The open type intelligent milling system disclosed by the invention comprises a three-way piezoelectric type dynamometer sensor, an A/D (Analogue/Digital) conversion circuit, an industrial PC (Personal Computer), a PCI (Peripheral Component Interconnect) data acquisition card, a milling controller, an Soft SERCANS communication card, an input/output module and n servo drivers. The milling method disclosed by the invention comprises the following steps of: acquiring a cutting force generated by interaction between a work-piece and a cutter in real time; obtaining a feeding multiplying power by the milling controller so as toobtain a new feeding speed as the next feeding speed of the cutter; determining a next position of a machine tool; transmitting a position instruction to the corresponding servo drivers by the milling controller through the Soft SERCANS communication card and the input/output module so as to control the corresponding cutters to move; and realizing the intelligent control of the processing.

Description

technical field [0001] The invention relates to an open intelligent milling processing system and a milling processing method based on the system, belonging to the field of mechanical processing. Background technique [0002] Realizing the automation and intelligence of the processing process has always been the two main goals of the development of modern manufacturing technology. In the traditional metal cutting process, in order to prevent the overload of the machine tool and protect the tool, as well as eliminate the influence of various uncertain factors, the cutting amount is often determined by checking the relevant mechanical processing manual and empirically. It is often only allowed to set key parameters (such as feed speed, spindle speed, etc.) once. This results in longer machining times, deformation of the tool due to fluctuations in cutting force, premature tool wear due to cutting load, and reduced workpiece machining quality. At present, in order to improve ...
