A post processor for SolidWorks CAM is a crucial component in the CNC machining process. It is responsible for converting the toolpath data generated by SolidWorks CAM into a format that can be understood by a specific CNC machine.
What does a post processor do?
A post processor acts as a translator between the CAM software and the CNC machine. It takes the toolpath information, which includes details about the cutting tools, feeds, speeds, and other machining parameters, and converts it into a language that the CNC machine can understand. This language is often referred to as G-code.
Why is a post processor important?
A post processor plays a vital role in ensuring that the CNC machine executes the desired machining operations accurately and efficiently. Without an appropriate post processor, the generated toolpaths may not be compatible with the specific CNC machine’s requirements.
By using a suitable post processor, machinists can optimize their machining processes by taking advantage of the unique capabilities of their CNC machines. This includes features such as tool changes, coolant control, spindle speed adjustments, and more.
How does a post processor work?
The process of using a post processor begins with generating toolpaths in SolidWorks CAM. Once the toolpaths are defined, they are sent to the post processor along with information about the desired cutting parameters.
The post-processor analyzes this data and generates G-code instructions based on predefined rules and configurations specific to each CNC machine. These rules consider factors such as coordinate systems, tool change procedures, safety codes, probing routines, and any machine-specific features.
Customizing Post Processors
In some cases, standard post processors may not fully meet specific requirements or take advantage of advanced features offered by certain CNC machines. In such scenarios, users can customize or create their own post processors.
This customization can include modifying the G-code output, adding specific commands for the machine, or adjusting the formatting of the generated code. SolidWorks CAM provides options to customize post processors using a user-friendly interface or by editing the underlying code.
Post Processor Libraries
Post processor libraries are collections of pre-configured post processors that cover a wide variety of CNC machines. These libraries are often provided by SolidWorks or third-party vendors and can include post processors for popular machines such as Haas, Mazak, Fanuc, and more.
The availability of post processor libraries simplifies the process of finding and selecting an appropriate post processor. However, it is essential to choose a post processor that matches the specific CNC machine’s capabilities and requirements.
In conclusion
A post processor is an essential component in SolidWorks CAM that bridges the gap between CAM software and CNC machines. It ensures that toolpaths generated in SolidWorks CAM can be executed accurately on a specific CNC machine by translating them into machine-specific G-code instructions.
