Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of method that machining code speed of feed ensures that lathe output power is level and smooth of adjusting.
Background technology
In the NC Machining Process of aircraft structure, need to keep machine tool chief axis output power relatively level and smooth, the safety of guarantee cutting system.But in given job sequence, cutting speed of feed is relatively-stationary, in the time that the material removal amount of cutter moment cutting changes, likely cause the output power of machine tool chief axis extremely unstable because speed of feed is constant, serious impact lathe and cutter steadily, affect serviceable life.
Machine tool chief axis power and the speed of mainshaft, speed of feed, material removal coefficient, cutting-in, cut the parameter correlations such as wide, how, in these parameters, rationally adjust a few parameters wherein, meet machine power and smoothly export requirement, just seem very important.Obviously, in working angles, the speed of mainshaft, material removal coefficient can not arbitrarily change, and can only and cut wide adjustment speed of feed according to current cutting-in.
Machining simulation can be simulated the process of actual parts on computers, the correctness of checking numerical control program, the trial cut work of replacement of parts, can shorten cycle that manufactures and designs of part, being of great practical significance, is also the inexorable trend of Developing Trends of Modern Manufacturing Technology.Current some machining simulation class softwares that use, mostly can only reflect the process of Tool in Cutting part part, user can not set up the lathe and the cutter model that are applicable to self-condition, the simulated environment can only passive Selection Software providing, thereby can not reach nc machining simulation and virtual completely.
VERICUT software is the numerical control machining simulation system of CGTECH company of U.S. exploitation, by NC (Numerical Control, digital control, be called for short numerical control) the module composition such as code verification module, machine tool motion emulation module, path optimizing module, multiaxis module, senior lathe characteristic module, entity comparison module and CAD/CAM interface, can emulation numerically controlled lathe, the NC Machining Process of the various processing equipment such as milling machine, machining center, wire cutting machine tool and gang tool, also can carry out NC code optimization.Can set up complete Virtual Machine by VERICUT software, not only simulated effect is more true to nature, and can realize the virtual manufacture of overall process.Therefore, in actual NC Machining Process, can combining with digital control system, numerical control program, obtain current cutting parameter by the cutting of VERICUT software simulation, material cutting-in and cut parameter and the limiting factor (s)s such as wide in reference power, material removal coefficient, feed engagement and the process of selecting with reference to machine power, user, optimize the speed of feed in NC code, reach the object of level and smooth main shaft output power, and then improve the security of lathe, cutter and workpiece.
But in practical use, while ensureing that by adjusting machining code speed of feed lathe output power is level and smooth, have some to wait the problem solving:
(1) data relationship between various cutting parameters does not have ready-made available formula.

(2) machine power can not directly measure, and is difficult for adjusting in actual production
Machine tool chief axis power and the speed of mainshaft, speed of feed, material removal coefficient, cutting-in, cut the parameter correlations such as wide, can not be by measuring.Therefore,, by the combined influence factor of the numerous parameters of research, rationally adjust a few parameters wherein, can smoothly export to meet machine tool chief axis power.Consider in addition that, in working angles, the speed of mainshaft, material removal coefficient can not arbitrarily change, and how to adjust machining code simultaneously, finally realize smoothly still having of machine tool chief axis output power to be solved.
(3) VERICUT software does not possess the copying of cutting force
VERICUT software geometric simulation functional efficiency is very high, can within even tens of seconds of a few minutes, complete the geometric simulation of complex parts process, but it does not have cutting forces simulation function.Therefore be necessary it to carry out secondary development, program be embedded into VERICUT software, after geometric simulation completes, extract whole process cutting-in, cut the parameters such as wide, speed of feed, cutting speed, and can provide intuitively cutting power.
