Class RotaryAxisUtil

Namespace
Hi.NcParsers.LogicSyntaxs
Assembly
HiMech.dll

Shared utilities for rotary axis (A/B/C) resolution. Used by G53p1RotaryPositionSyntax, McAbcSyntax, IsoG68p2TiltSyntax, IncrementalResolveSyntax and other syntaxes that read or write rotary axis values.

Methods

ConsumeAxis(JsonObject, string, ISentenceCarrier, NcDiagnosticProgress)

Consumes an optional axis value (degrees) from Parsing. Post-processor hints (e.g., A/B/C on G68.2 or G53.1 lines) are parsed by FloatTagSetupSyntax into Parsing as doubles. Returns the value and removes the key, or null if not present.

A non-numeric value (e.g. "#124" left by the parser stage) raises VariableExpression--Unevaluated via GetParsedDouble(JsonObject, string, ISentenceCarrier, NcDiagnosticProgress) instead of silently dropping the post-processor hint. The key is consumed regardless so downstream syntaxes do not re-process it. 

public static double? ConsumeAxis(JsonObject parsing, string axisName, ISentenceCarrier sentenceCarrier, NcDiagnosticProgress diag)

Parameters

parsing JsonObject
axisName string
sentenceCarrier ISentenceCarrier
diag NcDiagnosticProgress

Returns

double?

FindPreviousMcAxisDeg(LazyLinkedListNode<SyntaxPiece>, string)

Walks backward through previous SyntaxPiece nodes to find the most recent MachineCoordinateState that carries a numeric value for the given axis — the axis's modal angle in degrees as the machine-state section stores it (after the McAbcCyclicPathSyntax wrap of that block), the anchor an incremental rotary word adds onto. Returns null when no predecessor carries the axis.

Per-axis (rather than whole-section) because intermediate blocks — e.g. CircularMotionSyntax blocks whose MC was written by SetVec3d(JsonObject, string, Vec3d) with XYZ only — can lack rotary fields; whole-section lookback would stop at such a block and mistakenly conclude the rotary value is unknown. Silent on a non-numeric value (the throwing machine-state reader — a non-numeric MC is a HiAPIs codegen bug, not a program error). 

public static double? FindPreviousMcAxisDeg(LazyLinkedListNode<SyntaxPiece> node, string axis)

Parameters

node LazyLinkedListNode<SyntaxPiece>
axis string

Returns

double?

GetRotaryAxes(IMachineAxisConfig)

Gets the rotary axis names from the given IMachineAxisConfig. Returns an empty array if no rotary axes exist.

public static string[] GetRotaryAxes(IMachineAxisConfig axisConfig)

Parameters

axisConfig IMachineAxisConfig

Returns

string[]
