Project theme:
SIP (Cross-Ministerial Strategic Innovation Promotion Program)
/ Innovative Design and Manufacturing Technologies,
“Development of Innovative Intelligent Machine Tool by CAM-CNC integration"

  An intelligent machine tool is not realized under the existing method in
which machining operation is instructed by a part program or an NC program.
Therefore, a new methodology to generate instruction commands for prompt
machine control instead of preparing NC programs is developed to realize an
innovative intelligent machine tool. This machine tool can contribute to
achieve needless of NC program preparation, control of cutting process,
shortening of production lead time, and realization of autonomous
distributed factory. Shortening of production lead time is effective to
realize tailor-made production of dies, molds and artificial bones.
  Contents and achievements in our research and development are summarized
as follows.

(1) Development of key technologies I: Cutting force simulation (Kobe
University)
 A new cutting force simulator which calculates discretely uncut chip
thickness by referring workpiece voxel model has been developed to predict
cutting force in end-milling operation. This year, cutting force prediction
in ball end-milling operation can be achieved.

(2) Development of key technologies II: Adaptive control system (Kobe
University)
 A new methodology to realize adaptive control or tool feed speed control
based on the predicted cutting force is developed by integrating with the
digital copy milling system which can generate tool paths in real-time
during machining operation.

(3) Development of demonstration software I: GUI of Digital copy milling
system (SoftCube Co. Ltd.)
 In order to install the developed demonstration software into CNC, a new
GUI is designed. Only 4 steps, (1) Product model selection, (2) Work model
selection, (3) Process planning and (4) Starting machining operation, are
needed to start machining operations.

(4) Development of demonstration software II: Bug fix in tool path
generation algorithm (SoftCube Co. Ltd.)
 The problems found in cutting test are solved by fixing the bugs in tool
path generation algorithm.

(5) Development of demonstration software III: GUI of Digital Copy Milling
system (SoftCube Co. Ltd.)
 A new demonstration software is developed based on a new algorithm of tool
motion control (tool feed speed control) developed by Kobe University in
fiscal 2014. This software sets the tool feed speed automatically in voxel
properties of removal volume voxel model corresponding to a workpiece.

(6) Development of the 1st prototype machine (Kitamura Machinery Co. Ltd.)
 The demonstration software of digital copy milling system is installed in
CNC. The 1st prototype machine to achieve 3D printer-like machining
operations is developed to display at the EMO MILANO 2015.
