-- head of new-style Laser Cutting raises cut speed effect to regard a machine tool as manufacturer or spare parts manufactory significantly, must make a choice to producing the intelligence of device to change operation rate. Speak of production, no matter be to want to make industrial cut machine, solder machine or agglutination machine, interactive it is current indispensable technology. Today's original conception and company and user, society, university, skill grooms close cooperation of the center, will create tomorrow " sophisticated technology " . To large-scale material sort, norms and configuration, laser Cutting has made a kind of groovy instrument, its apply limits to increasing in stability, and what all these application needs the interface between laser machine and workpiece and machine to have height is flexible. Graph 1: Appearances of all sorts of head of intelligent Laser Cutting consider the flexibility of laser machine to satisfy the special need of final user, developed the cut head of a lot of design and nozzle system in recent years. Stable and consistent cut quality also can produce when although be in,many sensor can assure to handle appearance of plated film workpiece, and sensor and cut head (see a picture 1) unifinication, increased process security and make handling time keeps the smallest change. Successive circumgyrate formula is used in three-dimensional applying the nozzle system that steep drive axis needs slightness, these utility are more and more accurate and complex, accordingly in case nozzle electrode or other surface produces collision, sensor dominates circuit must the interference that can generate to plasma, speed and fault signal undertakes compensating. The product quality that agrees in order to assure stability to control process parameter, use small controller to undertake the process is monitored nowadays and adjust. A of technology of Laser Cutting sensor new development is speed sensor. Punch in the light of laser and sensor of PS 130 process is developed at first, and plan the Lasermatic with Precitec production or head of Lasermatic Z focusing control CO2 laser perforation and cut process together. This sensor system by calculate device, preamplifier and sensor composition, use the visible spectrum that estimation laser machine gives out in cut process and infrared music. This kind of estimation is processing stainless steel or thick it is particularly accurate below the circumstance of board makings, because once produce a mistake,can get instantly,correct. Use PS 130 to be helpful for reducing unqualified or not complete cut. Last year, w.

Company general PS 130 loads benefit spy Buddhist nun PlateLASER system (see a picture 2) . These systems are producing the processing below the environment completely thin plate and thick board, the independent lens axis that this crucial essential factor that handles a process is every system can adjust focusing position in real time quickly. Intelligent laser controller finishs benefit spy Buddhist nun automatically to afore-mentioned lens position is adjusted and assume office actually why of process parameter adjust. All parameter can use material parameter warehouse (Material Parameter Libraries) undertake installing, make guide automatic perforation, automatically, change direction automatically and speed passes process of feeling type cut to be able to undertake real time is adjusted. Graph 2: W.

The PlateLASER system of the company is in benefit spy Buddhist nun initiative development phase of the system, did not use any penetrable exploration methods, because use data of 1-1/4" of PlateLASER system cut when, penetrable process is mixed so quickly stable, so people thinks this kind is explored was not necessary. In perforative process, the focusing seat that wants lens only follows ignition point moves downward, can form accurate alveolus on material. This makes penetrable time the least change, make all round material holds cooling position, drink for accurate cut leave some leeway. Rate of PlateLASER system perforation is high, beardless and add head of alone nozzle, cut or time-consuming punch beforehand operation (see a picture 3) . Nevertheless, to endeavor to make cut process reachs the limit ply is mixed / or the manufacturing level that feed rate still maintains steady, this system needs to provide supervisory and control arrangement. Benefit spy Buddhist nun developed self-regulated type to cross Cheng control options in real time, punch PS 130 sensor regards feedback as the orgnaization, its feedback signal is based on the parameter setting of material parameter library. In perforative process, once indicate the signal n with piercing material to drop, cause perforative routine to stop. Trigger of many signal n was installed in cut process. Once cut process (because material is out of shape, the feature of programmed control geometry that carries out hard) produce a problem, spark signal n prep above normal n. Right now, cut process is decelerated automatically or pause, return normal n till signal. Drop when signal " restore cut to touch hair n " when, feed rate returns regular rate quickly. Want PS 130 signal to rise again only, this process repeats again. If produce disastrous event (cause not recoverable destruction to cut process) , spark signal is achieved " accident signal n " , cause cut process break down and issue caution signal. Graph 3: The monitor of process of form of cut quality self-regulated of sample has profit greatly to final user: Can process data quickly and need not supervise continuously; Can raise feed rate confidently, made breakthrough keeps a level and make cut process with dovish manufacturing level proceed. And, the fast and perforative time of Whitney system can shorten 0.

1~ 2.

0 S, as punch for many times circularly, this can be accumulated make tremendous manufacturing time benefit. The problem is able to be on guard, make cut process can restore automatically or artificial interpose, lest discard as useless,material and waste produce time, and can avoid pair of nozzle, lens or other system component to cause damage. Place of options of monitor of process of form of self-regulated of no less than comes true, sensor punchs quickly besides generation beyond time, still be thick board offer additional function and dependability to assure a method with laminose cut process. The system of blame contact sensor with accurate height is the crucial essential factor of current technology, report of these sensor benefit consumed measure a technology, make a few modernization machine a method to be able to receive reliable application. The innovation that the company will carry optical, electron and mechanical part clutchs development agrees with crackajackly laser material treatment and the photoelectron that process monitoring needs learn and image handles a solution, can create the manufacturing environment of value in order to offer more.
