The Development of New STEP-NС Code Generator (Milling STEP Coder)

This research explored ISO 14649 together with ISO 6983 and utilize STEP-NC in overcoming the problems of G & M code and at the same time take advantage of the current advances in computing and controllers. A new STEP-NC Code Generator called Milling STEP Coder, which focuses on the milling process that are able to generate STEP-NC codes based on ISO 14649 Part 11 was developed. This system also has the capabilities to visualize the STEP-NC codes generated in a parent to child relationship tree-view structure, as well as give an image visualization of how the end machining will appears. The developed Milling STEP Coder uses Software Prototyping Model as its software development methodology, instead of the normal waterfall model, as prototype is a valuable mechanism for gaining better understanding of the system requirements. A small-scale mock up of the system was developed following an iterative modification process. The advantages of the proposed Milling STEP Coder program was verified and evaluated. The Milling STEP Coder can generates STEP-NC codes through a STEP-NC compliant interface and will give industries and academician more in-depth understanding and confidence to make the switch from G & M code to STEP-NC.

Architecture Framework

Abstract The use of virtual prototyping tools typically results in products with lower costs, better quality, and shorter development cycles. However, there are many interface/configuration problems that occur in the process of obtaining a design solution using the typical gamut of virtual prototyping tools. This paper presents the architecture, design, and implementation of a framework to support the integration of the multiple software systems used in the virtual prototyping of mechanical components. Some of the virtual prototyping software systems considered in the implementation of this framework were customer input systems, solid modeling systems, finite-element systems, knowledge-based systems, NC code generator systems, and virtual assembly systems. There is a pressing need for the different software systems to talk to each other while transferring the required data at varying levels of abstraction without compromising data integrity. Of special significance is the fact that the philosophy of the framework is widely applicable to any mechanical system, and is almost independent of specific software utilities. Thus, this design incorporates a clear path towards expansion to encompass other independent tools/systems. The architecture was designed using object-oriented methods. The framework was very successfully demonstrated for a well-defined subset of software systems being used at Isothermal Systems Research (ISR) Inc., a leader in proprietary spray cooling systems for multi-chip modules. This framework effectively supports the strong industry push towards integrated design, manufacturing, and virtual prototyping. The work presented in this paper was supported by an SBIR grant from the Department of Commerce, DOC contract 50-DKNB-5-00117.

Tool path generation, post-processing and verification and simulation of NC program are key technologies which are investigated in this research for manufacturing impellers. Generation of tool path aims at producing the cutting tool path. Post-processing transforms the cutter location file (CLSF file) of the tool path to the NC code which NC machine can recognize. Verification and simulation of NC program aims at proving the accuracy of program, thus the interference and collision can be avoided. When tool path is planned, increasing the machining efficiency during the rough and semi-finish milling process is the main consideration. Increasing machining accuracy is an important consideration for final finish milling.

Research in consumer science has proven that grocery shopping is a complex and distressing process. Further, the task of generating the grocery lists for the grocery shopping is always undervalued as the effort and time took to create and manage the grocery lists are unseen and unrecognized. Even though grocery lists represent consumers’ purchase intention, research pertaining the grocery lists does not get much attention from researchers; therefore, limited studies about the topic are found in the literature. Hence, this study aims at bridging the gap by designing and developing a mobile app (application) for creating and managing grocery lists using modern smartphones. Smartphones are pervasive and become a necessity for everyone today. Hence, a smartphone app that can facilitate the process of creating and managing grocery lists for busy and working people is beneficial. The design and development of the app followed the rapid application development methodology. First, the functional requirements were gathered through interviews and content analysis. Then, a prototype named SMART LIST has been developed based on the gathered requirements, and a field study was carried out to evaluate the usability of the prototype. The results of the evaluation suggested that SMART LIST is useful and easy to use. The respondents also satisfied with the functions for managing grocery lists offered by SMART LIST. The study contributes towards an understanding the system requirements and user interface of a mobile app for managing grocery list. It can be a reference model for developers and researchers in the area to develop similar apps or enhancing the capabilities in creating and managing grocery lists.

Five Axis

In this paper we present a novel mechanistic model of cutting process of the cylindrical tool by using the actual removal volume per tooth via NC simulation. The simulation kernel enables “virtually” cutting the workpiece in milling process per NC code, as well as calculating the removal volume per tooth which leads to predict the actual cutting force during simultaneous five-axis machining. Combined with the material removal simulation, the advanced mechanistic process model, which can enable the prediction of the cutting force and adjust the trajectory velocity of the cylindrical tools undergoing five-axis movement, is presented by applying the line integral along the cutting edge and taking the rake angle and cutting edge roundness into consideration. The novel methodology to adjust the cutting force by prevailing cutting tools undergoing multi-axis motion is to be validated by experiment and integrated into tool path planning systems.

Given the growing computational power of embedded controllers, the use of model predictive control (MPC) strategies on this type of devices becomes more and more attractive. This paper investigates the use of online MPC, in which at each step, an optimization problem is solved, on both a programmable automation controller (PAC) and a programmable logic controller (PLC). Three different optimization routines to solve the quadratic program were investigated with respect to their applicability on these devices. To this end, an air heating setup was built and selected as a small-scale multi-input single-output system. It turns out that the code generator (CVXGEN) is not suited for the PLC as the required programming language is not available and the programming concept with preallocated memory consumes too much memory. The Hildreth and qpOASES algorithms successfully controlled the setup running on the PLC hardware. Both algorithms perform similarly, although it takes more time to calculate a solution for qpOASES. However, if the problem size increases, it is expected that the high number of required iterations when the constraints are hit will cause the Hildreth algorithm to exceed the necessary time to present a solution. For this small heating problem under test, the Hildreth algorithm is selected as most useful on a PLC.
