Class PolarInterpolationSyntax

Namespace
Hi.NcParsers.LogicSyntaxs
Assembly
HiMech.dll

Maintains the modal Polar Coordinate Interpolation valve section (PolarInterpolationState) for Fanuc G12.1/G13.1.

On a G12.1 block: consumes the flag, reads the block's own X/C words as the anchor (InitRxcz; the X word is a diameter and is halved), converts the previous program position (program X/Z + machine C angle) onto the polar hypothetical plane via GetProgramPolarRxczByOrdinaryProgramXcz(Vec3d), and writes both the state section and the entry ProgramPolarRxcz position. Mirrors HardNc HardNcLine case 12_100.

On a G13.1 block: consumes the flag and stops carrying the state — the block itself is already Cartesian, matching HardNc case 13_100.

On other blocks: re-materializes the previous block's state section (single-step lookback carry, the PositioningSyntax pattern), and warns FanucPolar--IncompatibleGCode for G-codes outside the Fanuc polar-mode whitelist (mirrors HardNc IsGCodePolarModeCompatible).

Must be placed before McAbcSyntax so the downstream ProgramRxczSyntax can consume the hypothetical C word before it is interpreted as a rotary machine axis.

Examples

Bare G12.1 entry — anchor words absent so InitRxcz is zero; the entry position is the previous stored program position (program X/Z with the previous machine C angle) mapped onto the hypothetical plane: #Previous:

{ "ProgramXyz": { "X": 58, "Y": 0, "Z": 25 }, "MachineCoordinateState": { "X": 58, "Y": 0, "Z": 25, "C": 0 } }

#BeforeBuild:

{ "Parsing": { "Flags": ["G12.1"] } }

#AfterBuild:

{
  "PolarInterpolationState": { "Dir": "XC", "InitRxcz": { "X": 0, "Y": 0, "Z": 0 } },
  "ProgramPolarRxcz": { "X": 58, "Y": 0, "Z": 25 }
}

G12.1 X10 C0 — the block's own words anchor InitRxcz (X diameter 10 → radius 5) and the entry position is stored relative to that anchor: #Previous:

{ "ProgramXyz": { "X": 58, "Y": 0, "Z": 25 }, "MachineCoordinateState": { "X": 58, "Y": 0, "Z": 25, "C": 0 } }

#BeforeBuild:

{ "Parsing": { "X": 10, "C": 0, "Flags": ["G12.1"] } }

#AfterBuild:

{
  "PolarInterpolationState": { "Dir": "XC", "InitRxcz": { "X": 5, "Y": 0, "Z": 0 } },
  "ProgramPolarRxcz": { "X": 53, "Y": 0, "Z": 25 }
}

Carry — no G12.1/G13.1 edge on the block, previous block is in polar mode, so the state section is re-materialized; other parsing content is untouched (G01 is polar-compatible, no diagnostic): #Previous:

{ "PolarInterpolationState": { "Dir": "XC", "InitRxcz": { "X": 0, "Y": 0, "Z": 0 } } }

#BeforeBuild:

{ "Parsing": { "Flags": ["G01"] } }

#AfterBuild:

{
  "Parsing": { "Flags": ["G01"] },
  "PolarInterpolationState": { "Dir": "XC", "InitRxcz": { "X": 0, "Y": 0, "Z": 0 } }
}

G13.1 — the flag is consumed and the state is not carried; the block is already Cartesian: #Previous:

{ "PolarInterpolationState": { "Dir": "XC", "InitRxcz": { "X": 0, "Y": 0, "Z": 0 } } }

#BeforeBuild:

{ "Parsing": { "Flags": ["G13.1"] } }

#AfterBuild:

{}

G12.1 repeated while polar mode is already active — HardNc keeps the old anchor (the modal flag does not change), so the state is carried unchanged and the block's axis words are left for ProgramRxczSyntax to treat as plain polar motion: #Previous:

{ "PolarInterpolationState": { "Dir": "XC", "InitRxcz": { "X": 0, "Y": 0, "Z": 0 } } }

#BeforeBuild:

{ "Parsing": { "X": 20, "Flags": ["G12.1"] } }

#AfterBuild:

{
  "Parsing": { "X": 20 },
  "PolarInterpolationState": { "Dir": "XC", "InitRxcz": { "X": 0, "Y": 0, "Z": 0 } }
}

Constructors

PolarInterpolationSyntax()

Initializes a new instance with default settings.

public PolarInterpolationSyntax()

PolarInterpolationSyntax(XElement)

Initializes a new instance by deserializing from the given XML element.

public PolarInterpolationSyntax(XElement src)

Parameters

src XElement

Source XML element.

Fields

IncompatibleDiagId

Diagnostic id for G-codes that Fanuc disallows during polar coordinate interpolation (per the Fanuc manual whitelist).

Coverage note: the check sees only codes still present in Parsing.Flags when this syntax runs — codes consumed by earlier Logic syntaxes (G17/G18/G19 by PlaneSelectSyntax, G43/G44/G49 by ToolHeightOffsetSyntax) pass silently. The polar plane normal is hard-coded to the XC pair, so those codes cannot corrupt the trajectory; the gap is diagnostic-only. 

public const string IncompatibleDiagId = "FanucPolar--IncompatibleGCode"

Field Value

string

Properties

Name

Syntax kind name (typically the concrete type name).

public string Name { get; }

Property Value

string

XName

XML element name used to register this syntax with XFactory.

public static string XName { get; }

Property Value

string

Methods

Build(LazyLinkedListNode<SyntaxPiece>, List<INcDependency>, NcDiagnosticProgress)

Build syntax arrangement into the syntaxPieceNode in-place.

public void Build(LazyLinkedListNode<SyntaxPiece> syntaxPieceNode, List<INcDependency> ncDependencyList, NcDiagnosticProgress ncDiagnosticProgress)

Parameters

syntaxPieceNode LazyLinkedListNode<SyntaxPiece>
ncDependencyList List<INcDependency>
ncDiagnosticProgress NcDiagnosticProgress

MakeXmlSource(string, string, bool)

Creates an XML representation of the object. This method may also generate additional resources such as related files.

public XElement MakeXmlSource(string baseDirectory, string relFile, bool exhibitionOnly)

Parameters

baseDirectory string

The base directory for resolving relative paths

relFile string

The relative file path for the XML source

exhibitionOnly bool

if true, the extended file creation is suppressed.

Returns

XElement

An XML element representing the object's state

Remarks

For the demand of easy moving source folder (especially project folder) without configuration file path corruption, the relative file path is applied. The baseDirectory is typically the folder at the nearest configuration file folder. Since the folder can be moving with the configuration file.

Reg(XFactory)

Registers this type's deserializer with the given XFactory (or Default when factory is null). Idempotent.

public static void Reg(XFactory factory = null)

Parameters

factory XFactory
