Abstract
An alarm system including a battery powered transmitter received in a watertight housing. The housing includes an outwardly extending shank. The shank is adapted for receipt in a tool holder stored in tool change magazine. The magazine is mounted inside a high speed CNC milling machine. When the milling machine completes a work cycle on a work piece, it is programmed to activate an automatic tool changer that retrieves the tool holder with transmitter from the magazine and attaches them to a tool spindle. The movement of the machine is then used to activate a radio signal button on the transmitter and send a radio frequency signal to a battery powered receiver disposed outside the milling machine. The receiver than activates an alarm. The operator is then alerted that the milling machine has stopped operating and needs to be attended.
