The specific indicators are as follows: working stroke: X50mm, Y40mm, Z20mm spindle speed: 1200rpm milling cutter diameter: 4mm (double-edged) 35 machine tool numerical control principle and system experimental device development pulse equivalent: 0.01mm (3 phase 6 beat ring) / 0.02mm (3 phase 3 beat ring) Stepping motor: 45BF005 (3-phase 1.5/0.75, 27V/2.5A, 0.2Nm) Displacement sensor: X-axis CWY-50 (range 050mm) Y-axis CWY-40 (range 040mm) Z Axis CWY-20 (range 020mm). Characteristics and functions of the experimental system The numerical control principle of the machine tool and the system experimental device from the principle design to the implementation method have the following technical features: (1) Based on the PC platform design, the existing hardware resources of the school can be fully utilized to avoid repeated investment. (2) Using C language programming, students are easy to master, and can also complete a variety of real-time control functions by means of rich software resources and mixed programming of high and low languages. (3) The multi-CPU upper and lower machine structure form can solve the contradiction of timing tension and provide sufficient time resources for the implementation of control algorithm 36 experimental technology and management. (4) Building block type and modular software design ideas provide guarantee for improving the success rate of students' experiments, and solve the contradiction between the huge CNC system control software and the limited experiment time in the teaching process. (5) The design of open experimental software allows students to fully participate and make full use of their initiative, not only to achieve the intended purpose of the experiment, but also to enable their ability to be comprehensively trained. (6) Both the open-loop numerical control system experiment and the closed-loop numerical control system experiment can be carried out to meet the needs of the development of modern numerical control technology. (7) The hardware and software of the entire experimental device are fully transparent, and students can develop their own complete CNC software or conduct courses and graduation design.
