (4) - The feed kind for the movements entering to the first machining (cutting) point.
Retract (8) - The feed kind for the movements leaving the last machining (cutting) point.
Plunge (16) - The feed kind for the movements that plunge vertically into the machining area.
Finish (32) - The feed kind for the working movements on a last (finishing) pass.
Next (64) - The feed kind for the short link movements.
Return (128) - The feed kind for the movements which take the tool away from the machining site.
Approach (256) - The feed kind for the movements which bring the tool closer to the machining site.
Rapid5D (512) - The feed kind value reserved for an internal use.
TransitionOnSafe (1024) - The feed kind for the movements performed in a safe area.
ApproachFromSafe (2048) - The feed kind for the movements from the safe area to the machining side.
ReturnToSafe (4096) - The feed kind for the movements from the machining side to the safe area.
LongNext (8192) - The feed kind for the long link movements.
ThreadPitch (16384) - The feed kind for the threading movements.
Overload (1073741824) - The feed kind value reserved for an internal use.
cmd.FeedCode int Numerical representation of the "FeedKind" flag, that defines the kind of a feed (working, rapid, engage, return, finish etc.). For a wire EDM case it contains the numerical code of a row in a machining conditions table.
cmd.FeedUnits CLDFeedUnits Units of the feed (mm/min, mm/rev etc.)
Possible values:
MPM (0) - Current linear units (mm or inch) per minute.
MPR (1) - Current linear units (mm or inch) per revolution.
ConditionCode (2) - Numerical code of a row in a machining conditions table (for a wire EDM).
cmd.FeedValue double The value of the feed.

Example - OnMoveVelocity (from the Fanuc (30i)_Mill_DN postprocessor):

public override void OnMoveVelocity(ICLDMoveVelocityCommand cmd, CLDArray cld)
{
    if (cmd.IsRapid) {
        nc.GInterp.v = 0;
    } else {
        if (nc.GInterp == 0)
            nc.GInterp.v = 1;
        nc.F.v = cmd.FeedValue;
        if (cmd.FeedUnits==CLDFeedUnits.MPR) 
            nc.GFeed.v = 95;
        else 
            nc.GFeed.v = 94;
        if (IsFirstFeed) 
        {
            nc.F.Show();
            nc.GFeed.Show();
            IsFirstFeed = false;
        } 
    }
}
