PROJECT - FAMILY OF PARTS MACHINING
CORE
PRODUCT FAMILY-OF-PARTS PROCESS STANDARDIZATION
ISSUE:
A CNC
machine
tool builder had a prospective customer in the motion controls industry
who
wanted to improve productivity by
implementing
horizontal machining center technology for producing a core product
family-of-parts.
The justification was quantified by MAA comparing present and proposed
methods of the following: lot size, number of machining operations,
setup
time, run time, queue time and lead time. The budget was $500,000
and the timetable 6 months. MAA proposed the process, including
budgetary
numbers for justification, purchase, installation, methodology,
programming,
and debugging. Precision machining was performed within one
operation
on a pallet shuttle system with work piece probing and limited attended
machining. The number of inventory turns were increased
approximately
from 40 to 200. To verify the results, an accounting analysis
captured
all the work-in-progress of the family-of-parts queued to the existing
work centers. The raw material and labor charges were calculated
for all the work orders in queue. The return-on-investment was
realized
in months.
APPROACH:
- horizontal
machining
center with pallet shuttle
- workholding
and
tool holders and cutting tools
- custom
macro B and parametric programming
- automated
workpiece
and tool probing
- broken
tool detection
RESULT: $20 main component to a
$156
assembly cycle
tested and shipped for $800 to $3,200.

ISSUE:
improve
response time to market demand for screw machine cams machined in-house
on conventional machine tools.
METHOD:
purchase
a new CNC vertical machining center, integrate custom hydraulic
fixtures,
and develop and debug a family-of-parts program to generate the CNC
programs
transparently to the cell machinists with zero setup time and with lots
sizes of 1 to many.
RESULT:
standard
cams shipped in 24 hours and custom cams shipped in 4 working days.

G-CODE
REVERSE POST PROCESSING
A common
approach
to programming is off-line, using computer aided manufacturing (CAM)
software
to generate a cutter location (CL) file and then post process the file
into a G-code program for any unique CNC machine. If you have a
post
processor for each respective machine control unit, the CL file can be
re-post processed and the part can be transferred to any suitable CNC
machine. When CNC
machines
are manually programmed, the g-code files can be read into some CAM
systems
like a CL file and then re-processed (reverse post processed).
.
ISSUE:
A
manufacturer
of motion controls systems has a facility in the Philippines
for machining
sophisticated
hydraulic motion control component parts on numerous four axis CNC
vertical
machining centers (VMC) knee mill style. Over a period of greater
than ten years, had created over 4,000 g-code programs. The
programs
contained tool probing, work piece probing, multiple work piece fixture
offsets, tool length and cutter diameter compensation, and man readable
instructions. The existing VMC needed to be replaced, and
management
decided to purchase all VMCs with a bed style. The existing
programs
would have to be converted over to the new machines with pallet systems
and different control units. The company estimated an average of 4.5
hours
to convert and debug each program, implying 3 persons for 3
years.
The timetable and the debugging were expensive. The MAA
alternative
was to directly read in the existing g-code programs individually,
interactively
answer the questions presented immediately after compiling the data,
and
reverse post process the g-code and graphically verify the
output.
The average MAA conversion time was 0.50 hours to convert and debug a
program,
implying 1 person for 1 year.
.
ALTERNATIVES:
- manually
convert
g-code files between machines
- reverse
post process
g-code files between the machines
.
SOLUTION: reverse
post process simply by answering questions automatically prompted
.
BENEFIT: accurate
program conversions in minutes, not hours or days.

PROJECT - 4 AXIS HELIX MILLING
ON EXISTING EQUIPMENT
FAMILY-OF-PARTS
G-CODE
PROGRAM
INCIDENT: a
snowmobile racing components manufacturer wanted to improve response
time
to market demand for snowmobile multi-angle helix clutches. The
clutches
were outsourced for lack of in-house capability of 4-axis (X, Y, Z
&
A) CNC vertical machining center contour milling. The
manufacturer
received recommendations to retrofit the existing machine or purchase a
new machine with a capable control unit. The MAA alternative was
to provide a CAM system with an interactive family-of-parts program
which
could output 4-axis g-code and axis motion on the existing machine and
with the existing control unit. The result was an investment for
a fraction of the cost, requiring clerical data entry of clutch
features
to automatically generate accurate, unedited 4-axis g-code.
POINT: either
purchase a new CNC vertical machining center due to the existing
machine
control unit 4th axis programming restrictions or purchase a CAM system
with a custom program which will overcome the restrictions.
BENEFIT: for
less than 5% the cost of a new machine tool requiring only clerical
data
entry of clutch features, automatically generate accurate, unedited
g-code.

PROJECT- DNC NETWORK

BEHIND-THE-TAPE-READERS
& DNC
NETWORK
INCIDENT:
A local job shop has dozens of
machine
tools. Only 8 are CNC. They included lathes and vertical
and
horizontal machining centers. The machines were
stand-alone.
They were not networked to a PC through a DNC system. Some
machine
were still operated by tape readers and punched tape. First
release
program debugging was expensive, and the readers provided low
reliability.
A simple and low cost investment to improve productivity in program
prove-out
was to eliminate punched tape with behind-the-tape-readers and RS232
cables
connected from each CNC machine to a shop floor computer loaded with
DNC
software for file management, editing and communications. The MAA
upgraded approach provided a very generous return-on-investment.
