Advancement in manufacturing processes has drawn preeminent interest from researchers and industry, it makes the process of manufacturing more productive and capable of high efficiency. Advancement of technology has been done by several approaches to combine different manufacturing processes with similar objectives of increasing material removal rate, improving surface integrity, reducing tool wear, reducing production time, and extending application areas. A combination of different processes has been called ‘Hybrid’ processes by various researchers, engineers, and industry expert. Hybrid processes open new opportunities and applications for manufacturing various components that are not able to be produced economically by processes on their own. This review report starts with the classification of current manufacturing processes based on the nature of the processing. The main part of this report is reviews of existing and widely used manufacturing processes that recently reported in a decade. Purpose of this report to produce an overview of these different processes by reviewing various research papers.

The demands on today’s products have become increasingly complex as customers expect enhanced performance across a variety of diverse and changing system operating conditions. Reconfigurable systems are capable of undergoing changes in order to meet new objectives, function effectively in varying operating environments, and deliver value in dynamic market conditions. Research in the design of such responsive and changeable systems, however, currently faces impediments in effective and clear discourse due to ambiguity in terminology. Definitions of the terms flexibility and reconfigurability, two related concepts in reconfigurable system design, are explored based on their original lexical meanings and current understanding in design literature. Design techniques that incorporate flexibility both in the design (form) and performance (function) space are presented. Based upon this literature survey, a classification scheme for flexibility is proposed, and its application to reconfigurable system design is explored. This paper also presents recent methodologies for reconfigurable system design and poses important research questions that remain to be investigated.

“…Re‐configurable mold manufacturing (Kelkar et al , 2003, 2005) is a novel molding process, in which the part surface is approximated using discrete pins in order to generate the part mold cavity. The basic component of the system is a mold block, which holds a matrix of discrete pins on each of its faces.…”

“…As shown in Figure 2, the input to the re‐configurable molding system (Kelkar et al , 2003, 2005), is a surface model of the part with the surface normal information, as shown in Figure 2(a). This model is analyzed to determine the best face of approximation for each point of the part surface.…”

PurposeThe objective of this paper is to develop geometric algorithms and planning strategies to enable the development of a novel hybrid manufacturing process, which combines rapidly re‐configurable mold tooling and multi‐axis machining.Design/methodology/approachThe presented hybrid process combines advantages of both reconfigurable molding and machining processes. The mold's re‐configurability is based on the concept of using an array of discrete pins. By positioning the pins, the reconfigurable molding process allows forming the mold cavity directly from the object's 3D design model, without any human intervention. After a segment of the part is molded using the reconfigurable molding process, a multi‐axis machining operation is used to create accurate parts with better surface finish. Geometric algorithms are developed to decompose the design model into segments based on the part's moldability and machinability. The decomposed features are used for planning the reconfigurable molding and the multi‐axis machining operations.FindingsComputer implementation and illustrative examples are also presented in this paper. The results showed that the developed algorithms enable the proposed hybrid re‐configurable molding and multi‐axis machining process. The developed decomposition and planning algorithms are used for planning the reconfigurable molding and the multi‐axis machining operations. Owing to the decomposition strategy, more geometrically complex parts can be fabricated using the developed hybrid process.Originality/valueThis paper presents geometric analysis and planning to enable the development of a novel hybrid manufacturing process, which combines rapidly re‐configurable mold tooling and multi‐axis machining. It is expected that the proposed hybrid manufacturing process can produce highly customized parts with better surface finish, and part accuracy, with shorter build times, and reduced setup and tooling costs.
