Then, movement of the tool in an X-axis direction is started first, and a rotation position of a spindle is monitored. When a thread-cutting start angle of the spindle is detected, cutting feed in a Z-axis direction of the tool is started if the tool travels in the thread-cutting startable area. |

Measuring deflection to determine a characteristic of a cantilever
Disclosed are methods that, by not physically touching a material being measured, can measure the material's differential response quite accurately. A collimated light shines on the material under test, is reflected off it, and is then captured by a device that records the position where the reflected light is captured. This process is done both before and after the material is processed in some way (e.g., by applying a coat of paint). The change in position where the reflected light is captured is used in calculating the deflection of the material as induced by the process. This measured induced deflection is then used to accurately determinate the stress introduced into the material by the process. Other characteristics of the material under test, such as aspects of the material composition of a bi-metallic strip, for example, may also be determined from a deflection measurement. |
