Abstract:

Optimizing the sequence of operations (SOS) is important factor in improving the productivity of machines and reducing the production cost. However, CNC programing packages are available and have been significantly improved program generation for CNC machines, but in most of these packages the SOS optimization is not considered. This paper, introduce an efficient solution to optimized SOS for multi-cutting tools operations located asymmetrically. A well-known genetic algorithm (GA) is utilized to solve the SOS problem. After optimizing SOS, its related CNC program will be generated. The operation locations are considered as cities of Traveling Salesman Problem (TSP), and the cutting tool is considered as traveling salesman, by this way, TSP methodology can be modified to formulate the SOS problem. GA and the modified TSP can be incorporated into CNC programming packages to optimize the SOS before the program generation.

Abstract:

PMAC motion controllers serve not only as a receiver of the orders from CNC systems of many kinds, but also as a controller of the motion of machine tools’ axles. With G83 as an example, a code commonly seen in the processing cycle of deep holes in CNC machining centers, it is advisable to come up with a method to write a special set of subprograms to invoke PMAC motion controllers with the application of G-code. Based on the method, case programing and machining simulation can be launched. Experiments justify that the method obtained can realize the compiling of fixed cycles with the use of G-code and, in turn, boast substantial significance in the development of open CNC processing machine tools.

Abstract:

A programming to make parts are CNC Programming (Computer Numerical Control Programming) for machines. An NC program consists of a sequence of instructions that control the motion and automatic sequences of an NC Machine to perform a particular processing task. In a general sense, the term NC programming refers to the creation of control data for machining workpieces on NC and CNC machines. NC programming has a decisive influence on the cost-effectiveness and profitability of NC manufacturing. The selection of a programming system is mostly guided by the need for software that is suitable for the application at hand, readily available, and as universally applicable as possible.

Abstract:

The contouring precision of computer numerical control (CNC) machine tools relates to whether the dynamic performances among all the axes match or not. In general, the cross-coupled controller (CCC) is a more efficient approach to enhance contouring precision than single-axis servo controller. Note that the contouring error CCC can not be separated from pathway programming in multi-axis linked servo system. In order to obtain satisfied contouring precision, the CCC approach connected with non-uniform rational basis spline (NURBS) curve interpolation is researched in detail in the paper. Above all, an "arc approximation algorithm" contouring error computing model is developed, according to the real cutter positions from each axis feedback and the interpolation dots stored in the interpolation buffer. Then the contouring error correction quantity PI control and distribution algorithm is put forward by introducing a zoom coefficient. The contrast experimental results on the CNC experiment table show that the developed CCC approach can reduce contouring error and improve tracking performance further.

Abstract:

Abstract This paper presents a comparison of the impact of the programming methods of a CNC miller on the machining effects. As a part of the study, the test samples were made of the EN AW-2024 aluminium alloy. The CNC machining programs compared were developed with two programming methods: by inputting the CNC machining program directly from the CNC miller's control panel (machine level programming) and in a CAM software environment (CAM programming). The machining effect indicators adopted included: machining time, surface quality, and dimensional deviation of specific geometrical features. A measurement of the machining times revealed than the CAM programming reduced the machining time up to 20% from the machining time of the machine level programming. A conclusion stands valid that CNC machining programs developed in the CAM software environment are more efficient than CNC programming directly with the CNC miller control panel, most likely due to the machining path optimisation in CAM. In addition, given the experimental test results, it was found that smaller machined errors were also obtained for CAM programming. To conclude, the comparative analysis revealed that CAM programming provided better machining results than the machine level programming.

Abstract:

Many parts such as craftworks and hand draw pictures were manufactured based on the image. Their shape was irregular and couldn't measure accurately. And the dimension was not labeled definitely. So the CNC machining code couldn't directly generate. The paper studied the methods and the machining performance of this kind of part. The digital image could be obtained through the scanner or the digital camera, and pretreated by computer. The digital images were transferred into the vector document and the boundary dimension parameters could be gotten. The NC instruction was generated through the automatic module. Finally the procedure of programming and process was verified by an image

Abstract:

We introduce the Concurrent Collections (CnC) programming model. CnC supports flexible combinations of task and data parallelism while retaining determinism. CnC is implicitly parallel, with the user providing high-level operations along with semantic ordering constraints that together form a CnC graph. We formally describe the execution semantics of CnC and prove that the model guarantees deterministic computation. We evaluate the performance of CnC implementations on several applications and show that CnC offers performance and scalability equivalent to or better than that offered by lower-level parallel programming models.

Abstract:

Post-processing technology is the key to CNC automatic programming technology and an important module of the CAD / CAM system. Post-processing technology converts the NC program that is produced by the CNC automatic programming tool into the file that can be identified by CNC system. Moreover, the generated tool path files must match with the CNC system. Post-processing techniques and UG software are briefly introduced. Using them, a post-processor for FANUC CNC systems is created. The program that generated by the special processor is contrasted with the general processor. The results illustrat that using the dedicated post-processor in engineering applications can improve programming efficiency and processing reliability.

Abstract:

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.

Abstract:

This workpiece process is: to find out how to transfer images from Auto CAD software to the Q plus CELL Milling Cnc software, and to find out how to transfer programs from the CNC Milling QELL KELLER software to the TU 3A CNC milling machine. The making of this workpiece uses three main media, namely Auto CAD 2000 software, CNC Milling KELLER Q plus software, and TU 3A CNC milling machine. The process of making the workpiece starts from making the workpiece design in Auto CAD software which is then stored on the CDR via DFX data. The design of the workpiece contained in the CDR is then transferred to CNC Millling KELLER Q plus software via Geometry. in Geometry, the design of the workpiece is dimensioned. Completed from the Geometry the workpiece design is included in the Work plan to be processed so that it can be simulated to move to a CNC program to convert the graphical language into a numeric language so that it can be read by a CNC machine. The programming results from the CNC KELLER Q plus software are then recorded to be executed on the CNC TU 3A milling machine to obtain the workpiece in accordance with the design in AutoCAD. Programming results from CNC Milling KELLER Q plus software cannot be directly used on the TU 3A milling machine (EMCO), because the programming language used is different. Programming language in CNC Milling KELLER Q plus software uses the DIN 66025 standard, while the CNC TU 3A (EMCO) milling machine uses ISO standards, so it needs to be converted first.

Abstract:

This paper presents a method to simultaneously increase the accuracy and decrease the calculation time for complex tool path programming in multi-axis machining centers. Examples of complex parts requiring such complex tool paths include various kinds of turbine blades, pump-forcing augers, teeth surfaces, etc. It explains the creation of topological structures on the basis of analytical spline curves with floating range definitions. The method for tool path calculation accommodates the specific requirements for multi-axis milling. The algorithms developed are the foundation for the CAD/CAM software that allows for NC programming and machining on 5-axis centers employing any design model. Industrial tests reveal a 70-80% reduction of NC programming time of parts with complex surfaces, reduced machining time of approximately 40-50% using basic high-speed cutting methods and custom-made tools. The advanced methods of NC programming result in substantially increasing machining accuracy.

Abstract:

Many difficulties may be encountered when preparing CNC programs using conventional programming or canned cycle programming. This study tries to establish a practical common algorithm allowing the drilling of holes arranged in multiple circular patterns. The programmed algorithm can easily be adapted to any modern CNC unit to create a user cycle or subroutine. To test the capabilities of this algorithm, two case studies were developed. A number of samples were produced successfully. The new algorithm shows high efficiency in the part program establishment and offers the advantage of decreasing the encoding errors.

Abstract:

AbstractThis paper proposes a set of four elliptical features that can enhance the programming capabilities of a modern CNC system. Namely, a real-time interpolation algorithm for motion generation along an ellipse and its offset, machining of an elliptical pocket, and drilling a series of equidistant holes along an elliptical path. The paper analytically describes the implementation of the new functions while the G-codes, along with their complementary requisite data needed to be introduced in the CNC part program, are exemplified with simulation and actual machining tests for each feature.

Abstract:

Owing to the deficiency of machining non-circular curve by manual programming in CNC system, the universal macro-program of machining non-circular curve based on the ellipse curve in CNC turning of the FANUC system is developed by adopting analytical and inductive approach. The real application of machining ellipse and parabola curves are also proposed in this paper, which showed that the universal macro-program is flexible and convenient. The programming efficiency and quality is increased effectively while machining any other non-circular curve works.

Abstract:

The characteristics of open CNC system and the current several open CNC system models are introduced in this paper. In order to overcome the contradiction between the frequent changes demand and the closure of the traditional system, the open CNC system software and hardware architectures were investigated based on web-collaborative design and development, which improve the system development efficiency. Using the Windows XP operating system as a software platform, the Visual C++ 6.0 object-oriented programming language is adopted to design the CNC drilling control software based on the "PC + NC" the model and modular co-design methods, which improve the openness of the CNC system.
