In this paper, the shape of the spinneret capillary was discussed, and optimized spinneret capillaries were successfully processed by a computer numerical control processing method which takes a C-shape silver electrode as the basic unit. Based on the optimised spinning process, a new type of square 8-hole hollow PET fibre was prepared by the experimental method.

Polyester fibre is the synthetic fiber made with man-made fibers. Its surface is smooth with the texture of fine linen. It has good flexibility and durability and is the best non-iron fibres. In order to promote the accuracy and reduce the quality deviation of melt spinning, the Taguchi method was adopted in the melt spinning process. The aim of the research is to enhance the optimization of the melt spinning process using the material polyester. First, the Taguchi method is applied to establish the design of experiment. An analysis of variance will be done to arrive at the significant factors that influence the melt spinning quality the most. Lastly, confirmation experiments verified the reproducibility of this experiment. Confirmed by the experiments, results showed that the obtained SN ratios were greater than the signal-to-noise ratio of nine orthogonal array experiments and this means the experiment is reliable.

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.
