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.
