Abstract
A method for realizing curved surface machining via a numerical control machine is characterized in that a standard model of a part with a curved surface, which needs to be machined, is mounted on the numerical control machine, a measuring head is mounted at a tool position, the size and the shape of the measuring head are completely identical to those of a rotator which is formed due to rotation of a cutting edge of a tool, the measuring head clings to the curved surface of the standard model, the numerical control machine drives the measuring head to acquire coordinate data of various points on the curved surface, and the coordinate data of the various points on the standard model are recorded via measuring software. The standard model and the measuring head are detached, a workpiece and the knife are respectively mounted, and the numerical control machine machines a curved surface of the workpiece by the tool according to the coordinate data of the various points, which are measured by the measuring head and recorded by the measuring software, so that the workpiece with the curved surface identical to that of the standard model can be obtained. The method is simple and convenient, is perfect in effect, and effectively reduces errors of a measuring machine, program conversion errors and machining errors of the numerical control machine in an existing machining process of parts with curved surfaces, and precision of the curved surfaces of machined parts is high.
Description
Technical field
The invention belongs to the mechanical manufacturing method class, specifically is a kind of method that realizes Machining of Curved Surface with numerically-controlled machine.
Background technology
In mechanical processing industry, have the part that much has complicated irregular curved surface to need processing, the processing of these parts often all has very high accuracy requirement, and material much all is a difficult-to-machine material; Like jet blade, turbine blade, marine propeller etc.; The curve form of these parts is difficult to describe with mathematical formulae, and it makes the general model of confirming earlier, on measuring machine, measures its curve form; Again measurement result is converted to be programmed on the corresponding numerically-controlled machine and process; Because have measuring machine error, program conversion error and Numerical Control Machine Tool Machining Error to exist, the surface machining accuracy of part does not often reach requirement, causes scrapping of product.
Summary of the invention
The objective of the invention is deficiency to prior art; A kind of method that realizes Machining of Curved Surface with numerically-controlled machine is provided; Effectively overcome measuring machine error, program conversion error, reduce Numerical Control Machine Tool Machining Error, surface accuracy simple and convenient, satisfactory for result, that process is high.
Technical scheme of the present invention is following:
A kind of method that realizes Machining of Curved Surface with numerically-controlled machine of the present invention; It is characterized in that: the master pattern of the part of the band curved surface that will process earlier is contained on the numerically-controlled machine; Measuring head is loaded onto in the tool position, and it is just the same that the cutting edge of the size of measuring head, shape and cutter rotates formed solid of revolution, and measuring head is close to the curved surface of master pattern; By the numerically-controlled machine drive coordinate data of each point on the curved surface is gathered, and note the coordinate data of the each point on the master pattern by Survey Software; Pull down master pattern and measuring head, load onto workpiece and cutter respectively, the coordinate data of the measuring head each point of being noted by Survey Software by numerically-controlled machine is processed curve surface of workpiece with cutter, can obtain the workpiece consistent with the master pattern curved surface.
The present invention because adopted cutting edge with cutter to rotate formed revolution shape, equirotal measuring head is gathered the coordinate data of master pattern curved surface each point; Directly workpiece is processed with cutter according to image data again; Obtain the workpiece consistent with the master pattern curved surface, the present invention is simple and convenient, and is satisfactory for result; Effectively reduced measuring machine error, program conversion error and Numerical Control Machine Tool Machining Error in the existing curved surface part processing, the part surface accuracy of processing is high.
Embodiment
The concrete job operation of the present invention is: the master pattern of the part of the band curved surface that will process is contained on the machining tool, and measuring head is loaded onto in the tool position, and it is in full accord that the size of measuring head, shape and Tool in Cutting sword rotate formed solid of revolution; Selected two axles are motorized shaft, and all the other axles are driven shaft, remove the gear train on the driven shaft; The moving guide rail of linear axis can be moved freely, and turning axle can rotate freely, and measuring head is applied a strength; Make on its curved surface that is close to tested master pattern, in the measuring process, select first to be fixed on a certain position in two motorized shaft; Second motion, grating on the driven shaft or scrambler reflect the relevant position of driven shaft, the coordinate data of each point when being fixed on a certain position by first of the Survey Software of digital control system record; Again first mobile equaling cut the distance of spacing and fix, first coordinate data and record at second locational each point measured in second motion; Continue to move first, till the coordinate data of whole each point is all gathered, because that the measuring head shape of image data, size and Tool in Cutting sword rotate formed solid of revolution is in full accord; After the coordinate data collection of each point, do not need any conversion,, measuring head is removed as long as confirm that process velocity can make measurement data directly change job sequence into; And load onto cutter, and the gear train of all driven shafts is reinstalled, load onto workpiece to be processed; By digital control system cutter is processed by measuring sequence to workpiece, obtained the workpiece consistent with master pattern.
Numerically-controlled machine of the present invention must be the control of full cut-off ring.
