Abstract

The invention relates to the technical field of the machining of an aluminum alloy sectional material, and particularly relates to an improved aluminum alloy sectional material cutting machining method. When the aluminum alloy sectional material is milled, under the situation that the metal removal rate is constant, a smaller axial cutting depth and a greater radial cutting depth are better than a greater axial cutting depth and a smaller radial cutting depth. By adopting the improved aluminum alloy sectional material cutting machining method, on the premise of meeting the machining requirement and satisfying the conditions of a machine tool and a cutter, the feed amount and the cutting area can be further increased, so that a purpose of improving the cutting machining efficiency can be achieved.

beneficial effect of the present invention:
The cutting working method of the aluminium alloy extrusions of improvement of the present invention, during milling aluminium alloy extrusions, when metal removal rate is constant, the axial cutting-in of selection of small and larger radial cutting-in ratio select larger axis to cutting-in and less radial cutting-in advantageously.During high-speed milling aluminium alloy extrusions, the axial cutting-in of selection of small not only significantly can reduce cutting force, and better suface processing quality can be obtained, from when reducing the angle Selection cutting data of cutting deformation, select larger radial cutting-in not only can reduce cutting force, and workpiece rigidity can be increased.From cutting test data, method of the present invention, under the prerequisite meeting processing request and lathe, cutter conditions permit, also can increase the amount of feeding and the area of cut further, to reach the object improving machining efficiency.
Detailed description of the invention
The invention will be further described with the following Examples.
The cutting working method of the aluminium alloy extrusions of improvement of the present invention, comprises the following steps:
1) this aluminium alloy extrusions is positioned on the workbench of machining tool, milling cutter feeding device controls this milling cutter and to rotate and against the side-wall outer side of this aluminium alloy extrusions, described milling cutter feeding device includes cutter, described milling cutter feeding device this workbench relative along preset path translation, and controls the amount of feeding of the relative aluminium alloy extrusions of described cutter;
2) orthogonal experimental design method is adopted, measure cutter string milling temperature signal, Milling Force signal and milling vibration signal under milling usage parameters combination, and from described string milling temperature signal, Milling Force signal and milling vibration signal, select corresponding signal maximum as the numerical value of Milling Temperature, Milling Force and the milling vibration under default milling usage parameters combination;
3) with minimum cost per unit for object function, using cutter life as constraint function, by lathe rotating speed, radial cutting-in, axially cut wide with feed speed or feed engagement in conjunction with laggard line parameter optimization, obtain the best milling usage parameters combination of cutter;

Concrete, tool selection f10mm ultrafine gain size solid end mill, corner radius is 1.5mm.
Measurement result shows, the surface roughness Ra value of test specimen corner, a little more than the Ra value at test specimen straight flange place, has occurred oblique chatter mark in test specimen corner during upmilling; But as Ra=0.5mm, the Ra value of test specimen corner is less than the Ra value at straight flange place on the contrary, this can produce certain influence to machined surface roughness because thickness of cutting changes the Milling Force fluctuation caused, when axial cutting-in is less, along with the reduction of Milling Force, Milling Force fluctuation also reduces the impact of machined surface roughness thereupon, therefore, along with the reduction of axial cutting-in, surface roughness Ra value is on a declining curve.When adopting that comparatively large inflow ap carries out Milling Process, there is the chatter mark perpendicular to direction of feed in workpiece straight flange place, but the impact of effects on surface roughness Ra is little.
During high-speed milling aluminum alloy materials, when metal removal rate is constant, the axial cutting-in of selection of small and larger radial cutting-in ratio select larger axis to cutting-in and less radial cutting-in advantageously.During high-speed milling aluminum alloy materials, the axial cutting-in of selection of small not only significantly can reduce cutting force, and can obtain better suface processing quality.From when reducing the angle Selection cutting data of cutting deformation, select larger radial cutting-in not only can reduce cutting force, and workpiece rigidity can be increased.From cutting test data, the method for invention, under the prerequisite meeting processing request and lathe, cutter conditions permit, also can increase the amount of feeding and the area of cut, further to reach the object improving machining efficiency.
