SPINDL - Spindle

Command caption

How the command appears in the CLData command list:

SPINDL ON(71)|OFF(72)|ORIENT(246), NO n, K k, MODE RPM(0)|RANGE(1)|CSS(2) {, SPEED c}

SPINDL command passes spindle control parameters. SPINDL command is used to define spindle rotation frequency or range of frequencies, surface speed, etc.

Access from sppx

Handler: program Spindl

The cld array is read by index or by name - in sppx by the typed short name (e.g. cld.X), in .NET by the same name as a string key (e.g. cld["X"]).

Parameter CLD array CLD name Description
ON(71)
OFF(72)
ORIENT(246)		 CLD[1] CLD.OnOff Command type: ON(71) – spindle rotation on, OFF(72) – spindle rotation off, ORIENT(246) – oriented spindle stop.
n CLD[2] CLD.NO Rotation frequency, spindle rotation angle or maximum spindle rotation frequency in CSS mode.
k CLD[3] CLD.K Range of rotation frequencies.
RPM(0)
RANGE(1)
CSS(2)		 CLD[4] CLD.Mode Mode of the rotation frequency definition: RPM(0) – revolutions per minute, RANGE(1) – range of spindle rotation frequencies, CSS(2) – constant surface speed mode.
c CLD[5] CLD.CSS Constant surface speed value for the CSS mode.

To create ISO postprocessor using masks use ISO.M values which correspond to SPINDL parameters.

CLD parameter ISO value
CLD[1] = 71 ISO.M = 3
CLD[1] = 72 ISO.M = 5

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

program Spindl
  OutBlock
  case cld[1] of
    71: begin ! On
      if cld[4]=2 then begin ! CSS
        GSpindl = 96
        S = abs(cld[5])
        OutBlock
        if cld[5] > 0 then SpDir = 3
                      else SpDir = 4    ! M3/M4  CW/CCW
        SpRPM = abs(cld[2])
      end else begin ! RPM
        if cld[2] > 0 then Msp = 3
                      else Msp = 4    ! M3/M4  CW/CCW
        if ((SpDir=3) or (SpDir=4)) and (SpDir<>Msp) then ! Spindle reverse
          Output "M5"
        GSpindl = 97
        S = abs(cld[2]); S@=SpRPM
        Msp@ = SpDir
        SpDir = Msp
        SpRPM = abs(cld[2])
        OutBlock
      end
    end
    72: begin ! Off
      Msp = 5
      S=0; S@=S
      SpRPM = 0
      SpDir = 5    ! M3/M4/M5
      OutBlock  ! Msp = 5;; OutBlock; Msp=1; OutBlock
    end
    246: begin  ! M19 ORIENT
      OutBlock
      M = 19; M@ = MaxReal
      OutBlock
    end
  end
end

Access by parameter name (helpers)

Parameters available through the cmd operator (the same in sppx and .NET):

Name Helper Description
Action cmd.Int["Action"] Command kind (0 - on, 1 - off, 2 - orient).
RotationDirection cmd.Int["RotationDirection"] Rotation direction.
SpeedMode cmd.Int["SpeedMode"] 0 - RPM, 1 - RANGE, 2 - CSS.
Value cmd.Flt["Value"] Rotation frequency / orientation angle / max rpm.
CSSValue cmd.Flt["CSSValue"] Constant surface speed value.
RangeValue cmd.Int["RangeValue"] Gearbox range.
SpindleID cmd.Str["SpindleID"] Spindle identifier.

Access from .NET

Handler:

public override void OnSpindle(ICLDSpindleCommand cmd, CLDArray cld)

Inheritance: ICLDSpindleCommand : 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.

Property Type Description
cmd.SpindleID string Textual identifier of the spindle for which this command sets parameters.
cmd.Action CLDSpindleAction The action for the spindle (On, Off or Orient).
cmd.IsOn
cmd.IsOff
cmd.IsOrient		 bool True if it is a switch-ON / switch-OFF / angular-orientation command.
cmd.SpeedMode CLDSpindleSpeedMode The spindle rotation mode (RPM or CSS).
cmd.IsRPM
cmd.IsCSS		 bool True if the mode is RPM (rev/min, G97) / CSS (constant surface speed, G96).
cmd.RotationDir CLDRotationDir Rotation direction for the spindle (CW or CCW).
cmd.IsClockwiseDir bool True if the rotation direction is CW (clockwise).
cmd.RPMValue double Revolutions per minute (maximal if the CSS mode is active).
cmd.CSSValue double The value of a linear (surface) speed for the spindle.
cmd.GearRange int Spindle's gearbox range.

Example (from the Sinumerik 840D mill postprocessor):

public override void OnSpindle(ICLDSpindleCommand cmd, CLDArray cld)
{
    if (cmd.IsOn)
    {
        switch (cmd.SpeedMode)
        {
            case CLDSpindleSpeedMode.RPM:
                nc.S.Show(cld[2]);
                nc.Msp.Show(cmd.IsClockwiseDir ? 3 : 4);
                break;
            case CLDSpindleSpeedMode.CSS:
                throw new Exception("CSS mode not realized");
        }
    }
    else if (cmd.IsOff)
        nc.Msp.Show(5);
}
