Technology of laser of the last few years got rapid development, had turned the cut of a mainstream into the technology. Because have better cut quality and precision, and unapproachable treatment speed, board industry thinks Laser Cutting replaces the technique of Sheet Metal Fabrication of punch predominate extremely likely in the future generally. Besides 2 dimension cut, the sale of machine tool of 3-5 axis Laser Cutting is very hot also in recent years, this basically is much axis treatment has distinct advantage in performance side, to car, aerospace and oil industry, the application of machine tool of much axis Laser Cutting is already special and general. What differ with 2 axes Laser Cutting is, the software demand of much axis treatment to machining process designing is a few higher. Laser Cutting of system of plank Laser Cutting is a kind of costly treatment method, in current and foregone cut treatment, of laser spending cost is highest, and what the advantage of laser beam machining reflects is efficient with quality, improving cut efficiency and product quality so is to reduce the tool with the most effective cost of laser beam machining. In producing a course actually, the engineer must control the treatment craft of cut machine tool strictly, drag in arrives the contrail that the key of craft is material and treatment, in material fixed circumstance falls, machining orbit is the spare time, optimal method that improves efficiency, because first-rate program can save handling time and the utilization rate that raise material, reduce cost quickly thereby. Want to get first-rate program is the most important is the following problems: The first, how use least data as far as possible and do not increase handling time. First-rate method is to use automatic aleatoric appearance to discharge appearance function to identify specific spare parts after actual figure, go up in the material of fixed already size as far as possible had arranged these parts, such word, high material cost is OK instantly a lot of more managing. Use the method that identifies brim of part drawing form to define a spare parts namely like the system of JETCAM Expert CAD/CAM that uses generally in plank cut industry, use automatic random to discharge appearance function next, the spare parts with a few small irregular perhaps parts automatic fill is in a few area, with managing material. The 2nd, how does processing client offer not quite ideal CAD file DWG, DXF or IGES file turn from system of a CAD after coming out, in handing in line and garden arc via often can discovering tiny aperture consist in, very small down to cannot observe with naked eye, much perhaps heavy line, more allow person disclosure hard. And these to discharging appearance it is a very troublesome issue, so that identify its automatically,discharging what appearance needs is the successive geometry graph that close immanent with explicit outline. On this, encounter this kind of problem, JETCAM software will automatically " clear " these files, move what to go to the line of other person unpleasantness, not only won't appear any wrong aperture, and still can call " curve - pour wine cup " function, reduce the amount of short line in great quantities, in order to produce shorter program, reduce the cut workload of the machine, can get good treatment result. The 3rd, the problem JETCAM with the engineer uneven experience that in how reducing process designing process, appears put forward " goofy " the concept of software, the system stores all project data at SEKT system in (abbreviate of Stored Engineering Knowledge Technology of project knowledge base) , although the factory is lacked,machine seasoned engineer so, the engineer of not familiar craft can transfer these technology directly, the program that assures output thereby is first-rate. The principle of cut of much axis of system of much axis Laser Cutting and plank cut differs completely, the spare parts that machines above all was not put on machine tool workbench directly, this locates to a workpiece with respect to drag in the problem of clamping apparatus. On this, the method that comes from the PEPS software of British Camtek company to solve this one problem is very simple and practical. PEPS used a clamping apparatus automatic forms for reporting statistics, install referenced position to undertake fixed to want to process work above all, need the limits of treatment and height certainly, the system can produce proper dimensional reseau by these parameter, generate hypostatic outline graph to support work, after the pitch with affirmatory good corresponding clamping apparatus, these hypostatic clamping apparatus can make 2 dimension plan automatically form, press the size of clamping apparatus board that offers beforehand, make the graphical file with automatic group good appearance and NC cut file. The 2nd common problem is the industry that much axis cut faces three-dimensional hardware design replaced 2 dimension blueprint already completely, what the client offers is a few three-dimensional spare partses, and the problem that the engineer often encounters passes data changeover to come in namely the broken face that the graph exists generally to twist is out of shape or have a lot of, and current situation of current standard of data changeover technology decides this kind of situation is changed very hard. And the administrative issue that the modification of these three-dimensional graphs still involves blame technology level, normally the client is the demand that accepts need very hard to revise them to provide a model, because they fear these modification meetings do not accord with their need PEPS to solve the method of this one problem,be to offer a large number of CAD to change interface above all, what want a client to use only is mainstream CAD three-dimensional design software, PEPS can be changed directly and do not need changeover to be tripartite format. These mainstream CAD software include Pro-E, catia, unigraphics, solidWorks, solidEdge, cimatron, delcam is waited a moment. Current of course and general accepted is ParaSolid format in three-dimensional changeover the respect has the advantage with stable, broken face and broken little face, PEPS also offerred technology of this one kernel to the user. Next PEPS offerred quite strong adjustment function, be opposite especially hypostatic spare parts. These functions include complete repair a function in the round, the curved surface when treatment plans to combine a function, the faintness of section curve is chosen etc, the intensity of reduced an engineer process designing job with these likewise valid functions. In burgeoning industry country of the Asia, although the application of Laser Cutting still is done not have Euramerican gain ground in that way, but of the move as global manufacturing industry and Laser Cutting cost reduce, laser Cutting can receive more application very quickly in these countries. The client of Dan Yazhou country puts generally in an error: Take hardware seriously to despise software. Bought come from European high-grade machine tool costlily, and the Euramerican software that do not use any software or buys a few low end, the result is these machine tools did not get be usinged very well, cause efficiency low, the loss outweights the gain, especially the Laser Cutting machine tool to be in high end, if do not undertake rising in efficiency respect, cost can be very costly.
