A post processor converts the cutting path generated by CAM into an NC program suitable for the configuration of the controller and machine tool.
Typically, company-specific NC machines and CAM systems have corresponding conversion libraries. Thus, a post processor is usually required for each control device or NC machine tool, but some post processor can register the specifications specific to a control device or NC machine tool in parameter form and switch to the NC data corresponding to each machine with a simple operation.
Post processors are used to convert the cutting paths generated by CAM into NC programs suitable for the configuration of the controller and machine tool. The main machine tools for which post processors are used are 3-axis to 5-axis machining, NC lathes, punch cut, wire cut, laser cut, and combined lathes.
Controller manufacturers include Yamazaki Mazak, Ohm, Okuma, and Fanuc, etc. CAM systems include AUTON, CATIA V4/V5, DELCAM, CIMATRON, Pro-E, I-DEAS, MasterCAM, SURFCAM, Unigraphics, VX, WX, and WM. Unigraphics, VX, WorkNC, etc.
3D-CAD data is becoming increasingly popular in the manufacturing field to facilitate product data linkage across departments and advance verification in the upstream process. However, in parts machining, multitasking machines are now in widespread use to accommodate diversified process intensification and production forms such as part shapes, and easy conversion to NC programs using 3D-CAM is required. Post processors are used to perform this conversion accurately.
Post processors perform post-processing using dedicated post-processing applications suitable for various CAM systems, reverse process the target NC data, and convert it to NC data for other models by utilizing past NC data assets.
The post processors supports input of any of various APT sources; it also supports input of CL data, which can be adapted to each machine by setting the specifications of the NC machine tool and controller.
Machining information such as machining time, machining start coordinates, machining end coordinates, and NC conversion results can be output. In general, the contents of post processors are not disclosed.
