Below be the principle that example further specifies lathe crawl control system of the present invention with the five-axis linkage machine tools, it is understandable that the present invention not only can be used for five-axis linkage machine tools, also can be applied to four, three even diaxon lathe.
Said five are meant at three linear drives axle X of lathe three dimensions definition, Y, Z with around rotating driveshaft A, the B of wherein two linear drives axle rotations; Usually five-axle linkage is meant the linear interpolation motion of X, Y, Z, A, B, 5 driving shafts; The motion of each driving shaft can be by worktable; Also can realize, and drive by corresponding servomotor by the motion of cutter.
At first set mapping relations, as shown in Figure 4.When to X+ direction slide head 1, expression control X spindle motor positive movement; When X-direction slide head 1, the negative movement of expression control X spindle motor; When Y+ direction slide head 1, expression control y-axis motor positive movement; When Y-direction slide head 1, the negative movement of expression control y-axis motor; Along Z+ direction pull operation 1 o'clock, expression control Z spindle motor positive movement; When the Z-direction is pressed operating head 1, the negative movement of expression control Z spindle motor; To X-and Y+ third side during to slide head 1, expression control A spindle motor positive movement; To X+ and Y-third side during to slide head 1, the negative movement of expression control A spindle motor; To X+ and Y+ third side during to slide head 1, expression control B spindle motor positive movement; To X-and Y-third side during to slide head 1, the negative movement of expression control B spindle motor.Can realize JOG (crawl) motion of the single shaft forward or the negative sense of X, Y, Z, A, five axles of B like this.
But because the direction that moves of operating head 1 is arbitrarily, generally when with hand propelled operating head 1, specified direction does not overlap in the sense of displacement that is produced and the above-mentioned mapping relations, but certain deviation is arranged, and departure is a random variation.Therefore, for fear of the misoperation of lathe, must calibrate the displacement that is produced.As can be seen from Figure 5, under the single shaft drive pattern, for the responding range that guarantees each driving shaft not overlapping; The misalignment angle value that allows need be less than ± 22.5 degree, but in practical operation, can select to be set to-10 °～10 ° scope; When deviation greater than this scope in the time, promptly be regarded as this action not in the control area of this driving shaft, system will not respond; If certain driving shaft there is this moment in motion, then slow down, stop up to this axle.
Under the single shaft drive pattern, when the mode of control machine tool chief axis crawl is continuous mode:
Suppose that the displacement that operating head 1 slides within a certain period of time is R, anti-predetermined value of trembling in the module 221 is R
Min, then
Wherein, x, y and z are respectively first slide plate 31, second slide plate 32 and the 3rd slide plate 33 according to coordinate figure that self-position produced.If the ultimate range that operating head 1 all directions can be slided is R
Max, can set the linear and maximum slip amplitude R of amplitude that JOG speed and operating head 1 slide here

Operating head 1 is not in the control angular range of any one, if current have driving shaft in motion, then slows down.
Operating head 1 is in control limit displacement R
MinIn, if current have driving shaft in motion, then slow down.
When the mode of control machine tool chief axis crawl was single-step mode, preset rules was similar with continuous mode, and difference is that when operating head 1 drops in the control zone distance of the Control Shaft mode initialization of single step JOG that this direction is corresponding is just no longer mobile.Only when operating head 1 had left the control area and slipped into the control area once more, corresponding driving shaft just can respond once more.Single-step mode is mainly used in the accurate location of each.
Under the twin shaft drive pattern:
Under the twin shaft drive pattern, can only there be two axles to move simultaneously at most in X, Y, three driving shafts of Z.Not hoping the 3rd axle at an in-plane moving when the main shaft of hoping lathe has when mobile, can use this pattern.
With X, the motion in the plane that the Y axle is formed is an example.If current operating head 1 coordinate points of living in be (x, y, z),
Still set certain direction coordinate figure and surpass a boundary value R
MinThe time driving shaft just make a response, the ultimate range that operating head 1 all directions can be slided is R
Max, set the linear and maximum slip amplitude R of amplitude that JOG speed and operating head 1 slide

x=V*x/R1; Y direction speed V

Under three drive patterns:
Under the three-axis moving pattern, X, Y, three driving shafts of Z can carry out the JOG motion simultaneously.When the main shaft of hoping lathe moves to certain Position Approximate in the space, can use this pattern to realize the quick JOG motion of main shaft.
If current operating head 1 coordinate points of living in be (x, y, z),
Still set certain direction coordinate figure and surpass a predetermined value R
MinThe time driving shaft just make a response, the ultimate range that operating head 1 all directions can be slided is R

Should be noted that and to change to different requirement, so so long as can realize above-mentioned JOG function, promptly should be regarded as the covering scope of preset rules according to the invention.In addition, above-mentioned preset rules also can comprise controls four, the JOG of five-axle linkage motion simultaneously, and its principle is similar with three-shaft linkage, repeats no more at this.
In sum, the lathe crawl control system of present embodiment adopts above-mentioned implementation, not only can realize the JOG control of machine tool chief axis simply and easily, and can control a plurality of driving shafts simultaneously, reaches the effect of fast moving main shaft to the target location.Simultaneously, the speed regulation of JOG motion is very convenient, and the amplitude that only needs to regulate operating head 1 just can change the JOG speed of main shaft, not only fast but also directly perceived.

In the said method, further comprising the steps of behind step S42:
S43: under the single shaft drive pattern, if specified direction does not overlap in the direction of this displacement and the said mapping relations, then the deflection with this displacement adds a modified value, makes it satisfy said mapping relations.
Below adopt the control member 1 described in the embodiment one to implement this method with control assembly 2, and the action details of each step of further explain.The structure and the principle of control member 1 and control assembly 2 are seen embodiment one, repeat no more here.Suppose to be that machine coordinates point (X, Y, Z) is located to the target location with main shaft JOG in advance, below specify its implementation, above-mentioned lathe is an example with the three-shaft linkage lathe.
At first, chosen axis pattern.When having only one among coordinate figure X, Y, the Z when non-vanishing, an axle model selection is the single shaft drive pattern; When having two among coordinate figure X, Y, the Z when non-vanishing, an axle model selection is the twin shaft linkage pattern; When having among coordinate figure X, Y, the Z when all non-vanishing, an axle model selection is the three-shaft linkage pattern.
One, under the single shaft drive pattern.
1, the crawl pattern is a continuous mode.At this moment, driving shaft will drive near the machine tool chief axis continuous motion target location, can only be as the coarse localization of main shaft.
Under the single shaft drive pattern, the driving shaft that non-vanishing coordinate figure is corresponding among X, Y, the Z be the driving shaft that needs control under this pattern, and for example, X is non-vanishing, and then the single shaft drive pattern only need be controlled lathe X axle and moves and get final product.How control operation 1 slip just can make main axle moving be only key to the target location.Preset rules in the control assembly 2 is provided with the relation between the speed that amplitude that operating head 1 slides and main shaft JOG move: suppose that operating head 1 slidable amplitude peak is R
Max, the predetermined value of setting among the step S41 is R
Min, the linear and maximum slip amplitude R of amplitude that main shaft JOG speed and operating head 1 slide
MaxCorresponding maximum JOG speed is V
MaxTherefore, the displacement of control operation 1 slip or the speed that amplitude has promptly been controlled main shaft JOG.According to mapping relations shown in Figure 4; Integrating step S43; Suppose that the sense of displacement that operating head 1 moves departs from the X axle (at this moment; Can be X+ axle or X-axle according to the positive negative judgement of the coordinate figure X in the target location) angle be θ, then, make it satisfy above-mentioned mapping relations with θ angle of this sense of displacement correction.If this moment, the coordinate figure of first slide plate 31 was x, then can obtain actual JOG speed V=(x-R
