Post Processing

Back      Next


The cutter location data (CL Data) produced by Pro/NC is meaningless to the machine controller. To transform the CL Data to useful controller acceptable instructions we need to post process it to machine control data (MCD) for a particular machine controller.



The topics covered are as follows.

  • What is post processing
  • Introduction to Option File Generator
  • Introduction to GPOST
  • Defining a new option file
  • Configuring Pro/NC to select the option file automatically
  • Modifying the option file settings to get the desired output
  • Inserting program number at the beginning
  • Inserting safety codes at the start of program.
  • Inserting a blank before each address
  • Changing the output order of addresses
  • Changing the default format of addresses
  • Changing the default behavior of radius output from IJK to R
    Inserting M30 at the end of MCD data
  • Modify the option file to get the output for following drilling cycles
       1: Drilling
       2: Peck Drilling
       3: High Speed Peck Drilling
  • Set the maximum federate to be output to tape file.
  • Set the maximum spindle RPM to be output to tape file
  • Set the option file to output operator messages to tape file
  • Set the option file to output tool length compensation code G43
  • Change the extension of tape file from .tap to .txt
  • Set the maximum value of radius to be output to tape file
  • Set the sequence number to be output with any specified increment

"We purchased both of the tutorials about a month ago, and I have to say I was skeptical because they were considerably less expensive compared to the other available tutorials that I found.  We had one of our CNC programmers and our lead mold designer evaluate them before we used these to train two new employees.  Both engineers had very good things to say about the tutorials.  Each said they learned or remembered things they hadn't used in a while and that the time they spent going through these was well spent.  I have to admit I can't wait for this company to produce some more generic tutorials on modeling, assembly, surfacing, etc.  In my opinion these tutorials represent a good value.  I hope they're able to continue to produce good material and keep their prices in check."
