    摘要:

    以解決機床控制過(guò)程中存在的抖振現象和控制誤差過(guò)高問(wèn)題為目的,在云環(huán)境下,利用PLC模擬量?jì)?yōu)化技術(shù),從硬件和軟件兩個(gè)方面優(yōu)化設計機床自動(dòng)控制系統。加設可編程邏輯控制器,改裝傳感器、電機與驅動(dòng)器,調整系統電路的連接方式,完成機床自動(dòng)控制硬件系統的優(yōu)化。根據機床生產(chǎn)任務(wù),規劃執行刀具的移動(dòng)軌跡,設定機床加工強度與速度參數。在云環(huán)境下自動(dòng)采集機床模擬量與位姿,根據當前機床運行參數與設定參數之間的偏差,利用PLC模擬量?jì)?yōu)化技術(shù)生成機床控制指令,實(shí)現機床的自動(dòng)控制功能。通過(guò)系統測試得出結論:綜合兩種實(shí)驗場(chǎng)景,與傳統控制系統相比,優(yōu)化設計系統在機床執行刀具位置、運行速度和執行應力三個(gè)方面的控制誤差分別降低約13.8mm、0.26mm/s和3.4N,同時(shí)機床的抖振現象得到明顯緩解。

    Abstract:

    With the aim of solving the problems of chattering and high control errors in the control process of machine tools, using PLC simulation optimization technology in a cloud environment, the automatic control system of machine tools is optimized and designed from both hardware and software aspects. Add Programmable logic controller, refit sensor, motor and driver, adjust the connection mode of system circuit, and complete the optimization of machine tool automatic control hardware system. According to the production task of the machine tool, plan and execute the movement trajectory of the cutting tool, and set the processing strength and speed parameters of the machine tool. Automatically collect machine tool simulation data and pose in a cloud environment. Based on the deviation between the current machine tool operating parameters and the set parameters, use PLC simulation optimization technology to generate machine tool control commands and achieve automatic control function of the machine tool. Through system testing, it is concluded that, compared with traditional control systems, the optimized design system reduces control errors in the three aspects of tool position, running speed, and execution stress of the machine tool by approximately 13.8mm, 0.26mm/s, and 3.4N, respectively. At the same time, the chattering phenomenon of the machine tool is significantly alleviated.
