HIGH PRESSURE PULSE COOLING MACHINING

 

BRIEF ABSTRACT

The invention proposes a technique to break a chip easily during machining super alloy, such as, titanium alloy. The technique includes a pulsed water jet hammer using a special nozzle. A high-pressure coolant is made to flow through a self-resonating nozzle channel that generates said water jet hammer.

DETAILED DESCRIPTION

Super alloy like titanium alloy is difficult to cut material as the material has low heat conductivity.  This results in accumulation of machining heat that can wear out a cutter tip.

 

A conventional technique includes a cutting tool with a nozzle coolant toward an insert seat. Another conventional technique includes relative movement between work piece and tool with cutting edge.

The present invention proposes a technique to break a chip easily during machining such super alloys. The technique includes a pulsed water jet hammer to create self-generated pulsed water jet by a nozzle when high-pressure coolant flow through a nozzle channel.

The pulse water jet hammer includes a self-resonate jet nozzle to generate high frequency pulse with higher-pressure coolant flow through the nozzle. The pulse water hammer is effective in machining chip. As a result, the chips are broken into a small segment. FIGURE 1 depicts the technique to break the chip during machining of a workpiece.
