Tools for automatic size control. (1982)

Chronicle of 1930.

A woman works on a grinding machine.

Multi-line production.

The first automatic lines.

Airport landing strip.

The take-off of a space rocket.

A cartoon explaining the operation of a device for measuring the accuracy of product processing, a feedback system.

Two issues are solved: accuracy and minimum processing time.

The active monitoring device requires the device to be configured according to

sample.

The setting is set to 0.

The measuring head is inserted into the grinding zone.

The measuring tips are reinforced with diamonds, which eliminates the error from the wear of the tips.

The first task is to measure the processing allowance.

If the allowance is exceeded, the part is excluded from processing.

Stages of processing.

The stage of roughing the part, the main part of the allowance is removed.

Next comes the process of finishing grinding.

The final treatment process is nursing.

The result has been achieved.

At the command of the device, the grinding wheel is withdrawn.

The processed part leaves the grinding zone.

The design of the measuring heads is determined by the type of part being monitored.

The design of the inductive measuring head.

A cartoon explaining the operation of the command and reporting device.

After processing, the part undergoes postoperative control.

Random errors in processing.

The inconstancy of the allowance.

Instability of the hardness of the workpieces.

Instability and heterogeneity of the grinding wheel.

The operator corrects errors.

Bearing.

Accuracy is not only the size, but also the shape deviation and roughness.

The roughness is fixed by special devices.

Investigation of non-roundness deviation.

On the screen, the real profile of the product is compared with the reference circles.

The amount of deviation.

Using the recorder.

Deviations are analyzed by the computer.

An effective way to reduce non-roundness is to increase the number of revolutions of the part at the nursing stage.

Inspection of control devices in the laboratory of the plant.

The second group of active control tools are sub-adjusters.

Automatic feeding of workpieces into the grinding zone.

A cartoon explaining the work of controlling the size of the grinding ring.

When the size of the parts approaches the upper limit of the allowance, the parts are automatically adjusted.

Continuation of the cartoon.

Checking complex details.

The worm is being ground.

The finished part is removed from the machine, checked.

The machine is being adjusted.

The feed of the machine is controlled by a laser.

The cartoon shows the process of checking the quality of the product.

Measuring laser machine.

Automated quality management system.
