The motion control of profile milling flying saw based on controller MC206
The profile milling flying saw is able to achieve cut-to-length on moving circular and square pipe, this article highlighted the specific application of the controller MC206 in controlling the motion of the profile milling flying saw and completed the design of the corresponding program using Motion Perfect2 software, which is supported by the controller. Introduce the controller MC206 to the control system of profile milling flying saw is not only be able to achieve the continuous cutting on moving pipes with various shapes, but also increase the cutting speed and accuracy.

A New Vacuum Pressure Infiltration CFRP Method and Preparation Experimental Study of Composite
In order to prepare a carbon-fiber-reinforced polymer composite (CFRP) with ideal microstructure and properties, a new vacuum pressure infiltration CFRP method is proposed based on an analysis of existing CFRP preparation process methods. Research on composite material preparation systems was carried out by using this new method principle. The system mainly includes a fiber pre-forming module, a vacuum heating infiltration module, a hot-press curing molding module, and a data acquisition control module. Under the conditions of natural curing at 0 MPa + 6 h + 25 °C, vacuum heating curing at –0.05 MPa + 30 min + 80 °C, and hot-press curing at 0.7 MPa + 5 min + 50 °C, a two-dimensional (2D) CFRP with excellent microstructure and properties was successfully prepared. Observing the microstructure of the prepared composite material, it can be found that the inside of the composite material was sufficiently and uniformly infiltrated, and common preparation defects such as holes and delamination were effectively controlled. Through the performance test, the bending strength of the material reached 790 MPa.
