Abstract: Proposed is a method of determining optimal operation conditions for treating holes with a rotary tool by performing a hole treatment operation on a tester under various treatment conditions which are similar to the use of the tool in the industrial production on a real manufacturing equipment.

Abstract: The disclosed embodiment is an extensometer to measure transverse strain with a passive vertical system making use of a linear optical encoder. The sensor arms are mounted on respective carriages which traverse on respective linear tracks. The carriages are spring-loaded so as to bias the sensor arms toward a closing direction. In order to separate the sensor arms and act against the force of the springs, the carriages are responsive to or pushed by upper and lower drive brackets which are affixed to respective upper and lower portions of a looped timing belt. The extensometer makes use of a low-friction design to minimize rolling friction in the movement of the two sensor arms. One carriage includes an encoder read-head which directly faces an encoder scale on the other carriage. In this configuration, the exact relative position of the two carriages, and hence the two sensor arms, can be read.
