ACM run mode, 3 kinds of means are chosen among them one of. Condition is surveillant, overload, move, main shaft, online / wait for condition from the line. Main shaft power and feed rate are curve of real time change and numerical value. Run a cost currently, referenced number, spare parts number, begin handling time, run workpiece of time-consuming, cutting time-consuming, managing when using (% ) , the smallest feed is led (% ) , the biggest feed is led (% ) , repair tone pitch currently (% ) . ACM job mode: ACM starts / suspend way: Through function of NC program H automatic or the hand is moved start / stop to move. Cutting parameter inputs means: Cutting parameter if, material of number of cutting tool type, tine, workpiece, cutting is measured (deepness) with speed can the hand is moved (Preset) perhaps learning (Learn) means is self-recording cutting parameter, after learning next (By Learn) means according to record parameter, monitoring machine tool moves. ACM run mode: Feed controls fashion: ACM measures main shaft load continuously and self-adjusting feed leads real time, occurrence overload is given out call the police stop a machine tool. Monitoring means: ACM measures main shaft load continuously but do not adjust feed rate, mode of two kinds of monitoring offers an alternative, the biggest laden monitoring or laden allow poor monitoring. Incident records pattern: Just store dynamic cutting data in this means ACM in systematic memory, do not do output to handle. The characteristic of OMAT ACM and cutting tool of treatment of effect tradition metal rupture cannot detect and control, cutting tool wears away armrest moves surveillant, efficiency low, and of OMAT ACM system posed a challenge to traditional processing technique from adaptive control technology, optimized metallic cutting CNC to machine a process, rose to machine efficiency. Representative application statistic: When outline milling is saved, make an appointment with 38% ; When mill chamfer is saved, make an appointment with 34% ; When 3D mill face is saved, make an appointment with 37% ; When bore is saved, make an appointment with 28% . And have following protection function: Milling cutter ruptures protection (call the police and stop machine prevent workpiece and damage of follow-up cutting tool) ; Cutting tool of deep Kong Zuan ruptures protection (call the police and stop machine) ; Cutting tool wears away monitoring (the number shows wear extent) ; Main shaft overload is protected (call the police or stop machine) . Because OMAT ACM is distinctive from adaptive control technology, the effect is distinct practical, a lot of well-known companies are like abroad Siemens AG, Turbinenwerke, Chevron Aerospace, Boeing, General Electric, Mitsubishi Motors, the company such as Toshiba GE and Toyota Motors already was used in great quantities, obtained apparent effect. Hand in Inc. of science and technology of machine of big elder brother and cooperation of Israel OMAT company, system of successfully ACM of Composite of will unit soft hardware is compositive install the 840D system at machining center of horizontal of THM4680 of product machine tool to go up, still did test of contrast of cutting of bedding face workpiece, cutting efficiency rises about 33% . The machine tool load capacity of ACM changes control and the safe protection function to cutting tool, main shaft, make handlers is at ease the full load of utmost uses a machine tool, and unapt cause harm to the machine tool. This applies to the horniness material such as cast steel of face cutting, treatment, mould to machine course of study, deep Kong Zuan to cut especially, the user such as cutting tool of entrance of use high price. The well-known company of the industry such as domestic aerospace, spin, home appliance also takes the lead in using this product in succession. Believe as CNC Machining technology, high speed the advanced metal such as cutting machines what the concept is in domestic company to popularize application, get used to processing technique to be able to get applied extensively certainly oneself.
