Class TPostprocessor

Abstract blank postprocessor of CAM. When developing your postprocessor, you must inherit it from this class.

This class declares basic virtual methods that must be present in the postprocessor. However, most of the declared methods have empty implementation.

A significant number of methods are CAM's CLData command handlers, for example

  • OnGoto,
  • OnCircle,
  • OnSpindle,
  • OnLoadTool,
  • OnCoolant
  • etc.
If you want to implement any logic, or a set of actions that should be executed by any of these commands, then you must override the implementation of the corresponding method with your own inside your inherited class.

Namespace: DotnetPostprocessing.SDK
Assembly: DotnetPostprocessing.SDK.dll
Syntax

Constructors

TPostprocessor()

Constructor for the postprocessor. Initializes it's properties.

Declaration
public TPostprocessor()

Fields

Settings

An object containing a set of basic properties and settings for the processor, which are described in the separate Settings.xml file inside the folder of the postprocessor.

For example

  • Comments - any text comments to the postprocessor for customers.
  • CNCSystem - the CNC system the postprocessor was developed for.
  • MachineName - the name of a machine or robot for which the postprocessor is intended.
  • BreakArcs - whether the system should automatically split circular arcs into halves, quarters, or cuts.
  • BreakHelix - whether the system should automatically split helix into cuts.
  • etc.

A separate important part is the UserDefinedParameters section. Inside it, the postprocessor developer can add any properties of his choice, which the user will have to specify before starting the process of generating the output G-code files. This can be, for example,

  • the name of the output file,
  • program number,
  • textual description for the machine operator,
  • etc.
Later at a runtime you can ask the value of a property by it's name using syntax like following. 
nc.OutputFileName = Settings.Params.Str["OutFiles.NCFileName"];

This handler performs on PPFUN CLData command which can be used to transfer various kinds of data to the postprocessor. To determine the exact type of transfered data, use the cld[1] or cmd.SubCode (SubCode) parameter.

For example, CAM use this command to transfer the rich set of the technological operation parameters (PPFun StartTechInfo SubCode=58 and PPFun EndTechInfo SubCode=59). We recommend you to use OnStartTechOperation(ICLDTechOperation, ICLDPPFunCommand, CLDArray) and OnFinishTechOperation(ICLDTechOperation, ICLDPPFunCommand, CLDArray) handlers for this exact purpose instead of this one.

CAM also use this command to mark the beginning, end or call of subroutines which should be written to ouput files (PPFun StartSub SubCode=50, PPFun EndSub SubCode=51 and PPFun CallSub SubCode=52). We recommend you to use OnStartNCSub(ICLDSub, ICLDPPFunCommand, CLDArray), OnFinishNCSub(ICLDSub, ICLDPPFunCommand, CLDArray) and OnCallNCSub(ICLDSub, ICLDPPFunCommand, CLDArray) handlers for this exact purpose instead of this one.

The steps to use CLData breakpoints.

  • Go to CLData Viewer, open the CLData tab and select the command you want to break on. Click to the left field next to the line of this command.
  • Go back to Visual Studio Code and start debugging using "Run and debug" button or just press "F5".
  • When the translation process will reach the desired command it will be stopped inside the "StopOnCLData" method of your postprocessor.
  • After that you can start to press "F10" to continue debugging.
