Automated Process

With the ever-increasing importance of e-commerce/e-business in the manufacturing, traditional standalone CAD/CAPP applications are evolving into web-based applications deployed via the Internet. This paper presents a unique web-based application for automated process planning and NC code generation for mill-turn parts. The application is targeted at a wide range of users. It requires no special software or CAD package at the user’s end, and can be used even by people with virutally no manufacturing knowledge. At the same time, it is also a valuable service for manufacturing experts. This application uses client/server architecture and is developed using Java technologies. This web-based application can be accessed via Internet using any standard web browser with JRE (Java run-time environment), and Java Web Start is used to deploy this application. For wide usability, the application supports easy part specification and automated process planning. Once the part is designed, the user may request NC code generation. The process planning kernel on the server automatically executes all process planning tasks like machinable volume identification, operations sequencing, parameter selection, etc. and generates an intermediate Cutter Location (CL) code. The Cutter Location code is quite generic and can be adapted for any machine using the respective post processors. The interface is also capable of displaying the tool path for verification. The NC code is generated based on the post processor selected by the user and can be downloaded to the client machine if the user is satisfied. It is hoped that this application will develop into a pay-per-use instant NC code generation web service for novices and experts; such a service is currently not offered anywhere on the Internet.

The postprocessor is essential for machining with five-axis machine tools. This paper develops one universal postprocessor for table-tilting type of five-axis machine tools without rotational tool center point (RTCP) function. Firstly, positions of two rotary axes and the workpiece in the machine coordinate system (MCS) are introduced into the kinematic chain of the five-axis machine tools. The uniform product of exponential (POE) formula of the tool relative to the workpiece is established to obtain the universal forward kinematics. On this basis, the postprocessor of table-tilting type of five-axis machine tools is developed. The calculation of rotation angles of rotation axes is proposed in details, including the calculation of double solutions, the determination of rotation angles of C-axis and the selection principle of the shortest path of rotation angles. Movements of linear axes are calculated with rotation angles of rotary axes. The generated movements of all axes are actual positions of all axes relative to their zero positions, which can be used for machining directly. The postprocessor does not rely on RTCP function with positions of rotary axes and the workpiece in MCS. Finally, cutting test in VERICUT and real cutting experiments on SmartCNC500_DRTD five-axis machine tool are carried out to verify the effectiveness of the proposed postprocessor.

Student laboratories have always played a key role in the engineering education at Stevens Institute of Technology (SIT). Recently, SIT has designed and implemented several innovative Web-based tools for engineering laboratory education and evaluated their learning effectiveness in pilot deployments in various engineering courses. These Web-based tools include both remotely operated experiments based on actual experimental devices as well as virtual experiments representing software simulations. These tools facilitate the development of learning environments, which - possibly in conjunction with traditional hands-on experiments - allow the expansion of the scope of the students' laboratory experience well beyond the confines of what would be feasible in the context of traditional laboratories. This becomes possible because of the scalability of resources that are shared through the Web and the flexibility of software simulations in varying the characteristic parameters of the experimental system under investigation. Further educational benefits of the proposed laboratory approach are that asynchronous learning modes are supported and discovery-based self-learning, of the students is promoted. This paper will present the details of the approach taken at SIT in integrating these Web-based tools into a comprehensive student laboratory experience. As an example for the implementation of such Web-based experiments, an Industrial-Emulator/Servo-Trainer System will be described, which is used at SIT in a junior-level course on mechanisms and machine dynamics.

This paper describes a novel method for automated process planning for rough boring of turned components with arbitrary internal geometry from a semi-finished stock. Earlier work has been reported on process planning for boring of components with monotonic internal geometry made from bar stock. This paper addresses the more general problem of process planning of parts with non-monotonic internal feature list from arbitrary given initial geometry, i.e., from a casting or from a semi-finished stock. With the algorithms developed, we are able to achieve full automation of all aspects of the process plan, including operations sequencing, parameter selection, NC code generation, etc. Thus, it becomes possible to go from design to NC code in a fully automated fashion. In the present work we focus on a tightly defined part family, which results in very simple but robust automation algorithms. This is in contrast to much of the reported work on automated process planning, which generally targets broad part families, leading to complex algorithms that fall short of complete design-to-NC automation.

FrameWeb (Framework-based Design Method for Web Engineering) incorporates concepts from categories of frameworks commonly used in the development of Web-based Information Systems into design models, defining the syntax of such models with meta-models. Based on Model-Driven Development (MDD) techniques, a CASE tool called FrameWeb Editor was built. In a separate eff ort, a code generation tool was proposed, but did not use the method’s MDD foundations. In this paper, we report on the integration of the code generator into the FrameWeb Editor and the FrameWeb meta-model.

Remote laboratories are becoming increasingly popular in academic arena due to availability of web-based technologies and infrastructure. Remote Labs are equipped with real instruments, where experiments are performed by controlling the instruments and observing the real data from a distant location through computer networks. They provide for student centric laboratory experience as students can perform experiments at their own convenience and requirements. Further, Remote Labs reduce management of work involved in running conventional laboratories. This paper describes design and implementation of such an experimental setup for performing characterization experiments on Transducers in general and Acceleration and Speed Transducers in particular from a remote location. The experiment can be made accessible to anyone over a TCP/IP network with a standard Web Browser, relevant plugin, and permission. This paper demonstrates that traditional experiments on sensors and transducers can be successfully made available online to both on-campus and off-campus students at their own schedule and convenience.

Registration problems that are still using the form that led to long queues so that the assessors of prospective students are often hassles, besides the highest and lowest value of UAS as a reference the admissibility of a prospective new students can only be seen by visiting directly. So here was made Applications Web-Based Admission to solve the above problems. Based on the background of the issues above, it will build a system of Admission Selection System Based Web by using a linear sequential software development (waterfall), which has several stages including software requirements analysis phase, the design phase, the code generation phase, phase testing, and maintenance phases., so that the resulting applications have advantages in data processing. In this application also can map the school, where the making of the map using Google Maps to produce a map that has a location corresponding to the location of the original condition.
