Expert system to implement STEP-NC data interface model on CNC machine

Abstract

One of the issues in manufacturing is implementing the standard for the exchange of product data-numerical control (STEP-NC) data interface model on computer numeric control (CNC) machines. The most often used STEP-NC programming techniques for this implementation are indirect, interpreted, and adaptive. Because of the ease of integration with existing control systems, the performance of the interpreted method was noticeably superior to that of the indirect and adaptive approaches. This concept has resulted in the creation of several tools, systems, designs, algorithms, and methods. In this study, a new STEP-NC implementation system has been created, in which the interpretation has been done using entity-plus string-based (double layer) for more precise data extractions, the tool paths system can create facing, pocket, drill, bore, ream, countersink, side, slot, and contour operations, the output file generation system can create output as per interpreted and hybrid programming approac.....

New method to utilize STEP-NC data interface model for 3D printing

Kamran Latif

Abstract

Computer Numerical Control (CNC) systems are moving toward adopting the STEP-NC data interface model as their future standard. It has been developed for use in subtractive manufacturing with great success, but its use in additive manufacturing is still in the research and development stage. The incorporation of STEP-NC into the CNC system is still an open and present challenge. This article presents a method for making use of the STEP-NC data interface model for 3D printing. The method makes use of the CAD data of either the ISO10303 or ISO 14649 data interface model in part 21 of the physical file representation. A system is being developed to generate the tool paths necessary for 3D printing from STEP-NC part 21. It has been carried out on a 3D printer through the utilization of indirect and interpreted STEP-NC programming techniques. In order to carry out 3D printing operations, the system makes use of tools that are based on virtual component technology and are controlled by a part.....

Implementing circularity measurements in industry 4.0-based manufacturing metrology using MQTT protocol and open CV: a case study

Kamran Latif

Abstract

In the context of Industry 4.0, manufacturing metrology is crucial for inspecting and measuring machines. The Internet of Things (IoT) technology enables seamless communication between advanced industrial devices through local and cloud computing servers. This study investigates the use of the MQTT protocol to enhance the performance of circularity measurement data transmission between cloud servers and round-hole data sources through Open CV. Accurate inspection of circular characteristics, particularly roundness errors, is vital for lubricant distribution, assemblies, and rotational force innovation. Circularity measurement techniques employ algorithms like the minimal zone circle tolerance algorithm. Vision inspection systems, utilizing image processing techniques, can promptly and accurately detect quality concerns by analyzing the models surface through circular dimension analysis. This involves sending the models image to a computer, which employs techniques such as Hough Transfo.....

New system architecture and algorithm design for indirect STEP-NC implementation

Kamran Latif

Abstract

The adoption of STEP-NC on CNC machines has been one of the most enduring difficulties in daily operations. It is not outside of the realm of possibility to put this solution into practice by techniques that are indirect, interpretative, or adaptive. In this implementation, the interpreted approachs performance was noticeably better than the indirect methods. In this particular field, a substantial amount of investigation still needs to be carried out. This investigation focuses on a better interpreted STEP-NC programming paradigm, and a novel data interpretation approach along with algorithm design are presented. The system has been contributed with the latest hybrid method, which combines the indirect and interpreted strategies for constructing tool paths. In addition, the interpretation algorithm has been updated to incorporate a method for extracting data in two layers (entity and string). The entirety of the system is made up of a variety of software tools and algorithms for the p.....
