Opis:
Postęp w dziedzinie oprogramowania CAM (Computer Aided Manufacturing) i rosnące możliwości obrabiarek CNC (Computer Numeric Control) powodują, że wymagania w stosunku do postprocesorów są bardzo wysokie, jeśli chodzi o ich niezawodność, możliwości, spełnianie oczekiwań użytkownika. Praca poświęcona jest wybranym problemom przetwarzania końcowego (postprocesingu), wynikającym z praktycznych zastosowań; uzyskanych w trakcie wdrożeń postprocesorów na różnych typach obrabiarek. Wprowadzono terminologie stosowaną przy tworzeniu postprocesorów i omówiono zagadnienia interpolacji kołowej, programowania w układzie 3+2 osie. W publikacji omówiono problemy związanie z pierwszym najazdem w obróbce 5-osiowej powierzchni krzywoliniowych.
Computer Aided Manufacturing (CAM) day-to-day progress and CNC Numeric Control capabilities make postprocessor requirements extremely high in terms of reliability, capabilities, and user expectations. This article is dedicated to selected issues of postprocessing resulting from practical applications; Obtained in postprocessor implementations on various types of machine tools. The terminology used for creating postprocessors was introduced, and discussed circular interpolation, 3 + 2 programming. This article discusses the problems associated with the first 5-axis machining.

Opis:
Despite substantial improvements CNC manufacturing is still based on dated practices and habits. This is mostly due to the use of ISO 6983 standard (G-codes) combined with vendor specific formats to exchange CAD/CAM/ CNC information. The manufacturing sector is consequently made of a collection of disconnected elements that are difficult to make communicate together. On the contrary STEP-NC approach offers many opportunities to overtake the current situation and rethink CAD/CAM/CNC numerical chains. However, the actual integration of STEP-NC in industrial concerns is quite limited. It is essential to couple this innovative approach with existing equipments. This paper shows how STEP-NC can be an efficient way to reconcile today's interoperability and efficiency demands by introducing the association of two manufacturing platforms: SPAIM, developed at IRCCyN (France), and which controls current industrial machine tools directly from STEP-NC files and IIMP from the University of Auckland (New Zealand), which realizes data portability between heterogeneous proprietary formats, process interoperability. As a result, both approaches lead to improved supervision and integration of the machining systems.

Opis:
In the era of Industry 4.0, the automation of processes in the life cycle of a product seems to be a necessity. Although programming CNC machines with CAM systems make it possible, it is necessary to effectively acquire knowledge about the programming process and technological requirements for effective automation. The paper presents a method for decomposition of knowledge about the CNC machine programming process based on acquiring knowledge from various sources, both from technologists as well as on the basis of analysis of archival CNC control programs. To decompose the programming process, it is proposed to apply the knowledge model described by various attributes. Verification of the method is shown in the process of knowledge decomposition for manufacturing special production tooling.

Opis:
The paper focuses on the algorithm for the recognition of manufacturing features defined in ISO 14649 (STEP-NC). First, the features defined in STEP-NC standard are discussed and then commonly used feature recognition methods are presented. Then the developed algorithm for recognition is presented in details starting with the discussion of STEP-NC features from the point of view of their recognition. The steps of the algorithm responsible for the recognition of profile based, transition and group features are presented. The software developed to verify the algorithm is also described. The final part includes the directions for the future research works. This paper adds to the works aimed to strengthen the position and use the full benefits of this new ISO 14649 standard.

Opis:
This paper presents a comparison of the impact of the programming methods of a CNC miller on the machining effects. As a part of the study, the test samples were made of the EN AW-2024 aluminium alloy. The CNC machining programs compared were developed with two programming methods: by inputting the CNC machining program directly from the CNC miller's control panel (machine level programming) and in a CAM software environment (CAM programming). The machining effect indicators adopted included: machining time, surface quality, and dimensional deviation of specific geometrical features. A measurement of the machining times revealed than the CAM programming reduced the machining time up to 20% from the machining time of the machine level programming. A conclusion stands valid that CNC machining programs developed in the CAM software environment are more efficient than CNC programming directly with the CNC miller control panel, most likely due to the machining path optimisation in CAM. In addition, given the experimental test results, it was found that smaller machined errors were also obtained for CAM programming. To conclude, the comparative analysis revealed that CAM programming provided better machining results than the machine level programming.
