Reverse engineering represents a method to retrieve information from an existing product, information which are then used for designing a new product or to reproduce it in order to make spare parts. In this paper is presented a case study on making a spare part of complex shape from a worn part. There are presented the stages of acquisition of data by scanning, the use of reverse engineering for the realization of the 3D model, the virtual manufacturing and then the machining of the workpiece CNC machine tools.

The paper deals with the application of Reverse Engineering (RE) in the process of redesigning and manufacturing of a printer spare part. The paper presents the devices for transfer of a damaged printer part into a digital model by non-contact three-dimensional (3D) digitization. The paper discusses the 3D computer-aided designing (CAD) of a model with CAD software based on a digitized real part. The paper presents two proposals for spare part manufacturing: a) manufacturing by computer numerical control (CNC) milling, which is projected and programmed in computer-aided manufacturing (CAM) software with regard to production potential of selected CNC machine tools; b) manufacturing by Rapid Prototyping (RP) technology. The article concludes with a comparison of the proposed methods of manufacturing of printer spare part in term of production time.

PurposeThe purpose of this paper is to identify the main reasons for spare parts logistics failures and address logistics distribution design in order to achieve the desired level of after-sales maintenance service.Design/methodology/approachThis research is based on an empirical case study on a large corporation providing worldwide with retail banking hardware, software and services. The case study focuses on the automated teller machine (ATM) part of activities, with a focus on the spare parts distribution and after-sales service network in the Eastern Europe.FindingsThe proposed network solution of multiple distribution centers with short-cut distance saving approach will enable the case study company to redesign their spare part logistics architecture in order to achieve short response time. Research findings reveal possible spare parts delivery delays and thus the service-level agreement failures with clients in the case study company.Research limitations/implicationsThis research covers a particular supply chain environment and identified research gaps. It discusses a time-based responsive logistics problem and develops a conceptual framework that would help researchers to better understand logistics challenges of installed equipment maintenance and after-sales service.Originality/valueThis case study research shows the “big picture” of spare parts logistics challenges as vital part of installed equipment after-sales and maintenance service network, as well as emphasizes how the unique context of a market like Russian Federation can set-up a distribution network efficiently. Strategies applied to handle such service-level failures, reverse logistics aspects of repairable and non-repairable spare parts to such large ATM after-sales service network based on this longitudinal case offer value for similar scale companies.

Distribution of hobbing machine spare parts is a key factor to improve the efficiency of service-oriented spare part allocation. In order to minimize the distribution route, the distribution model of hobbing machine spare parts with time limits was put forward. The modified savings algorithm was adopted to solve the model. To improve the loading rate of classic savings algorithm, the modified savings algorithm allowed the split delivery according to customers' requirements. A case study verified that the application of modified savings algorithm ensured the shortest distribution route and improved the vehicle loading rate.

Rich Information

STEP-NC is a new data model for data exchange between CAD / CAM and CNC, which provides rich information for CNC machine tools and tells CNC “what to do”rather than “how to do”, overcomes many shortcomings of the traditional G&M codes and has become a hot research issue now. How to efficiently and cost-effectively generate the STEP-NC program is a very crucial problem. Although some domestic scholars have done some research about STEP-NC program generation, most of them do second development base on ST-Developer software. The paper developed a STEP-NC program generation module by using the VC++6.0 and CAD / CAM software. The module can read AP203 file generated by CAD system, identify manufacturing features according to its geometry information and conduct process planning to generate STEP-NC file according to ISO14649 standard. This module has been proved effectively by an instance.

Machine Communication

Modern CNC machine tools constitute advanced mechatronic systems. Numerous works are undertaken on the development of new intelligent control systems for CNC machine tools [1–5] equipped with unique diagnostic systems. One of the development directions of CNC control systems is exploring new forms and techniques of operator-machine communication as well as new, simpler machine tool programming procedures. Nowadays, there are many techniques for programming CNC machine tools [6], [7]. These techniques have taken a variety of forms both due to historical limits of technology and various environmental requirements. Despite the existence of complex control systems for operation and programming CNC machine tools or CAD/CAM systems facilitating the generation of a machining strategy for complicated elements, there is a demand for machine tools that are easier to operate, and therefore do not require advanced programming skills for operation.
