When the real-time representation of structure that creates.The noise of record can be associated with the details of structure of storage in the database.Pass through
The circumferential position for being associated with recorded noise and thus obtained structure and being monitored, can observe and monitor created structure
Position.
In one embodiment, the device for controlling actuator includes numerical control device so that machine order
Intervention of the input, compiling and transmission of information without operator.
In one embodiment, the equipment further include for by the structure monitored and given predetermined structure into
Row compares and adjustment is used for the actuator of control process tool and/or for driving the motor of emery wheel extremely based on comparative result
The device of few control pulse.Described device can be integrated in the device for controlling actuator.By will be monitored
Structure be compared with given predetermined structure, control circuit, specifically real-time control circuit can be established.
Method for controlling the equipment having been described further solves this purpose.It the described method comprises the following steps：
The structure of the difference created on grinding wheel surface is monitored, and
The circumferential position and/or rotating speed of emery wheel are monitored,
According to the structure monitored and the circumferential position monitored and/or rotating speed come the actuating of control process tool
Device.
The advantages of being described with reference to the equipment and other embodiments are also applied for claimed method.
The exemplary implementation scheme of invention
The other embodiments of the present invention are disclosed referring next to attached drawing.Attached drawing shows the signal of equipment according to the present invention
Figure.
Equipment 1 include for be pivotably supported will in equipment 1 processed emery wheel 2 emery wheel support element 14.Horse
It is rotated up to 20 driving emery wheels 2.Magnetic circumferential position sensor 8 is provided, to monitor the practical circumferential position 19 of emery wheel 2.If by pair
The circumferential position value of dry monitoring is differentiated, and the rotating speed of emery wheel is obtained.
Handling implement 4 includes diamond tip 5, which connects during processing procedure with the surface of emery wheel 23
It touches.Handling implement 4 is supported by handling implement holder 6.Actuator 7 can manipulate the position of handling implement holder 6 along different directions.
Specifically, by changing the position of handling implement holder 6 in the x-direction, adjustment diamond tip 5 invades in the surface 3 of emery wheel 2
Depth.
Control unit 10 is that handling implement actuator 7 provides control pulse 16.Control unit 10 is provided with about needs
The predetermined surface 3 created on emery wheel 2PData.Several predetermined structures 11 are provided in these data.Pass through emery wheel 2
Circumferential position signal 19 provide it is synchronous with the practical circumferential position of emery wheel 2.
Acoustic sensor 13 is provided, the noise 18 occurred during surface 3 is invaded for being recorded in diamond tip 5.Base
In depth of invasion, the power being applied on tip 5, the duration of intrusion and encroachment area, the noise 18 of different wave spectrums is generated.Cause
This, when creating different structure on the surface, the noise for generating different frequency and volume (then summarizes ground and is known as term noise waves
Compose (noise spectra) 18).The library of different noise wave spectrums 18 and distribute to these noise wave spectrums structure 12 details quilt
It is stored in database 15.Consider emery wheel 2 tach signal 19 in the case of, by comparing record noise wave spectrum 18 with deposit
Store up the noise wave spectrum 18 in database 15, it may be determined that structure 12, the structure 12 are created with when recording corresponding noise 18
Structure it is similar.This determination is executed by analytic unit 9, which can access database 15.As a result, analysis is single
Member 9 establishes the observation surface image (observed surface image) 3 for including monitored structure 12o。
Due to the abrasion of the supporting structure of the abrasion or emery wheel support element 14 of handling implement 4, it may occur however that processing procedure
Accuracy reduces whithin a period of time.As an example, Fig. 1 is on observation surface 3oIn show deviate predetermined structure 11 structure
12'.This indicates the excessive wear of handling implement 4.This abrasion can be compensated by correspondingly changing the control of actuator 7.
For example, the loss of the diamond particles at tip 5 can be compensated by the increased feed rate of actuator 7 in the x direction.Root
The possibility of the feed rate in adjustment control circuit in real time is provided according to the device and method of the present invention.
