The 1980's will be the decade of the micro-computer.
According to Lawrence Fiedelman, approximately ei,ghty percent of the computers sold in the next ten years will be
sold to small businesses.
Small business computers are
expected to flood the market similar to the growth of the
electronic calculator. (Infosyctems, Je '79, p. 104+)
BUsinessmen are attracted by the small size, relatively low
cost, small power consumption, speed and reliability of
micro-computers.
One small businessman who was attracted by the features
of wicra-computers, John [.jaryan of fliatt Netal .Froducts
Company Incorporated, recently purchased a Radio Shack
TRS-80 micro-computer.
Hiatt Vetal rroducts is a small tool and die shop
located at 720 ':Jest "!illarci ,c)treet in nuncie, Indiana.
Tho
shop generally employs three office workers and ten to fifteen shop workers.
There are presently five tool makers,
two machinists, three lathe hands, two apprentices and one
general laborer.
The shop occupies approximately
5,000
square feet but will expand to 10000 square feet iL the
near future.
They presently serve ten to fifteen steady
customers, including Broderick, Delco-Fi emy, and V!arner Gear.
Occasional walk-in b:lsin eS[:3 is also handl ed.
Biat t netal
Products manufactures tools, dies, jigs, fixtures and does
precision lathe work as weI] as CliC (Computer Kumerical Control) machining.
The shop consists of three mills, one horizontal
----------_ --_._--_

2
mill, two tracer lathes, five regular lathes, one radial
drill, two internal/external grinders, one external grinder, two surface grinders, and assorted files and sawing
machines.
The shop also has one CNC Bridgeport mill as well
as a recently purchased eNC I'JIAZA:= lathe.
These la[,t two
machines are of particular interest because they are programmable via the TRS-80.
Mr. Maryan originally purchased the Radio Shack
micro-computer specifically to write programs for the eNC
Bridgeport mill.
Mr. Maryan can compose and edit his pro-
grams on the micro-computer and when he is satisfied with
the program he can then produce a paper tape version of the
program which is fed into the CNC mill.
'rhe first three programs in the followinG sections
are designed to prepare paper tapes for the Bridgeport mill.
The tapes are fed into the mill which then drills, bores,
mills or reams according to the given specifications.
The
next two programs (it and 5) are used to calculate certain
points which are needed to program the CNC mill.
The sixth
program is used to create and update programs which will
be used by the CNC mill.
The remaining programs are used for office use.
The
seventh program records the hours spent in each area of the
shop on a particular shop order.
The eighth program figures
the cost of cylindrical or rectangular cold roll steel stock.
The ninth program adds up hours for each employee under
various categories.
The tenth program computes the profit
or loss for the company each week.
The eleventh program
creates data tapes to record information on the jobs done
for each customer.
Finally the twelfth program is used to
update the data tapes created with the eleventh program.
Once all of the data tapes for each customer are initially
created the eleventh program is no longer needed unless
Hiatt Metal Products begins to do business regularly with
another customer.
There are presently twelve data tapes
which are updated at least once per month.
Sinc e the TRS-BO j.s a ree ent addition to )hat t
Netal Products
t~r.
Itaryan is constantly thinking up new
programs to be written.

E'Verytime the Bridgeport mill i.s used to manufacture

J';any times
these programs may be very similar except for a few
lines, where some specification is different.
This
program would allow someone to edit an existing program without having to retype the entire program.
Since many programs written for the Bridgeport may
be over a hund.red lines this editing prograrn VJould
save much time in reprogramming instructions for the
Bridgeport mill.
This program creates new programs for the CNC mill

Once a program has been
If a program is to be
edited the old program tape is read in.

can then:
(1)
Display the entire fi.le
(2)
Display a sinel e line (referc!nced by IT-number)
(3)
Insert a new line (plac ed in correct sequence)
(4)
Chanee an old line

Delete an old li.ne (lines renumbered)

Create a new file (stored on tape)
