“…One of the rules for the assignment of features to setups is the consideration of tool approach directions (TAD) as presented, among others, in research papers of Gologlu (2004) or Liu and Wang (2007). As indicated in these papers, features with the same TAD can be grouped into feature clusters and machined within one setup.…”

“…In most CAPP-related publications, geometric interactions between features, the data sets concerning dimensions and tolerances are used for sequencing features within each individual setup, as assumed in the design schemes of Gologlu (2004), and also Liu and Wang (2007). The problem of embedding, in current CAD models, non-geometric technological information, such as dimensional and geometric tolerance, surface roughness and hardness, that is necessary for CAPP, is also discussed by Zhou et al (2007).…”

“…Similarly, Park (2003) implies the possibility for the aggregation of machining operations with the reference to unit volume decomposition for complex features. Apart from the geometric reasoning rules, just Liu and Wang (2007) proposed the use of more detailed knowledge-based rules for determining machining precedence constraints, with regard to the sequence between setups and also to feature sequencing within each consecutive setup. Wang and Shen (2003) advocate a decentralization in CAPP system architecture and develop a novel method of distributed process planning (DPP) characterized by increased system responsiveness, correspondingly with the requirements of dynamic, reconfigurable and distributed manufacturing environments.…”

“…The application of feature-based process planning has gained ground recently in supporting the efficient CAD and CAM integration (Gao et al 2004;Zhou et al 2007). Features are assumed inherently as a main factor in such an integration effort because of the association of various design, engineering and manufacturing data used by CAPP (Liu and Wang 2007;Tanaka and Kishinami 1998;Wang et al 2006). Proper sequencing of machining features still remains a challenging issue in CAPP due to its complexity and adherence to the class of nondeterministic polynomial-time problems (Mokhtar and Xu 2011).…”

Efficacious integration of such CAx technologies as CAD, CAM and CAPP still remains a problem in engineering practice which constantly attracts research attention. Design by feature model is assumed as a main factor in the integration effort in various engineering and manufacturing domains. It refers principally to feature clustering and consequently operation sequencing in elaborated process plan designs. The focus of this paper is on CAPP for parts manufacture in systems of definite processing capabilities, involving multi-axis machining centres. A methodical approach is proposed to optimally solve for process planning problems, which consists in the identification of process alternatives and sequencing adequate working steps. The approach involves the use of the branch and bound concept from the field of artificial intelligence. A conceptual scheme for generation of alternative process plans in the form of a network is developed. It is based on part design data modelling in terms of machining features. A relevant algorithm is proposed for creating such a network and searching for the optimal process plan solution from the viewpoint of its operational performance, under formulated process constraints. The feasibility of the approach and the algorithm are illustrated by a numerical case with regard to a real application and diverse machine tools with relevant tooling. Generated process alternatives for complex machining with given systems, are studied using models programmed in the environment of Matlab software.

“…Feature recognition process becomes more intriguing due to possible geometric interaction of features. Volumetric or surface collisions between features' geometry have affecting consequences on their recognition, interpretation, and machining sequence [30,31]. Feature interaction and multiple interpretations are not addressed in STEP data model.…”

Practical implementation of a STEP-based architecture to provide a fully integrated and interoperable platform of data exchange has always been an intriguing issue. A variety of CAD/CAM environments are struggling to embed and support STEP standard and its protocols in order to seamlessly operate within global data exchange. However, apparent paucity of efficient and reliable structure for data communication, manipulation, and restoration has remarkably hindered the desired progress. In this paper, taking these shortcomings into account, a practical architecture is introduced and STEP-based agents are implemented and installed on the platform. Moreover, feature recognition, interaction, and machining precedence as crucial issues of CAD/CAM research have been considered in developing the interoperable platform. Seamless integration and interaction of CAD/CAM modules are provided in the proposed system. The prototype is finally verified and discussed through a case study.

Digital twins in manufacturing plays a key factor for the digital transformation. A necessary component of any digital twin in manufacturing is a geometric model of a workpiece as it is processed through steps. DT requires solid 3d models, machining features, and information regarding machines, tools, and its constraints such as initial setup, machining direction, etc. The objective of this paper is to generate alternate feature interpretations to identify geometric constraints, machine and tool requirements, and stock materials to generate flexible manufacturing plans that fit a defined criterion. In this study we propose using the IMPlanner system to retrieve a 3d model from a CAD software, read its geometric features and convert them into possible machining features. This information along with information from the database of stock materials, tools, machines, and tolerances, the system generates several feature interpretations, thus offering a more flexible manufacturing plan.
