With this kind of software, there’s a wide range of quality. A Fair Warning about Post Processing Software! And that can lead to angry customers who take their business elsewhere.

That all translates to wasted time and money at your business too. Without it, or with poor software, you can end up with longer cycle times, damaged parts, ruined equipment, and injuries to employees. The final accuracy of your cut and optimal use of your CNC machine depends on your post processor software. See, not so hard to understand how it works now, is it? Why Do You Need Post Processor Software?
#POST PROCSSOR SOFTWARE#
So, that’s where post processor software comes in and translates this CL-file into specific data your CNC machine can use. However, these paths are not yet specific to your CNC machine. This “CL-file” only represents the paths your CNC machine will take when cutting your part. Whatever CAD or CAM system you use, it has a certain point where it produces generic output called a “CL-file.” A post processor is software that translates CAD or CAM data to specific commands your CNC cutting machine can understand. Your CNC cutting machine needs to know what commands you’re giving it. Here’s some introductory info to make sure you know: First, What is a Post Processor? You realize you know the term, but you’re not quite sure about much else.ĭon’t sweat it! We have you covered. Mid-point of arc in Y (incremental coordinates).ĭiameter of cylinder that axis is wrapped around.You’ve probably heard of “post processors.” But if you’re like most CNC machine operators, it’s kind of a foggy idea. Mid-point of arc in X (incremental coordinates). Mid-point of arc in Y (absolute coordinates). Mid-point of arc in X (absolute coordinates).

For an example, see the file: Roland_MDX-40_mm.ppĬurrent power setting for jet-based tools (e.g. Spindle speed for this machine is output as a range of integer numbers between 1 and 15 representing the actual speed in RPM of the spindle, (between 450 RPM in the quoted example). The moves in the X axis are to be wrapped around a cylinder of the specified diameter.

The moves in the Y axis are to be wrapped around a cylinder of the specified diameter. The control software uses a document interface that can directly accept the NC file output. Indicates that plunge moves to Plunge (Z2) height (that is set on the material setup form) are rapid movesĭIRECT_OUTPUT="Display Name|Manufacturers.Document"
#POST PROCSSOR DRIVER#
The machine tool manufacturer has supplied a driver (usually a printer driver) thatn can directly accept the NC file output (For example see Generic HPCL_Arcs.pp) The units that the file outputs (INCHES or MM) The file extension that the file will be given The name that will appear in the post processor list Vectric post processors are broken down into sections to aid clarity, try to write your post processors in a similar style to aid debugging. The Vectric post processor uses simple text based configuration files, to enable the user to tailor a configuration file, should they wish to do so. Machine controller manufacturers will often customize the file format required for programs to run on a particular machine in order to optimize the control to suit the individual characteristics of that machine.
#POST PROCSSOR HOW TO#
This document details how to create and edit the configuration files that customize the output from the program to suit a particular machine control.īelow are sections of a typical program that has been post processed into both G-Code and HPGL The post processor is the section of the program that converts the XYZ coordinates for the tool moves into a format that is suitable for a particular router or machine tool.
