ABSTRACT:
A method for measuring the machinability of a material which includes piercing a hole through a material to be tested while simultaneously measuring a pierce time duration, T, of the piercing step, and calculating a machinability number from the pierce time duration. Also provided are methods for determining the machining speed of a material and for machining a material which calculate a machining speed for a material based upon the machinability number of the material. The methods used to measure the machinability number and calculate a machining speed for a particular material can include any combination of machining operations, including but not limited to AWJ cutting processes. Also provided is an apparatus which detects the time duration a piercing force takes to create a pierce-through condition through a material. The apparatus includes any of a pressure sensor, an acoustic sensor, an optical sensor, a load cell, a mechanical switch, and combinations thereof to measure the pierce-time duration.
