LINK Systems LinkNet II - Manual (Page 21)

• Run - A run is the production of a certain number of parts from a job. While LinkNet
collects data by date, shift, etc., it also collects statistics by run. For example,
assume 20000 of part number PN-XYZ are made using job number 123 on press
number 456. The job starts on a Tuesday, runs for 36 hours, and ends on a
Thursday. The 20000 parts made would be one “run” of job 123 even though it
crossed multiple days and multiple shifts.
• Down Time Code
- A code used to assign a “reason” that the machine is down (not
running production). Note that in LinkNet, the person entering the reason does
not actually have to remember a numeric code. LinkNet sends the actual
description of the code to each machine on the network. The operator selects
from a list of down time reasons rather than a numeric code.
• Down Time Category - Each down time code has a category to which it belongs. A
category groups related down time codes so they can be considered as a whole.
For instance, job setup may consist of mounting a coil of material, setting the tool
in the press, threading material through the die, and running the process until the
first good part is produced. Each of the previously mentioned individual actions
can be tracked with a down time code, but the total job setup will tracked by the
“Job Setup” down time category.
• Actual Average SPM - The average SPM the press made over all scheduled time. This
DOES count time when the press is on the schedule but down. This does NOT
count time when the press is off-schedule.
• Production Average SPM - May also be called “Average Production SPM”. The average
SPM the press made over all scheduled time when in production (NOT down).
This does NOT count time when the press was idle or down, and does NOT count
time when the press is off-schedule. The intention of this measurement is to show
the speed the press was running when it was running. In some dies, process
limitation (drawing, etc.) can limit the speed at which the process should be run
even if the machine can go faster. On the other hand, we generally want to run
the job as fast as we safely can in order to make money. This measurement
should closely track the stroking speed of the press.
• Job Standard Average SPM - Each Machine/Job combination can have a standard
average SPM. On many reports, the average actual SPM will be compared to this
value in order to generate a machine efficiency percentage.
• Job Standard Production SPM - Each Machine/Job combination can have a standard
production SPM. This is intended to be set to the stroking rate of the press when
running the job. On some reports, a production efficiency percentage will be
generated. This percentage is intended to show when the press is being run too
slow or too fast.
• Scheduled Time - The portion of time that is scheduled as part of a shift. In other words, this
is the time when the machine can be operating. See section 4.7 for details on
schedule configuration.
