Method and apparatus to test an automatic stop safety feature of a rotary saw

摘要

A test apparatus for testing of a stop mechanism on a saw includes a support arm movable relative to a blade of the saw from a first position to a second position. The test apparatus also includes a simulation member coupled to the support arm. In the first position, the first end of the simulation member is offset from a portion of the blade of the saw, and in the second position, the first end of the simulation member is adapted to be in contact with the portion of the blade of the saw. The test apparatus further includes circuitry operatively connected to the simulation member to replicate an electrical property of a human finger such that contact between the blade and the first end of the simulation member triggers the stop mechanism of the saw.

1. A test apparatus for the testing of a stop mechanism of a saw, the test apparatus comprising:
a support arm movable relative to a blade of the saw from a first position to a second position; a simulation member coupled to the support arm, the simulation member having a first end and a second end, wherein in the first position, the first end of the simulation member is adapted to be offset from a portion of the blade of the saw, and in the second position, the first end of the simulation member is adapted to be in contact with or immediately adjacent to the portion of the blade of the saw, wherein the simulation member includes a first portion comprising a first material and a second portion comprising a second material that is different than the first material, wherein the first portion is disposed at the first end of the simulation member; and circuitry operatively connected to the simulation member, wherein the circuitry and simulation member cooperate to replicate an electrical property of a human finger such that contact between the blade and the first end of the simulation member when the support arm is in the second position triggers the stop mechanism of the saw.
