我们知道,要自动化加工出一个机械零件,可通过数控、程控或仿形来实现。但数控需要先编程,而仿形则要先做一个样板,都较费事。而今,机床有了一种新的叫做“录返”的功能——Playback,只要让有经验的老师傅先操作一遍,机床就能自动地记录下运行的轨迹,以后那怕让刚进厂的学徒也能加工出原件一模一样的零件来。最近,上海第四机床厂生产的XTK 754数控铣镗床,由于配备了日本FANUC——3M数控箱,就具有这种录返功能。录返功能类似于机器人技术中的示教再现功能。通俗地讲,只要人们先示范一遍,机床就可学会人们所示教的动作。当要作录返操作时,先把机床面板上 We know that we need to automate the machining of a mechanical part that can be controlled by CNC, programmed or contoured. However, NC needs to be programmed first, and profiling is to be a model first, all of which are troublesome. Today, the machine has a new feature called “recordback” - Playback, as long as the experienced teacher to operate it again first, the machine can automatically record the running track, even after just let the factory just entered Apprentices can also produce the same original parts to the original. Recently, XTK 754 CNC boring and milling machine produced by Shanghai No.4 Machine Tool Plant owns such function of recording and returning as equipped with Japan FANUC - 3M numerical control box. The recordback function is similar to the teach-in reproduction function in robot technology. Generally speaking, as long as people demonstrate it first, the machine can learn what people teach. When you want to make a return operation, the first machine panel
