Abstract
This paper presents a method for applying the ISO 10303-238 (AP-238) standard in robotic machining operations by using two industrial robots. The method encompasses programming, simulation and machining by industrial robots. Application and validation of robotized machining is performed using two industrial robots, and the following tools are used: (a) a commercial CAD/CAM software with a plug-in to generate STEP-NC files (AP-238); (b) simulation with a STEP-NC-compliant software using two virtual robot models, as well as the generation of G-code files through postprocessors; and (c) two industrial robots (ASEA IRB6-S2 and LOLA 50) using the LinuxCNC controller adapted to STEP-NC. Initially, a 3D part is designed using any CAD system, and it is sent through the Internet to a CAM specialist who uses a commercial software to generate a process plan to manufacture the part. Operators of the robots download the part and its process plan information in the STEP-NC format, simulate its machining through the working steps and then perform machining using the robots.
