The article describes an automated production of process documentation in an environment of PTC Creo 3.0. Process documentation is a simplified form of technological documentation, which is directly generated in the environment of comprehensive CAD-CAM-CAE system. Creation of process documentation is based on design of the templates that contain all the necessary information to ensure a smooth production process by production operators. Generating takes place on the inputs received from the proposal of NC machining program. The main advantage of the creation of process documentation is its fast processing, the possibility of additional editing, archiving, graphical representation of machining sequences and tools for generating at any moment during working time. The result of the creation is generated process documentation, which represents a complete supporting documentation. Generated process documentation with the created NC program provides required information for CNC machine operators to ensure the smooth process of machining parts.
