Class IsoG68p2TiltSyntax

Namespace
Hi.NcParsers.LogicSyntaxs
Assembly
HiMech.dll

ISO/Fanuc: resolves G68.2 (tilted work plane) and G69 (cancel). Computes a tilt Mat4d from I/J/K euler angles (Fanuc ZXZ convention) and composes it into ProgramToMcTransform.

Managed commands: G68.2, G69 (idempotent with IsoG68RotationSyntax). Siemens equivalent: CYCLE800 (separate syntax). Heidenhain equivalent: PLANE SPATIAL (separate syntax).

Examples

G69 cancel via TryHandleG69(JsonObject, JsonObject) — the kinematics-free short-circuit path that writes the identity tilt.

Standalone G69 — the flag is consumed, TiltTransform is written with Term: "G69", and an identity Mat4d entry is added to ProgramToMcTransform so any previously composed tilt rotation is reset:

#BeforeBuild: 
{ "Parsing": { "Flags": ["G69"] } }
#AfterBuild: 
{
  "TiltTransform": { "Term": "G69" },
  "ProgramToMcTransform": [
    {
      "Source": "TiltTransform",
      "Kind": "Static",
      "Mat4d": [1,0,0,0, 0,1,0,0, 0,0,1,0, 0,0,0,1]
    }
  ]
}
G68.2 with IJK = (0, 30, 0) and no kinematics dep — exercises the pure ZXZ Fanuc euler math (Rz(K=0) * Rx(J=30°) * Rz(I=0) * Translate(0) = Rx(30°)) without any IK refinement. The TiltTransform section retains the G68.2 ctor params for debug; the chain entry's Mat4d is the rotation matrix: #BeforeBuild: 
{ "Parsing": { "G68.2": { "X": 0, "Y": 0, "Z": 0, "I": 0, "J": 30, "K": 0 } } }
#AfterBuild: 
{
  "TiltTransform": { "Term": "G68.2", "X": 0, "Y": 0, "Z": 0, "I": 0, "J": 30, "K": 0 },
  "ProgramToMcTransform": [
    {
      "Source": "TiltTransform",
      "Kind": "Static",
      "Mat4d": [
        1, 0, 0, 0,
        0, 0.8660254037844387, 0.49999999999999994, 0,
        0, -0.49999999999999994, 0.8660254037844387, 0,
        0, 0, 0, 1
      ]
    }
  ]
}
Same G68.2 IJK with a real XyzabcSolver (table-A / head-B 5-axis layout) — hasPostAbc is false but the kinematics solves OrientationToMcAbc(tiltByIjk) successfully, so the refinement path ijkAbcOrientation * orientationDelta * Translate(origin) runs. The resulting Mat4d preserves the IJK orientation but aligns it with the kinematic ABC solution: #BeforeBuild: 
{ "Parsing": { "G68.2": { "X": 0, "Y": 0, "Z": 0, "I": 0, "J": 30, "K": 0 } } }
#AfterBuild: 
{
  "TiltTransform": { "Term": "G68.2", "X": 0, "Y": 0, "Z": 0, "I": 0, "J": 30, "K": 0 },
  "ProgramToMcTransform": [
    {
      "Source": "TiltTransform",
      "Kind": "Static",
      "Mat4d": [
        1, 0, 0, 0,
        0, 0.8660254037844388, 0.5, 0,
        0, -0.5, 0.8660254037844388, 0,
        0, 0, 0, 1
      ]
    }
  ]
}
G68.2 IJK with explicit post-processor rotary hints A=0, B=30 — hasPostAbc is true, kinematics first solves tiltByIjk → ijkMcAbc, then overrides A/B with the explicit values to form postMcAbc; the final Mat4d combines postAbcOrient * orientationDeltaIjkToPost * Translate(origin). The TiltTransform section gains the consumed A and B entries: #BeforeBuild: 
{
  "Parsing": {
    "G68.2": { "X": 0, "Y": 0, "Z": 0, "I": 0, "J": 30, "K": 0 },
    "A": 0,
    "B": 30
  }
}
#AfterBuild: 
{
  "TiltTransform": {
    "Term": "G68.2",
    "X": 0, "Y": 0, "Z": 0,
    "I": 0, "J": 30, "K": 0,
    "A": 0, "B": 30
  },
  "ProgramToMcTransform": [
    {
      "Source": "TiltTransform",
      "Kind": "Static",
      "Mat4d": [
        0.8660254037844387, 0.0002477343364339079, -0.4999999386276948, 0,
        0, 0.9999998772553897, 0.0004954686728678159, 0,
        0.49999999999999994, -0.00042908845748289027, 0.8660252974844881, 0,
        0, 0, 0, 1
      ]
    }
  ]
}

Remarks

G68.2 optionally uses IMachineKinematics dependency for IK refinement. The ZXZ euler convention is Fanuc-specific: Rz(K) * Rx(J) * Rz(I) * Translate(origin).

Optional A/B/C parameters are post-processor rotary axis hints. When present and IMachineKinematics is available, the tilt is computed as: kinematicRotation(postAbc) * orientationDelta * Translate(origin) where orientationDelta = kinematicRotation(ijkAbc).Inverse * ijkRotation preserves the exact IJK orientation while aligning with the post-processor's solution.

Constructors

Initializes a new instance with default settings.

public IsoG68p2TiltSyntax()

IsoG68p2TiltSyntax(XElement)

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

public IsoG68p2TiltSyntax(XElement src)

Parameters

src XElement

Source XML element.

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
