Class PeckDrillingCycleSyntax

Namespace
Hi.NcParsers.LogicSyntaxs
Assembly
HiMech.dll

G83 peck drilling cycle. Supports modal repetition. Drills in increments of depth Q, fully retracting to R between strokes.

Cycle sequence (per stroke):

  1. Rapid to init position (target XY, previous Z)
  2. Rapid from init to R-point
  3. For each stroke: rapid to clearance above previous depth, feed Q deeper, rapid back to R
  4. If remainder exists: feed to bottom Z, rapid to R
  5. Rapid from R/bottom to final (G98 → init Z, G99 → R)

Retraction distance is read from ICannedCycleConfig (Fanuc #4002 / Syntec Pr4002, or FallbackConfig fallback).

Reads absolute coordinates from the cycle section, which is resolved by CannedCycleResolveSyntax (modal repetition, G91 conversion, missing-axis fallback) before this syntax runs. Must be placed after CannedCycleResolveSyntax and before IncrementalResolveSyntax in the syntax chain.

Examples

Both cases below pre-populate CannedCycle as CannedCycleResolveSyntax would have written it. There is no #Previous:, so GetLastProgramXyz returns Vec3d.Zero → initZ = 0. A FallbackConfig dep with the default PeckRetractionDistance_mm = 5 is injected via BuildAndDump(..., deps:). Cycle parameters are chosen so totalFeedLength = R − bottomZ = 10 and Q = 10 → exactly one stroke, no remainder; the items list stays minimal.

G83 G98 — rapid to init (z=0), rapid to R=2, feed to bottom Z=-8 at F=600 mm/min → 10 mm/s, rapid back to R=2, then a final rapid to init Z=0 (G98). Five items:

#BeforeBuild:

  }
}

      { "ProgramXyz": { "X": 50, "Y": 30, "Z": 2 },  "MotionEvent": { "Form": "McLinear", "IsRapid": true } },
      { "ProgramXyz": { "X": 50, "Y": 30, "Z": 0 },  "MotionEvent": { "Form": "McLinear", "IsRapid": true } }
    ]
  },
  "ProgramXyz": { "X": 50, "Y": 30, "Z": 0 }
}
G83 G99 — same cycle but the return mode is R-point. Since the retract-to-R rapid already lands at z = R, the finalZ != rPoint guard skips the extra final-rapid item. Four items, and the block's ProgramXyz lookback anchor lands at R-point: #BeforeBuild: 
{
  "Parsing": { "G83": { "X": 50, "Y": 30, "Z": -8, "R": 2, "Q": 10, "F": 600 } },
  "CannedCycle": {
    "Term": "G83", "ReturnMode": "G99",
    "Params": { "X": 50, "Y": 30, "Z": -8, "R": 2, "Q": 10 }
  }
}
#AfterBuild:

  "CannedCycle": {
    "Term": "G83", "ReturnMode": "G99",
    "Params": { "X": 50, "Y": 30, "Z": -8, "R": 2, "Q": 10 }
  },

      { "ProgramXyz": { "X": 50, "Y": 30, "Z": 2 },  "MotionEvent": { "Form": "McLinear", "IsRapid": true } },
      { "ProgramXyz": { "X": 50, "Y": 30, "Z": -8 }, "MotionEvent": { "Form": "McLinear", "Feedrate_mmds": 10 } },
      { "ProgramXyz": { "X": 50, "Y": 30, "Z": 2 },  "MotionEvent": { "Form": "McLinear", "IsRapid": true } }
    ]
  },
  "ProgramXyz": { "X": 50, "Y": 30, "Z": 2 }
}

Remarks

G73 (high-speed peck) retracts only a small distance instead of fully back to R — see HighSpeedPeckCycleSyntax.

Constructors

PeckDrillingCycleSyntax()

Initializes a new instance with default settings.

public PeckDrillingCycleSyntax()

PeckDrillingCycleSyntax(XElement)

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

public PeckDrillingCycleSyntax(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
