This paper discusses the development of a parametric (macro) program for processing a hyperbolic surface on a CNC lathe machine. Analytical dependences have been used to develop the macro program, as a result of which the CNC (computer numerical control) automatically calculates the coordinates of the intermediate points of the tool trajectory. The WHILE cycle operator is used to run the tool. Macro program functionality has been verified in a virtual environment using Vericut.

An open double coordinates computer numerical control (CNC) system was developed, which was based on PC and PMAC motion controller card. A miniature and teaching CNC lathe machine was developed with a simple structure, low cost, small volume and suitability for teaching. The CNC system had the advantages of 2-axis linkage, program editing, manual operation, inching operation, simulation processing operation, automatic operation and dynamic display of the tracing. The system was based on the Windows XP platform. Its interface was friendly and it was convenient to manipulate.

In order to study the highly efficient and stable cutting of computer numerical control lathe (CNC lathe), this paper established a dynamics model of chatter turning system on tool side, and analyzed the influences of the chatter stable lobes about the CNC lathe system’s overlap coefficient, cutting rigidity coefficient in unit width, main vibration system’s damping ratio, and observed the chatter effects about the chatter stable lobes in different regions by experimental methods. Research shows that the choice of the cutting speed in the stable regions can significantly increase the cutting width, and improve the efficiency of cutting.

Abstract UGIMA NSU and UGIMA 303 are the same grades designated differently for the European and North American markets, respectively. They are resulfurized grades with calcium added. Carefully controlled steelmaking results in a composition with oxides that have a low melting point and produce a lubricating effect during machining. Gains in the cutting conditions of 25 to 50% are typical on computer numerical control (CNC) lathe or classical machine work. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-709. Producer or source: Ugine-Savoie. Originally published March 1998, revised September 1998.

Abstract UGIMA 4570 is a resulfurized grade with calcium added. The steelmaking is carefully controlled and produces a composition with low-melting-point oxides, which produce a lubricating effect during machining. Gains in the cutting condition of 30 to 70% are typical on computer numerical control (CNC) lathe or classical machine work. The alloy is similar to UGIMA NSU but contains additional copper. This datasheet provides information on composition and physical properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-713. Producer or source: Ugine-Savoie. Originally published April 1998, revised October 1998.

High-quality material manufacture requires the improvement of the computer numerical control (CNC) machine performance. Such task can be achieved by considering the tool trajectory, in which it is important to minimize the acceleration and jerk levels. Previous research works are focused on providing smooth movements at most with C2 continuous trajectories, and the results of using C3 continuity in the trajectory are not evaluated. The contribution of this study is the design of a methodology for obtaining C3 tool trajectories while acceleration and jerk levels are constrained through adaptive feed-rate. C3 and C2 trajectories are executed in a CNC machine. Speed, acceleration, and jerk are monitored in order to validate the proposed methodology and to analyse and quantify the differences between using C2 and using C3 trajectories.

In order to meet the development demands for high-speed and high-precision of Computer Numerical Control (CNC) machine tools, the equipped CNC systems begin to employ the technical route of software hardening. Making full use of the advanced performance of Large Scale Integrated Circuits (LSIC), this paper puts forward using Field Programmable Gates Array (FPGA) for the functional modules of CNC system, which is called Intelligent Software Hardening Chip (ISHC). The CNC system architecture with high performance is constructed based on the open system thought and ISHCs. The corresponding programs can be designed with Very high speed integrate circuit Hardware Description Language (VHDL) and downloaded into the FPGA. These hardening modules, including the arithmetic module, contour interpolation module, position control module and so on, demonstrate that the proposed schemes are reasonable and feasibility.
