Control instruction unit 35 is numerical control device (NC:Numerical Control), and the NC data 101B based on being generated by NC data generating unit 34 controls processing device 40.Control instruction unit 35 will be used to control the control indication information of processing device 40 to processing device 40 transmissions.The control instruction unit 35 of present embodiment is for example based on the translational speed d in the NC data 101B, and the indication of translational speed d that will be used to control the processing head 9 at each indication point place sends to processing device 40.
Below, the processing corners of the mouth degree θ at each the indication point place that sets in NC data 101A and NC data 101B is described.Fig. 5 is the figure that is used to illustrate the processing corners of the mouth degree of setting in each indication point place.In NC data 101A, 101B, as the position of processing head 9 and set for example indication point P1～P4.This indication point P1～P4 is corresponding with Working position on the workpiece W.
The workpiece W at indication point P1 place has the parallel plane shape with XY, and the workpiece W at indication point P3 place has the parallel plane shape with YZ.In addition, the workpiece W at indication point P2 place has the shape with XY plane and YZ plane angle at 45.In addition, the workpiece W at indication point P4 place has the parallel plane shape with XY.At indication point P1, P2 place, set the processing corners of the mouth degree θ (0 °) of the surperficial approximate vertical of the direction make processing mouth 10 and workpiece W.
But, according to the Working position difference, sometimes for fear of the collision between processing head 9 and the workpiece W, make perpendicular to the normal to a surface vector N of workpiece W and the angle of stipulating from formation between the laser ejaculation direction (processing mouth direction M) of processing mouth 10 (greater than 0 ° processing corners of the mouth degree θ).For example near indication point P3, be made as 0 ° if will process corners of the mouth degree θ, then processing head 9 contacts with workpiece W.Specifically, be made as 0 ° (first type surface of workpiece W is 90 ° with the angle that processing mouth 10 forms) if near indication point P3, will process corners of the mouth degree θ, then add man-hour at indication point P3 place, the surface of the work w1 that is set with the workpiece W of indication point P4 contacts with processing head 9.
Fig. 6 is the figure that is used to illustrate the processing corners of the mouth degree corresponding with the workpiece shape.In Fig. 6, the shape of the workpiece W of indication point P3 near and the position of processing head 9 are shown.As shown in the drawing, near the Working position w2 place the indication point P3 is being added man-hour, be made as 0 ° if will process corners of the mouth degree θ, then at Working position w2 place, the front end of processing mouth 10 is vertical with the YZ plane.Thus, attitude axle 16 contacts with surface of the work w1.Therefore, in NC data 101A, 101B,, processing corners of the mouth degree θ is set at the angle (angle that processing head 9 is not interfered with workpiece W) of regulation at indication point P3.
In addition, as according to shown in the explanation of Fig. 4,, be that 0 ° situation is compared then with processing corners of the mouth degree θ if processing head 9 is set the processing corners of the mouth degree θ of θ＞0 °, the thickness of slab of the workpiece W that processes correspondingly increases with the amount of processing head 9 inclinations.Under the situation that the processing corners of the mouth degree θ with θ＞0 ° processes workpiece W, if utilize with the identical translational speed of translational speed under the situation of the processing corners of the mouth degree θ processing work W of θ=0 °, processing head 9 is moved, then cause processing bad sometimes.Therefore, in the present embodiment, set the translational speed d (with respect to the amount of deceleration of datum velocity) of processing head 9 accordingly with processing corners of the mouth degree θ.In addition, sometimes indication points such as indication point P1～P4 are called indication point Px below.
Below, the motion flow of the laser-processing system that embodiment is related is described.Fig. 7 is the process flow diagram of the motion flow of expression laser-processing system.In CAD/CAM 20, the indication information that the designer will be used to set workpiece W shape via input part 21 to 27 inputs of workpiece shaped design portion.Workpiece shaped design portion 27 is according to the indication information of being imported, and the shape of design workpiece W sends the workpiece shape information a that designs to workpiece shape information storage part 22.Workpiece shape information storage part 22 storage workpiece shape information a.
Processing head positional information calculation portion 23 is based on the workpiece shape information a in the workpiece shape information storage part 22, calculate with Laser Processing in the relevant processing head positional information b (step S10) in position of processing head 9.Processing head positional information calculation portion 23 sends the processing head positional information b that calculates to processing corners of the mouth degree calculating part 24 and NC data generating unit 25.
Processing corners of the mouth degree calculating part 24 calculates the processing corners of the mouth degree θ (step S20) at each indication point Px place based on the workpiece shape information a in the workpiece shape information storage part 22 with by the processing head positional information b that processing head positional information calculation portion 23 calculates.Processing corners of the mouth degree calculating part 24 will be processed corners of the mouth degree θ and send to NC data generating unit 25.
NC data generating unit 25 generates the NC data 101A (step S30) with processing corners of the mouth degree θ based on from the processing corners of the mouth degree θ of processing corners of the mouth degree calculating part 24 and the processing head positional information b that is calculated by processing head positional information calculation portion 23.NC data generating unit 25 sends the NC data 101A that is generated to efferent 26.Efferent 26 will be sent to Working control device 30 by the NC data 101A that NC data generating unit 25 generates.
The NC data 101A that sends to Working control device 30 from the efferent 26 of CAD/CAM 20, via input part 31 to translational speed configuration part 33 and 34 inputs of NC data generating unit.
The translational speed d of the processing head 9 at each indication point Px place is set based on from the NC data 101A of input part 31 and the angle/speed corresponding informance 102 in angle/speed corresponding informance storage part 32 in translational speed configuration part 33.Angle/speed corresponding informance 102 is described here.
Fig. 8 is the figure of an example of expression angle/speed corresponding informance.In angle/speed corresponding informance 102, processing corners of the mouth degree θ is associated with the translational speed d of processing head 9.For example, 0 °≤θ＜30 ° are associated with 100% (reference value) of translational speed d, and 30 °≤θ＜60 ° are associated with 60% of translational speed d, and 60 °≤θ＜90 ° are associated with 30% of translational speed d.Being that the rate of deceleration is 0% under 100% the situation at translational speed d, is that the rate of deceleration is 40% under 60% the situation at translational speed d, is that the rate of deceleration is 70% under 30% the situation at translational speed d.
The processing corners of the mouth degree θ of each indication point is extracted in translational speed configuration part 33 in NC data 101A, and extracts the translational speed d that processes the corresponding processing head 9 of corners of the mouth degree θ in angle/speed corresponding informance 102 with each.For example, be under 45 ° the situation at processing corners of the mouth degree θ, translational speed configuration part 33 extract in angle/speed corresponding informance 102 60% as and θ=45 ° corresponding translational speed d, this 60% is set at translational speed d (step S40).Translational speed configuration part 33 sends the translational speed d that sets to NC data generating unit 34.
NC data generating unit 34 generates NC data 101B based on from the NC data 101A of input part 31 and the translational speed d that is calculated by translational speed configuration part 33.NC data generating unit 34 is set by the translational speed d to each the indication point Px place among the NC data 101A, thereby generates NC data 101B.For example, NC data generating unit 34 generates translational speed d with indication point P3 place and is made as 60% NC data 101B (step S50).NC data generating unit 34 sends the NC data 101B that generates to control instruction unit 35.
The structure of NC data 101A, 101B here, is described.Fig. 9 is the figure of the structure example of expression NC data.In Fig. 9, the epimere side is represented NC data 101A, and the hypomere side is represented NC data 101B.NC data 101A contains the processing corners of the mouth degree θ at the processing head positional information b at each indication point Px place and each indication point Px place and constitutes.In addition, NC data 101B contains the translational speed d at the processing corners of the mouth degree θ at processing head positional information b, each indication point Px place at each indication point Px place and each indication point Px place and constitutes.In other words, NC data 101B is the structure of the translational speed d at additional each indication point Px place in NC data 101A.
In laser-processing system, set translational speed d at each indication point Px after, carry out the examination processing of workpiece W, if examination processing is no problem, then carry out the volume production processing of workpiece W.Try processing or volume production add man-hour, control instruction unit 35 is based on the NC data 101B that is generated by NC data generating unit 34, the control indication information that will be used to control processing device 40 is controlled processing device 40 thus to processing device 40 transmissions.
Processing device 40 carries out Laser Processing (step S60) according to the control indication information that sends from the control instruction unit 35 of Working control device 30 to workpiece W.The processing device 40 of present embodiment, at each indication point Px place, the control indication information according to from control instruction unit 35 makes processing head 9 move with translational speed d.
In addition, in the present embodiment, be illustrated at the situation of NC data generating unit 25, but NC data generating unit 25 also can generate NC data 101A based on workpiece shape information a and processing corners of the mouth degree θ based on processing head positional information b and processing corners of the mouth degree θ generation NC data 101A.
In addition, in the present embodiment, situation at CAD/CAM 20 additional processing corners of the mouth degree θ in NC data 101A is illustrated, but CAD/CAM 20 also can replace processing corners of the mouth degree θ, and the workpiece W normal to a surface vector N at each indication point Px place is attached among the NC data 101A.In the case, the translational speed configuration part 33 of Working control device 30 is based on the processing mouth direction vector and the workpiece W normal to a surface vector N of processing head 9, calculating processing corners of the mouth degree θ.Thus, even under the situation of the inclination angle of processing head 9 having been carried out revise in three-dimensional laser processing machine 100 sides, also can in NC data generating unit 34, revise processing head positional information b easily and exactly.
