Step 4: The code is exported to the machine and the manufacturing process begins.ĬAD/CAM post processing is a delicate process, and requires skill. The output produced by the post processor is usable without any further modifications. The post processor converts the toolpath fed to it into language that the machine understands. Step 3: This is where the CAD/CAM post processor comes into the picture. Step 2: The CAM System is then fed information about the machining operations by the CNC programmer and it creates the path that the tools will take. Step 1: The 3D CAD model is imported into the CAM System. Here are the steps that leads up to the post processing stage: The Process Leading up to the CAD/CAM Post Process LevelĬAD/CAM post processing makes it possible for the manufacturing process to start without an error. The point of a good post processor is that the CAM code reaches the machine in a format that the machine is able to understand. A company can have the most cutting edge designs and the best programming systems, but it’s the post processor that ensures that the code that reaches the machine is perfect. The post processor is actually the most important part of the system. Initially CAD and CAM were used individually but eventually engineers started using them together to create a process that makes it easy for CNC operators to program machinery.ĬAD/CAM post processing is a result of this combination and is the last link between the CAD model and the actual machine. It essentially simplifies the designing process.ĬAM or Computer Aided Manufacturing simplifies the programming process of creating the machines. CAD, as the name suggests, allows engineers to design complex machinery without spending time on long calculations. Mid-point of arc in Y (incremental coordinates).ĭiameter of cylinder that axis is wrapped around.To begin with, let’s talk about what CAD or Computer Aided Design does. Mid-point of arc in X (incremental coordinates).
Mid-point of arc in Y (absolute coordinates). Mid-point of arc in X (absolute coordinates). Text from Note field in ToolDB for current toolįilename (Produced by “Save Toolpath(s)”).Ĭurrent coordinate of tool position in X axis.Ĭurrent coordinate of tool position in Y axis.Ĭurrent coordinate of tool position in Z axis.Ĭurrent coordinate of tool position in A axis.Īrc centre in X Axis (relative to last X,Y position).Īrc centre in Y Axis (relative to last X,Y position).Īrc centre in X Axis (absolute coordinates).Īrc centre in Y Axis (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"

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.

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.
