TOKYO -- February 12, 2013

Mitsubishi Electric Corporation (TOKYO:6503) announced today it has developed
ultra-high resolution 3D shape representation technology for numerically
controlled (NC) machine tools. The technology displays detailed shapes of
machined surfaces down to a resolution of 1 micrometer (um) in a 3D machining
simulation, which machine operators can use to evaluate surface textures
without trial cutting through a high quality machining process.

Key Features

1. Ultra-high-resolution reproduction of processing

  *Displays changes in shape by cutting to a resolution of 1 um
  *Possible to check for over- or under-processing marks, scratches, etc.

2. Highly manageable ultra-high-resolution 3D simulation data

  *Complex shapes are displayed with limited data using Mitsubishi Electric's
    unique Multi-ADF (adaptive distance field) shape-representation technology
  *Runs fast thanks to vastly reduced (less than 1/100) data storage compared
    to conventional high-resolution 3D simulations.

The 3D representation of multi-ADF proprietary technology developed recently
by Mitsubishi Electric uses less than 1% of the storage capacity required by
conventional, high-resolution geometric model resolutions at the 1 micron
level. Multi-ADF represents 3D shapes with a set of tiny cubes each with
refined descriptions of multiple surfaces on them. This technology makes it
possible to display dents and scratches on machined surfaces down to a
resolution of one micrometer using fewer cubes, allowing high-speed
simulations that require little memory.

Development Background

In recent years, the mold processing sector has pursued ways to reduce time by
using high-precision, high-quality machining methods that do not require
polishing. Further, direct processing is being used increasingly instead of
die-mold production, which has raised the demand for high-quality finishing by
Cutting devices are controlled by machining programs generated by
computer-aided design (CAD) and computer-aided manufacturing (CAM) programs.
Actual machining tests are normally done to verify the integrity of machining
programs. This requires a lengthy process of repeated trial cutting to confirm
that high-precision and high-quality machining results are achieved.
Mitsubishi Electric's new technology enables high-precision, high-definition
finishing by simulating 3D machining, which leads to more efficient production
by permitting operators to evaluate surface texture outcomes, as well as by
eliminating the need for tests of actual high-grade machining.
