The DF that Lai of benefit of method of China labour laser manufactures technology of dragon door axis and machine of Laser Cutting of DM series numerical control are dragon door mobile form, and for bilateral drive and drive, namely how does the both sides of dragon door beam all contain symmetrically gear rack and servo electric machinery, realize drive of electric machinery of drive of double gear rack, double servo. Bilateral drive makes sure crossbeam suffers equilibrium, crossbeam runs synchronism. Precision of the rate that the beam of door of dragon of synchronous sex influence of bilateral drive runs, acceleration, fixed position and stability. The servo electric machinery of bilateral drive of machine of fiber-optic Laser Cutting takes numerical control of series of DF of Lai of benefit of method of China labour laser coder implementation speed and positional control. Bilateral servo electric machinery has accurate at 0 o'clock the position, after winding reference point at the same time, with double the start that the position regarded synchronism as at 0 o'clock, precision is taller. Buy of v/arc be on the throne of double servo electric machinery controls the synchro control that speed and position finish inside total cycle time, do not have the cent of principal and subordinate, it is the control of the complete synchronism, dissimilation that do not have difference. When dragon door axis does great distance to move, the mechanical error of bilateral drive avoids very hard. The synchro control technology with particular system of numerical control of series of DF of Lai of benefit of method of China labour laser, can be opposite of synchro control bilateral undertake the position is compensated respectively, eliminate the mechanical error of bilateral drive, ensure dragon door axis is in the fixed position precision inside complete width of cloth. The action of axis of F of F axis technology: The control of focusing lens. According to the focal position of expert database set, electric machinery drives focusing lens shift. F axis makes technology of light path compensatory: Lai of benefit of method of China labour laser is own the head of automatic focus cut of research and development more essence of life is accurate, and can use as light path compensation. Wait for the definition of the light path such as light path technology: Laser is exported from laser, each illuminator reach smooth road outside the course the method length of cut head is called light path. Because stimulate horn of diverge of existence of beam of light, reason is different effect of light path focusing and diameter of beam of light are different; Use control technology to be able to make light path keeps changeless when cut head is mobile. Implement the method that waits for light path: Compensation orgnaization drive and drive of Laser Cutting head are common a drive on crossbeam deputy; The athletic way of the athletic way that amends illuminator orgnaization and Laser Cutting head agrees and begin at the same time and stop, compensation illuminator orgnaization is in crossbeam is linear slideway deputy the athletic speed V1 that go up and Laser Cutting head are in crossbeam is linear slideway deputy the scale between the athletic speed V2 that go up is: 1 ∶ of ＝ of V1 ∶ V2 2. When direction of axis of Y of edge of Laser Cutting head motion is apart from 2Y when, distance of compensation illuminator motion is Y, make sure light path length is constant thereby. Power controls key of slope of technical corner power: The occurrence slowdown with inevitable when corner machine tool, laser power can undertake self-correcting according to the virtual campaign speed of cut head. Ask real time sex is close friends. Solder power is rising arc and the control climbing slope when receiving arc, improvement solders quality and form appearance. Power climbs the time of slope to be able to accuse. The understanding of database of expert database technologist: On control technology, we are alleged expert database is understandable the gather that expresses for a lot of pieces of data, numerical control system is called among them the content that a piece of data expresses, have the set of each parameter. Be like: Time of voltage of output of control of athletic speed, power, stiletto (halt time) etc. System of Lai of benefit of method of China labour laser implements the method of expert database: System of Lai of benefit of method of China labour laser offers the interface of expert database, can makings of set parameter, modification parameter, new building materials waits an user a moment to operate. The numerical value after operating is saved for file of a database, save the position to be on CF card. Part program begins the position to index through key word a piece of watch in database file, call the content that this data expresses next. The surface follows the height of sensor induction armor plate on the fundamental cut head that technical surface follows (capacitance or inductance) , feedback gives control the system, control system dominates Z axis electric machinery with this feedback directly, or dominate Z axis electric machinery through after numerical control system is handled, coming by numerical control system, achieve cut head to be apart from plank to maintain changeless effect basically. System of Lai of benefit of method of China labour laser realizes the method that the surface follows to use capacitance type sensor, the change of armor plate height produces the change that capacitance is worth, turn into through oscillating circuit the change of pulse frequency, repass circuit handles the change that is worth for voltage. This voltage value inputs numerical control system, the corresponding relation list that parameter, voltage and career can dominate related the setting. CNC Milling
