Description
Technical field
The present invention relates to the machining field of workpiece, especially a kind of master form mechanism。
Background technology
Copying is with ready-made pattern for foundation, adds man-hour under certain pressure effect, and contact is in close contact with pattern working surface, and move along its surface, by feeler mechanism, cutter is made to do synchronized profile modeling action, thus processing the part of profile identical with pattern on part blank。Copying is one of the die cavity to various parts, particularly mould parts or the profile important method carrying out machining。Conventional copying has profile milling, copying planing and profile copy grinding etc.。
But copying has the disadvantage in that。It is often depending on the shape of its profiling mould for the machining shape of workpiece。And for the bigger workpiece of flexibility, owing to its amount of having changes greatly, the curvature of shape is relatively big, the profiling shape relying solely on pattern is the crudy being difficult to reach to need。
Summary of the invention
It is an object of the invention to provide the milling technology scheme of a kind of copying, it disclosure satisfy that the shape processing needs of workpiece that deep camber, bending change are bigger。
A kind of Milling Process assembly; for part fore-and-aft plane is milled into longitudinal curved surface; Milling Process assembly includes master form mechanism, milling cutter, milling cutter lengthwise rows walking apparatus and Der Laengslenker; milling cutter lengthwise rows walking apparatus is used for driving milling cutter along described Der Laengslenker lengthwise movement, and described milling cutter lengthwise rows walking apparatus also allows for milling cutter and does laterally opposed motion relative to milling cutter lengthwise rows walking apparatus and Der Laengslenker；Described master form mechanism is provided with processes profile contour first, reworking profile contour and pattern contoured fit walking mechanism, pattern contoured fit walking mechanism is used for being connected between cutter and master form mechanism, and including road wheel with the described contoured fit with master form mechanism, processing profile contour for controlling the first lateral feed of milling cutter when the first passage processing first, described reworking profile contour for controlling the residue lateral feed of milling cutter when the second passage processing, first lateral feed is total lateral feed with residue lateral feed sum, described total lateral feed can characterize the initial configuration of workpiece and the difference of final form；
Described processing profile contour first and reworking profile contour control to meet following formula for the lateral feed in axial workpiece milling process:
Smax=Sq·(1+E%)
Smin=Sq·(1-E%)
Wherein,
Z represents the total lateral feed in the process of axial workpiece milling；
Zmax represents total lateral feed maximum in the process of axial workpiece milling；
Zmin represents total lateral feed minimum in the process of axial workpiece milling；
Smax represents the residue lateral feed at total lateral feed maximum position place in the process of axial workpiece milling；
Smin represents the residue lateral feed at total lateral feed minimum position place in the process of axial workpiece milling；
Sq represents the expectation lateral feed of milling cutter during the second passage processing；
E% represents the floating deviation percent that milling cutter can accept under the benchmark of described expectation lateral feed Sq when the second passage processing；
S represents the residue lateral feed at general position place in the process in axial workpiece milling；
Described method comprises the steps:
A uses processing profile contour first that workpiece is carried out turnery processing first；
B changes milling cutter；
C uses reworking profile contour that workpiece is carried out turnery processing again。
By such scheme, process first with the first passage, the contour curve of milling workpiece is substantially processed；Processing for the very big deep camber workpiece of degree of crook, compared with the curve surface of workpiece profile " oriented parallel " (being described in detail below) formed during with two passage processing, the allowable deviation +/-E% of expectation amount of feeding time the solution of the present invention takes full advantage of for the second passage processing, the location of workpiece in the indent needing big cutting output, utilization+E%, namely, after first processing, the second passage processing undertakes more cutting output；And in protruding parts owing to total cutting output is less, it is contemplated that cut balanced and necessary cutting output to form surface accuracy, utilization-E%。In other positions, linear relationship is utilized to draw residue lateral feed；So, utilize the contour shape of two patterns, the lateral feed of two passages has been carried out reasonable distribution；Avoiding the second passage and be processed to form too much cutting output, it also avoid in the bigger position of total cutting output meanwhile, the first passage undertakes a large amount of cutting。So, improve the force-bearing situation of cutter, improve cutter life, simultaneously as the situation that processing capacity in curved profile is inconsistent has been carried out maximum balance, also improve the surface quality of workpiece simultaneously；By changing milling cutter, it is possible to meet the reworking two aspect requirements for contour shape and surface accuracy。
