SU1303996A2 - Adaptive control system for metal-cutting machine tool - Google Patents

Abstract

This invention relates to adaptive control systems for a cutting machine. The aim of the invention is to improve processing performance. The adaptive control system contains the cutting power stabilization circuit 1, the control object 2, the first 3 and second 4 vibration damping blocks, whose input through the comparison element 6 and the vibration sensor 5 are connected to the second output of the control object 2, the first output of which is connected to the second input cutting power stabilization circuit 1. The outputs of the first and second vibration damping units are connected respectively to the second input of the control object 2 and to the first input of the cutting power stabilization circuit 1, the output of which is chen to a first input of the control object. The second input of the comparison element 6 is connected to the output of the setpoint adjuster of vibration 7. The series are connected to the system of the tool wear rate 8 and the extreme contour 9 for adjusting the setpoint of the allowable vibration amplitude, the output of which is connected to the third input of the comparison element 6, and the second input to the output of the comparison element. 1 il. with S (L o so with so with Oi

Description

The invention relates to automated radios blocked by negative signic control of machine tools, in particular h - ho (the same alarm signal to adaptive control systems of vibration damping 3 and

laziness and loading level4). main drive. 5 In the event of the occurrence of a vibration-resistant invention, an increase in the penetrating mode of vibration cutting and the processing efficiency due to the elimination of the hardware above the permissible level, h

promptly adjusting the amplitude h of the work, the instrument’s functions as functions of the instrument depend on the specific situation or

wear., 10block 3, or blo1 4. Vibrations at

In the drawing, the device is reduced to an acceptable level in the form of a functional circuit. Sensor 8 measures the speed g

Contour 1. stabilize power tool. At the moment when the output is connected to the first input of the vibration-proof mode of control 2, to the second input of the circuit, circuit 9 is unlocked from which the first block 3 is connected with a h-h signal and the target of vibrations is. The second block 4 modifies the total signal

Claims (1)

No vibrations are connected by the output from per-b + db in such a way that the contour 1.condition of wear and tear is minimal (the sensor of 5 vibrations is connected to the output of this circuit is similar to the operation of the first vibration damping unit). In the further comparison, on the second input of which, despite the difference that the setpoint adjuster 7 of the allowed level h - h ± db is reversed, the sign of the relative vibration can be changed. Speed sensor 8 from tour 9 is unlocked until the next removal of the tool is connected to the inlet 25 of the go to the section without cutting, at the contour 9 of the extreme regulator, the wear rate of the tool of the vibration level, the output of which is 0. is connected to the third input of the comparison element 6 Formula. The system works in the following way. The adaptive control system mePri vibration resistant cutting by this cutting machine according to the author. St. The theme stabilizes cutting power No. 996997, different from N at a given level of N regulation — so that, with a price, I will increase the output of the S..35 deduction, it will be additionally introduced using the setting device 7 for each sequentially connected tool size range to determine the tool wear rate and is the value of h. In the case of an extreme control loop CNC devices of the type H setting the m-setting of the permissible amplitude of the vibrations are performed automatically. So 40, the output of which is connected to when the vibration-resistant cutting of the first input of the first element is comparable. b then circuit 9 is extreme and, and the second input is to the output of this twitching the permissibility of a vibration element.
