Abstract
The invention discloses a workpiece processing method for a numerically controlled lathe. The processing method comprises the following steps of: (1) dividing workpieces to be finished in one process step into over two processing sections along a workpiece feeding direction; (2) performing numerically controlled programming on a feeding path of a cutter in the step (1) through a numerically controlled system; and (3) performing numerically controlled processing on the processing sections in the step (1) at the same time. The workpiece processing method for the numerically controlled lathe can shorten the processing period during processing the long-axis workpieces and reduce the stroke of the cutter, and has incomparable efficiency compared with a common lathe; and the method for determining the feeding path of the cutter in the invention is simple, and reduces the programming difficulty of the numerically controlled lathe.
Description
Technical field
The present invention relates to numerically-controlled machine, relate in particular to numerically controlled lathe.
Background technology
Numerically controlled lathe is called the CNC lathe again, it is the computer numerical control (CNC) lathe, have various machining functions such as linear interpolation, circular interpolation, and in the batch process of complex part, brought into play good economic effect, it is present domestic use amount maximum, a kind of numerically-controlled machine that coverage rate is the widest accounts for 25% of numerically-controlled machine sum.Present universal numerical control lathe is adding man-hour, has only a cutter carrying out cutting, and it is long to have the process-cycle when processing major axis type workpiece, and the cutting stroke of cutter on the Z direction such as grows at shortcoming.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of Work piece processing method of numerically controlled lathe, when processing major axis type workpiece, can shorten the process-cycle, reduce the workpiece stroke.
Technical scheme: for achieving the above object, the technical solution used in the present invention is:
A kind of Work piece processing method of numerically controlled lathe comprises the steps:
(1) workpiece that need finish in a work step is that Z-direction is divided into n processing sections, i.e. Z along the workpiece direction of feed
1, Z
2Z
n, n 〉=2 wherein, preferred n=3;
(2) by digital control system the feed path of cutter in the step (1) is carried out numerical control programming;
(3) processing sections in the step (1) is carried out digital control processing simultaneously.
A work step is meant on same station, in the time of finishing different surface working, and wherein under the situation that finished surface, cutting speed, the amount of feeding and machining tool are all constant, a part of station content of that finished continuously.
Each processing sections uses respectively corresponding to the cutter of processing sections separately and processes simultaneously in the described step (2), corresponding to processing sections Z
1Use cutter T
1, cutter T
1Feed path be X
1Corresponding to processing sections Z
2Use cutter T
2, cutter T
2Feed path be X
2, by that analogy.
Each cutter is installed on the planker of a plurality of parallel X-axis, and the planker of all parallel X-axis is installed on the Z axle saddle, and just lathe requires to possess a plurality of X-axis, a Z axle.
The feed path of cutter is determined as follows in the described step (2):
(1) determine the machining profile of described workpiece, the feed profile of cutter, choosing the workpiece direction of feed is that Z is axial, with Z axle vertical direction be X axis;
(2) choose any one cutter for reference to cutter, be defined as workpiece coordinate system, the feed profile of other cutters is axially gone up along Z and is offset forward or backwards to the reference cutter, and the distance of skew is exactly current cutter and distance with reference to cutter;
(3) determine that the skew back is along the axial coordinate position of each cutter profile on feed profile variations point of Z, i.e. skew back X
1, X
2X
nCoordinate with Z;
(4) according to skew back X
1, X
2X
nProgramme with the coordinate of Z, program path is along Z axle cutting direction.
Beneficial effect: the Work piece processing method of numerically controlled lathe provided by the invention, when processing major axis type workpiece, the process-cycle can be shortened, reduce the workpiece stroke, the incomparable efficient of general lathe is arranged, and definite method of cutter path provides theoretical foundation for the programming software of the workpiece processing of establishment the type during programming provided by the invention.
Description of drawings
Figure 1 shows that workpiece segmental machining synoptic diagram provided by the invention;
Figure 2 shows that cutter operating path graph of a relation among the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is further illustrated.
Be illustrated in figure 1 as the method synoptic diagram of numerically controlled lathe workpiece processing provided by the invention, workpiece to be machined length is 500mm, and numerically controlled lathe adopts three parallel cutter T

3Feed path determine as follows:
(1) by the machining profile of definite workpiece to be machined shown in Figure 1, the feed profile of cutter, choosing the workpiece direction of feed is that Z is axial, with Z axle vertical direction be X axis;
(2) choose cutter T
3Be the reference cutter, with cutter T
1And T
2The feed profile along on the Z axle to cutter T
3Direction skew 310mm and 160mm determine workpiece coordinate system, and dimensioning as shown in Figure 2;
(3) determine that the skew back is along the axial coordinate of each cutter profile on feed profile variations point of Z, i.e. skew back X
