ELIMIATES IMPROPER UNFOLDING
In VPSS, a programmer verifi es
dimensions and shapes by comparing
the solid model with the orthographic
drawing. As such, improper unfolding is
eliminated without making a test piece.
#3: TEST PIECE VERIFICATION USING
DR. ABE BEND/CAM
AUTOMATIC BENDING DATA CREATION
Dr. Abe Bend/Cam generates bending
operation program for the actual
bending process using AI (Artifi cial
Intelligence). This AI was developed
in collaboration with Dr. Bourne of
Carnegie-Mellon University – the
university with world-wide reputation in
Artifi cial Intelligence for Computer Chess
Tournaments and Mars exploration
robots.
After Flat Layout verifi cation is
completed, an unfold drawing is retrieved
and used by Dr. Abe Bend/Cam for
automatic generation of bending data
in a batch process. The parts to be
fabricated are checked for feasibility
before creating the best bending
programs – bending sequences, tool
selection, L-values, D-values, and tool
placements – automatically without
making any test pieces. If the program
generation results in “Failure” or
“Warning,” reasons shown in Bend/
Cam may be studied to generate
the program manually. This process
greatly increases actual working
because of a reduction in internal
set-up (manual unfold done by an
operator at the job shop) from 80% in
a conventional bending process to 20%
using VPSS.
BEND TOOLING SET UP FOR
MAULTIPLE PARTS
When bending data is generated in
a batch process, common tooling
layout is generated for several parts.
This not only reduces tool set up time as
compared to the conventional way of
arranging tooling layout for each part,
but also realizes higher productivity.
#4: DR.ABE BLANK (LASER/
PUNCHING)
Dr. Abe Blank generates nesting sheet
programs based on the unfolding
drawings created by VPSS. Compared
with creating part data and sheet data
separately and manually, Dr. Abe Blank
reduces the set up for generating
blank processing data and maximizes
material yield.
#5: SDD (SHEET-METAL DIGITAL on
DEMAND)
All data – unfold drawing, solid model
with attributes, set-up information,
processing program information,
etc. – created by VPSS are stored in
SDD as digital information. During
manufacturing, an operator may start
the job immediately and easily by
simply retrieving data from SDD using
a bar-coded “Job Instruction Sheet.”
Stored digital data in SDD results in
common know-how or knowledge,
once reliant on an individual, to
be easily shared within a company.
#6: ASSEMBLING VERIFICATION IN
SHEETWORKS FOR UNFOLD
Sheetworks for Unfold not only enables
verifi cation by assembling solid/sheet
models, but also allows conversion of
solid models into sheet-metal models. All
parts created in Sheetworks for Unfold
may be assembled in a computer and
checked for interference, hole position,
collision, etc. Using this method, solving
errors which conventionally could only be
found only at assembly greatly reduces
wastes in delivery and cost.
#7: vFACTORY
vFactory automatically collects
machines’ information such as machine
history, job history, machine operation,
and machine status by means of
digital data. Therefore, actual working
conditions at a job shop may be
monitored through a remote computer
easily. As such, the capture of present
machine status of machine and results
may be analyzed with the digital data.
It can be seen that VPSS through factory
digitalization will increase cost savings,
productivity, and effi ciency. We trust
that this insight to VPSS will give
you new ideas and technologies that will
not only improve your manufacturing
methods but also increase your
competitive edge and profi tability.
