My name is Mehdi and I am from New Zealand. I am a toolmaker by trade since 1988; I also do tool design and CNC programming, using Pro/Engineer for quite a while.
In early 2010 I developed an idea for rough cutting on machining centres, it is not an ordinary cutter with different geometry and it is a whole mechanism that acts as a cutter.
It would be considers as a normal tool in tool changing procedure and I believe cutting parameters for 80mm cutter can be approximately:
spindle 500 RPM, feed 2000 mm/min and depth of cut about 10mm.
The material removal rate is significantly larger than even feed mills and the amount of generated vibration and heat in quite low, as result the smaller machines can handle bigger cutters and can be run with coolant at all the times.
I submitted the design with Lambert&Lambert in US for valuation last year and it considered a significantly valuable concept.
I am looking for a company or person that be interested in developing the idea.
