Process stability plays a significant role.
In conjunction with shown in Figure of description three, increasing material manufacturing carried out to diagram bend pipe 16, first have to cut the structure
Piece processing, inevitably generates hanging face 19 in the fabrication process if being sliced according to conforming layer 17, and laser is same
Axis powder feeding technique can not manufacture hanging face；If uneven layer 18 can be obtained by carrying out slice according to bend pipe curvature, five are being made full use of
It can only be manufactured when can completely avoid hanging face under conditions of axis linkage, but being processed with fixed laser power and speed
Even layer 18, this just greatly limits five-axle linkage and increases material systematic difference.
It should be noted that laser ranging system 8 is used to measure its own to the distance on molten bath top, the distance is whole
It should be a fixed value in a increasing material module routine, if measurement distance is greater than the fixed value, pass through feedback system
10 reduce laser travel speeds to improve current cladding band height, and on the other hand, one-sided reduction speed will lead to molten bath and become larger,
Cladding band broadens, and then influences Product Precision, and the present invention captures the change in size in molten bath using CCD camera 7, when molten bath increases
When, then laser power is reduced by feedback system 10, and then adjust pool size to zone of reasonableness.This dynamic parameter system was both
It ensure that the stability of whole manufacturing process, and make uneven layered be manufactured as may.
Multidate information feedback system includes travel speed control system and laser power control system.Travel speed control system
System is used to control cladding band height, this control process is realized using PID loop control algolithm in the present invention: first according to reason
By laser ranging system under cladding band height defining ideal state to molten bath top distance Lt；Laser Measuring is utilized in process
Practical laser range unit is obtained to molten bath top distance L away from device measurementm, utilize LtAnd LmDifference e (k) be used as PID loop
Input quantity calculates output quantity U (t) by following formula:
Wherein e (k)=Lt–Lm；The difference that the previous time point of e (k-1) representative obtains；Kp, Ki, KdRespectively ratio system
Number, integral coefficient and differential coefficient.Gained output quantity U (t) is used directly to define a 0-10V analog electrical signal, the signal quilt
Machine tool control system, which reads and passes through user's custom variable system, gives system travel speed assignment, and then utilizes dynamic speed machine
System cladding is compensated with excessive height/too low situation so that processing in laser ranging system to molten bath top distance into
One step levels off to Lt。
Laser power control system is then used to control pool width, patent (CN 201510270345.3) and
(CN201610253396.X) pool width is adjusted by adjusting laser defocusing amount；Patent (CN 201710349069.9) is logical
It crosses preliminary experiment and measures laser power-pool width relationship, then added by adjusting laser output voltage adjusting laser power to change
Pool width during work.But because travel speed also will affect pool width in process, folk prescription can not be passed through
Laser power-pool width relationship is established to adjust pool width in face.The present invention is still incorporated into PID loop control algolithm and carrys out dynamic
Pool width is controlled, defines target pool width D firstt, practical pool width D is measured by CCD cameram, utilize DtAnd Dm's
Difference e (k) is used as PID loop input quantity, calculates output quantity U (t) using aforementioned formula, and directly adjust laser using U (t)
Output voltage, and then laser power is adjusted, so that pool width further levels off to target value L in processingt。
Above-mentioned, although the foregoing specific embodiments of the present invention is described with reference to the accompanying drawings, not protects model to the present invention
The limitation enclosed, based on the technical solutions of the present invention, those skilled in the art are not needed to make the creative labor and can be done
Various modifications or changes out are still within protection scope of the present invention.
