Document Type and Number:
WIPO Patent Application WO/2007/077892
Kind Code:
A1
Abstract:
A process for manufacturing a shaped item having high-precision unevenness
and having a surface of large dimension. There is provided a process for manufacturing
a metal shaped item involving the operation of cutting a workpiece by means of
a cutting tool with the use of a machine tool, characterized in that the cutting
operation includes the step of carrying out cutting under such conditions that
at a working point, the cutting tool exhibits a rigidity of 0.1 kg/μm or
higher, a vibration displacement of 50 μm or below, a temperature displacement
of ±0.5°C or less and a cutting speed of 100 to 50,000 mm/min, and in
that during the cutting step, a cutting oil of 0.01 to 50 Pa S viscosity is caused
to flow out at a flow rate of 1 L/min or greater at a position apart from the working
point by a given length selected from the range from 1 mm to the diagonal length
of the workpiece.
