Reconfigurable Machines form a new class of machines that are designed around a specific part family of products and allow rapid change in their structure. They are designed to allow changes in production requirements by changes in the machine mechanical configuration and structure. Reconfigurable machines might be designed for various types of production operations such as machining, inspection and assembly. This paper introduces characteristics and design principles of reconfigurable machines, and describes their features using an example of our new full-scale industrial prototype of a Reconfigurable Bore Surface Inspection Machine (RBSIM). In addition, the paper also describes briefly other three prototypes of Reconfigurable Machines that were developed during recent years in our center: (1) the Reconfigurable Machine Tool (RMT), (2) the Reconfigurable Inspection Machine (RIM), and (3) the Reconfigurable Assembly Machine (RAM).

Reconfigurable Machine Tool

A reconfigurable manufacturing system is one designed for rapid change in its structure, to quickly adjust its production capacity and functionality within a part family. Aiming at the diversity, cost and complexity of reconfiguration design, a method for evaluating the design scheme of a reconfigurable machine tool based on VIKOR is proposed. The module similarity between a reconfigurable machine tool and a prototype machine tool is defined, and on this basis, three quantitative evaluation indicators are established as follows: the module chain similarity determines the difficulty, effort, time and efficiency of machine tool reconstruction; the module interface complexity determines the feasibility and complexity of the disassembly and assembly of the reconfiguration module; and the reconfiguration cost determines the economic advantages of reconfigurable machines relative to fixed-structure equipment. According to three indicators, a multi-attribute decision-making method based on VIKOR is used to evaluate, calculate and sort the design scheme set of the reconfigurable machine tool, and the optimal feasible solution is obtained. An example of the reconfiguration design of a machine tool is analysed to verify the validity and feasibility of the proposed method compared with the methods of simple average weighting and technique for order preference by similarity to an ideal solution.

Automated tool changing of CNC machines reduces the cycle time of operations as most processes require a number of different tools to complete a task. The machine can be pre-loaded with the required tools and programmed to automatically retrieve the tools as required. CNC machines will often run unattended or work too quickly for manual intervention, so it is important that safety features and checks are built in to prevent damage. The purpose of this research project was to modify a tool changing system for a reconfigurable machine tool (RMT), which was previously developed in the Department of Mechatronics. The RMT is capable of performing milling, drilling and electric discharge machining (EDM). In this research, the automated tool changer (ATC) was developed and successfully integrated into the RMT, and interfaced with the machine controller. The redesigned ATC is able to provide fast, reliable and safe tool changing for a variety of tools.

Reconfigurable Machine Tool

The traditional structure of machines (such as lathe, milling, shaper, slotter, drilling and planer) has become questionable because of the modular concepts (such as modularity, scalability, convertibility, mobility and flexibility) and reconfiguration becomes a promising approach towards modular manufacturing machines, in which manufacturing techniques are independent of changes. In this area, reconfigurable machine tool (RMT) forms a new class of modular machines in current manufacturing scenario where the manufacturing industry put a strong pressure on good quality and price reduction. The capabilities of the machines tool and manufacturing systems in reconfigurable manufacturing system (RMS) change with each reconfiguration (both software and hardware modules). In this case, an approach is presented for reconfiguration of horizontal shaper machine for developing the modular shaper cum slotter machine in a manufacturing system by adding some auxiliary (like Scott Russel mechanism) and some basic modules and the reconfiguration features of traditional shaper and slotter machine are also discussed. The proposed approach is illustrated with a figure, which has been designed on 3-D design tool (solid-works software platform). It is expected that, this work will help designers and practising engineers by making them aware of the reconfiguration mechanisms on traditional shaper machine, which have become a necessity for the very survival of manufacturing by lowering the operational costs.

There has been very little research in the field of Reconfigurable machine Tools (RMTs). None of the past research developed a method to design a set of RMT configurations required to machine a part-family. This thesis presents a novel method to determine the functional specifications of the RMT configurations required to machine a part-family. The method is developed by firstly designing the RMT required to machine a single part. Thereafter, this method is extrapolated to suit the problem of a part-family. To design the RMTs for a single part, firstly, the part is decomposed into manufacturing features. Next, a novel method is developed to cluster the features. Each of these feature-clusters corresponds to a single RMT configuration. Based on the machining requirements of these RMT configurations, the modules are designed. These modules are assembled to form the final RMTs. The method is demonstrated by applying it to an example part.

Reconfigurable Machine Tool

This paper presents a novel concept to enhance the reconfigurability issues (i.e. convertibility, flexibility, etc.) of a small-scale reconfigurable machine tool (RMT) by combining multiple modules (both basic and auxiliary parts) and manufacturing operations on a single workstation. The proposed reconfigurable machine will reduce the overall space, transport time, ramp up time, reconfiguration time and interim storage space. Further, various characteristics of reconfigurability (such as scalability; convertibility, flexibility, etc.) and enablers of the machine tool have been discussed. The proposed design is illustrated with a figure, which is designed on a 3D design tool (solid-works software platform).This machine tool will perform six major cutting and finishing operations, namely, hacksaw cutting, milling, drilling, grinding, buffing and lathe operations on a single work platform.
