Abstract
The present invention relates to a kind of method that sponge cutting machine graphics processing line segment Auto-Smooth connects, described step is: first, utilize the relation of trigonometric function, compile process order in software, finish in graphics processing, judge the tangential angle becoming between these wedge angles processing more front and rear; Secondly, sponge cutting machine, in cutting process, when these wedge angle angles are within these scopes, first judges whether next corner needs smooth; If the judgment is Yes, while arriving corner, sponge cutting machine is not done retarded motion, calculates corner sequence by tarnsition velocity, is added in proper motion control sequence, and motion limit, corner axle limit turns; If the judgment is No, while arriving corner, sponge cutting machine is done retarded motion, corner, and starting is cut again. The invention has the advantages that: machine carries out automatically gyration in advance according to current linear velocity, go on along track, be exactly to have walked one section of very little circular arc so in fact, and very smooth cutting is gone down.
Description
Technical field
The present invention relates to a kind of method that sponge cutting machine graphics processing line segment Auto-Smooth connects.
Background technology
In the time of today's numerical control sponge cutting machine cutting sponge product, we, with reference to model mapping matching, draw like thisThe figure getting off has the feature of these figure below. Schematic diagram is as shown in Figure 1, Figure 2 and Figure 3 known, and these figure circles indicateThere is the wedge angle flex point 1,2,3 of these features at position, and this goes to these flex points and all can pause one in the time that machine cuts these figuresUnder, after cutter turns to this angle by the time, cutting again, the product of the place cutting simultaneously pausing has cutter and printsTrace, the presentation quality of the product of not only having lost time but also affected. For this phenomenon, if manually remove to revise figure, will increaseVery large workload.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of sponge cutting machine that can automatically revise as required figureThe method that graphics processing line segment Auto-Smooth connects.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of sponge cutting machine graphics processing line segment certainlyThe moving method being smoothly connected, its innovative point is: described step is:
A) first, utilize the relation of trigonometric function, in software, enroll program, wait to have the graphics processing picture of multiple wedge anglesAfter good, judge the tangential angle becoming between these wedge angles processing more front and rear;
B) secondly, sponge cutting machine is in cutting process, and whether the tangential angle of determining step described in a) be at 10 °-40 °Between, thereby it is smooth to judge whether next corner needs;
If c) be judged as YES in step b, while arriving corner, sponge cutting machine is not done retarded motion, by tarnsition velocityCalculate corner sequence, be added in proper motion control sequence, motion limit, corner axle limit turns;
If d) be judged as NO in step b, while arriving corner, sponge cutting machine is done retarded motion, corner, again startingCut.
The invention has the advantages that: machine is in cutting process, and when these wedge angle angles are within 10 °-40 °, machine existsWhile walking these lines, carry out automatically gyration in advance according to current linear velocity, go on along track, be exactly so in fact simultaneouslyWalk one section of very little circular arc, very smooth cutting is gone down, no longer included the phenomenon of the gyrations such as pause.
Brief description of the drawings
Fig. 1 is the schematic diagram that utilizes the first sponge flex point that existing program cuts out.
Fig. 2 is the schematic diagram that utilizes the second sponge flex point that existing program cuts out.
Fig. 3 is the schematic diagram that utilizes the third sponge flex point that existing program cuts out.
Detailed description of the invention
The method that sponge cutting machine graphics processing line segment Auto-Smooth of the present invention connects, its step is specific as follows:
The first step, first, utilizes the relation of trigonometric function, enrolls program in software, waits to have the processing of multiple wedge anglesAfter figure is finished, judge the tangential angle becoming between these wedge angles processing more front and rear.
Second step, secondly, sponge cutting machine is in cutting process, and whether the tangential angle of determining step described in a) existsBetween 10 °-40 °, thereby it is smooth to judge whether next corner needs.
The 3rd step, if be judged as YES in second step, while arriving corner, sponge cutting machine is not done retarded motion, by turningAngular speed calculation corner sequence, is added in proper motion control sequence, and motion limit, corner axle limit turns.
The 4th step, if be judged as NO in second step, while arriving corner, sponge cutting machine is done retarded motion, corner is heavyNew starting is cut.
More than show and described general principle of the present invention and principal character and advantage of the present invention. The technology of the industryPersonnel should understand, and the present invention is not restricted to the described embodiments, and the just explanation of describing in above-described embodiment and description originallyThe principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these changesChange and improve and all fall in the claimed scope of the invention. The claimed scope of the present invention by appending claims andEquivalent defines.
Claims (1)
1. the method that sponge cutting machine graphics processing line segment Auto-Smooth connects, is characterized in that: described step is:
