Class G53p1RotaryPositionSyntax

Namespace
Hi.NcParsers.LogicSyntaxs
Assembly
HiMech.dll

G53.1 — non-modal, one-shot rotary axis positioning. Positions the rotary axes (A/B/C) to align the physical tool axis with the active tilted work plane defined by G68.2. XYZ position is unchanged; only rotary axes move via rapid traverse.

Requires IsoG68p2TiltSyntax (or equivalent) to have written the tilt transform. Uses IMachineKinematics to solve for the target A/B/C via inverse kinematics.

Must be placed after IsoG68p2TiltSyntax (needs tilt data) and before ProgramXyzSyntax in the syntax chain. Writes A/B/C into MachineCoordinateState. Motion is handled by LinearMotionSyntax via modal G00/G01.

Examples

No-kinematics dep-guard early-return: standalone G53.1 with no IMachineKinematics dep in the list — the syntax detects the flag, finds no kinematics, and silently consumes the flag via ConsumeFlag. Empty Parsing is then removed by CleanupParsing(JsonObject), so the post-Build block is empty: #BeforeBuild:

{ "Parsing": { "Flags": ["G53.1"] } }

#AfterBuild:

{}

IK happy path — G53.1 with active G68.2 tilt on #Previous:, real XyzabcSolver (table-A / head-B 5-axis), and a TestDeps.AxisConfig(A=Rotary, B=Rotary) dep. The syntax reads the previous block's tilt Mat4d, solves OrientationToMcAbc(tiltMat.AxialNormal) for the rotary ABC, converts radians → degrees, writes MachineCoordinateState with both rotary axes (XYZ inherited from prevMc = Vec3d.Zero when no previous MC exists), and stamps ProgramXyz: #Previous:

Explicit ABC override — G53.1 A0 B45 on top of the same G68.2 tilt + kinematics + axis-config set up. The IK still solves, but the explicit A=0 and B=45 overrides what IK returned for those axes; C stays at the IK-solved value (C-axis is not present in the table-A/head-B layout, so the rotaryAxes loop only writes A and B): #Previous:

Remarks

When IMachineKinematics is not available (3-axis config), G53.1 is silently consumed with no positional effect. When G68.2 is not active, a validation error is reported.

Optional explicit A/B/C on the G53.1 line (post-processor hints) override the IK result. These are read from Parsing via ConsumeAxis(JsonObject, string, ISentenceCarrier, NcDiagnosticProgress) and consumed to prevent McAbcSyntax from double-processing.

Constructors

G53p1RotaryPositionSyntax()

Initializes a new instance with default settings.

public G53p1RotaryPositionSyntax()

G53p1RotaryPositionSyntax(XElement)

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

public G53p1RotaryPositionSyntax(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
