Übersetzung für "Grinding burn" in Deutsch

Grinding burn is reduced and higher removal rates are obtained.

These thermal structural changes are often known as grinding burn.

That form of grinding burn is also referred to as re-hardening.

In this way one-sided grinding can be detected, in which grinding burn occurs only on one tooth flank.

For the recognition of surface damage or grinding burn, from the prior art chemical etching methods are known.

This takes into account that concentricity errors in a predetermined circumferential region result in grinding burn and therefore in elevated Barkhausen noise signals, which are particularly strongly weighted.

In particular, the Barkhausen noise signals detected for a component are evaluated as a function of characteristics which represent causes of grinding burn or process defects.

By way of the corresponding intensities these causes can be recognized during the evaluation and thereafter measures can be introduced in order to prevent grinding burn or process defects in the above-mentioned production steps of the component.

Grinding burn is produced, inter alia, if the component-specific annealing temperature is exceeded and occurs in the form of tempering damage as a result of which the hardness at the points affected in the component decreases.

During so-termed Nital etching the component to be inspected is treated with various acids and electrolytes such that after the treatment, surface damage and particularly grinding burn can be recognized by virtue of color changes on the component.

Furthermore a plurality of characteristics are specified, which in each case represent at least one cause of manufacturing defects of the component, such as causes of grinding burn or other processing defects during production.

In the method according to the invention, in particular Barkhausen noise signals from components are processed, for which it is already known that surface damage or grinding burn is present.

The measuring device is calibrated appropriately so that damaged components with grinding burn are recognized from the measured values.

The measured values determined from damaged components then undergo an evaluation in order to identify the most probable causes for the grinding burn or processing defects during the production of the component.

In a first embodiment of the invention, the matrix M is corrected by means of a correction matrix KM, each correction matrix being specific for one characteristic that represents a cause of grinding burn or some other manufacturing defect of the gearwheel.

The multiplication of the measurement matrix by the correction matrix takes into account that, in the case of concentricity errors, grinding burn and consequently elevated Barkhausen noise signals only occur in a particular circumferential area.

Because of the large contact surface and the poor cooling, so-called grinding burn can occur on the tooth flanks of the work piece.

In the embodiment described here, the Barkhausen noise signals from a component are now evaluated further, in order to correlate the signals with causes of the grinding burn or processing defects during the production of the component.

This applies even in the case that all known influences for the formation of grinding burn, such as hardness of the work piece, advancing of the disk, coolant lubricant, etc., for example, are held constant.

The following shows a way of lowering the production time and thus the machining time and/or reducing the grinding burn risk.

It is also possible to retain the production time corresponding to the state of the art and reduce the risk of grinding burn in this way.

In practice, one would realize a combination of the two measures and thus reduce production time and grinding burn risk to a certain amount.

This heat has to be securely removed since “grinding burn”, which is a change in the metallurgical structure caused by overheating, could, together with thermally applied internal tensile stresses in the workpiece, make it unusable.

Only a few years ago very different grinding fluids have been used to get an optimal grinding result with desired surfaces and as far as possible without any grinding burn.

You can dig it up by hand, grind it, burn it, or use a chemical stump remover.

Unfortunately, there are no current limit values for the technological process parameters which, when exceeded, lead to grinding burns.

If you plan to use the altar for rituals that require table space, for instance grinding herbs or burning incense, make sure it is large and flat enough for that purpose.

There were also morphological changes in the environment valleys and found a rudimentary tool to grind cereal, It burned and crushed with stones on which areas could cook a primal dough, similar to it, the researcher.

In particular, in that regard the advancing movement between grinding tool and workpiece shall be such that on the one hand during grinding neither overloading of the grinding tool nor “burning” or faulty shaping of the workpiece occurs or arises and on the other hand the speed of advance and material machining are nevertheless carried out rapidly and efficiently as possible.
