Device for measuring the machining forces of tools

The invention relates to a device for measuring the machining forces of tools, the elastic bending of a machine element which is involved in the tool drive or workpiece drive being measured. For this, the bending-proportional or force-proportional distance between the machine element and a pick-up mounted on this machine element is registered. The advantage of this invention lies in the particular simplicity of the assembly, the low space requirement and the high measuring sensitivity of the bending measurement, which is as a rule superior to a measurement of the longitudinal expansion. As a result of the integration of the measuring electronics in the pick-up, the output signal has a very low resistance, that is to say the measured value transmission cannot be disturbed as a result of relatively small cable or plug and socket leaks in contact with moisture, completely in contrast to piezoelectric expansion pick-ups. In contrast to expansion strain gauges, separation of the pick-up, which is fastened with a screw, is not possible.

Apparatus, methods, and systems for high throughput, useful sampling of seed, wherein viability is optionally maintained, are disclosed. Seed from one generation in a plant advancement experiment is individually sampled by removal and collection of tissue from the seed. The tissue is then processed to derive one or more biochemical, genetic, or phenotypic characteristic of the seed before a decision is made whether to utilize that seed further in a plant advancement experiment or other plant research and development. In some embodiments of the method, the sampling is controlled to remove a useful amount of tissue for analytical purposes without significant effect on viability potential of the sampled seed. In some embodiments, the sampling is controlled to deter contamination of the sample. In some embodiments, the seed is automatically positioned and oriented to facilitate efficient and accurate sampling.
