4. Background:
Vane blade is a critical functional part of pump and
turbine machinery. Modern CFD design are able to
analyze the flow and optimize the vane blade
geometry. However, this optimized geometry may not
be manufacturable. The current practice is a weeks
long manual trial production that needs a group of
experienced masters.
Objectives:
•Replacing a weeks long manual trial production with
a few minutes of real manufacturing processes
simulation
•Automating the simulation so VaneAdviser is run by
ANSYSY in a batch mode
•Integrating with OptiSlang design optimization
system
•Simulation based path generation
Methodology:
Simulation based Design
Voxel Geometry Model
Design for Manufacturing
Geometry intelligence
Findings & Achievements:
•Schlumberger licensed:
•Singapore Integration Center
•Bartlesville Technology Center.
•ANSYS integration with VaneAdviserB
•A production line was transferred to Singapore.

1. Load STL part file to create raw stock with correct WCS.
2. Instantly load NC tool path and cutters information.
3. Quick simulate machining and automatic verify 5 axis NC program:

7. Computer display of virtual CNC simulation training software package
VIRTUAL CNC Training
Background:
Presently, trainees acquire their machine operating skills by
observing, referring to operating manual and then operating under
the guidance of an experienced operator. The training of skilled
machinists is still a slow and manual process that takes up a lot of
resources in machine tools and fixtures. The machining job has a
traditional image problem of a black smith. This has been identified
by EDB as the No. 1 problem in the Singapore PE industry. CNC
Virtual Lab is the first LEAD (Local Enterprise and Association
Development) project funded by SPRING and WDA to overcome
this problem.
Objectives:
The Next Generation Virtual CNC Training package is through
pervasive physics-geometrical modeling and simulation of multiple
processes, particularly in high speed and ultra precision machining,
to provide knowledge intensive CNC training for the future skilled
machinists of the local PE industry in:
• Virtual advanced manufacturing training and education in
academia and industry
• Visualization of next generation machining operations
• Virtual product and factory
Methodology:
Unified geometrical modeling of multi-axis and multi-processes in
machining.
Project Partner:
Singapore Precision Engineering and Tooling Association (SPETA)
Findings & Achievements:
1.This is the first training system with a 3D solid geometry engine
that could be used for multi-axis machining simulation.
2.The geometry engine could simulate the tolerance of workpiece
machined on six sides with multiple setups. The setup errors could
be reflected in the simulated result. (conventional NC simulation
could not take care of tolerance.)
3.The 3D machine frame, jigs, fixtures, vise, in-process stock,
machining sound and chips flying effects are generated with cutting
force simulation so the trainee will have a feeling of realistic
machining.
4.The 3D jigs and fixtures could be manually operated just like in
the workshop. The workpiece could be moved and rotated with a
simulated hammer and the alignment could be checked with a dial
indicator or CMM probe.
5.The customizable GUI always reflects the latest CNC control
panel that could be updated easily.
Potential Impacts and Industry Applications:
The developed software has been implemented in Singapore and
will be marketed worldwide.

8. At the end there will be only ONE
Unified Deformable Geometrical Model
for pervasive modelling and simulation!
•SIMTech patented a model for representation of geometry, attributes, physical
states and other characteristics of novel processes.
•One model, multiple materials and processes, many industry applications
•The method could be extended to integrate these discrete processes into a
unified geometrical model for pervasive design and verification.
