The longest time of
Production CT in a
program.
Continuous Production CT
is a cycle time from when a
board arrives at the exit till
when the next one arrives
there.
By counting the CT except
the first board, it indicates
a cycle time with the
boards staying on each
stage of multi stage
machines.

time from when it starts
producing till when it
arrives at the exit of the
last stage.
It indicates at how much
interval to produce boards.
The difference from
Continuous Production CT
is to count the first board,
which enables it to indicate
the average of the
program.

The numerical value shown with the following formula is computed with Working Ratio.
Working Ratio is measured in the lot unit, and Working Ratio adopted here is the time when setup time
was omitted.
＜Working Ratio＞
(Total Mount Time + Total Transfer Time)
Working Ratio (%) = -------------------------------------------------------------------------------------- x 100(%)
(Production Finish Time－Setup Finish Time)－Total Standby Time)
<Working Ratio on each stage>
(Total Mount Time of a stage + Mark Rec Time of a stage + Total Transfer Time of a stage)
Working Ratio on each stage (%) = ---------------------------------------------------- x 100(%)
{(Production Finish Time – Setup Finish Time) – Total Standby Time}
(Total Mount Time of all stages+ Mark Rec Time of a stage + Total Transfer Time of all stages)
Working Ratio of WCH (%) = ---------------------------------------------------- x 100(%)
{4(Production Finish Time – Setup Finish Time) – Total Standby Time of all stages}
<The explanation of each item>
Total Mount Time :The total mounting time. Mounting time means the time head unit moving
(include mark recognition, error retry).
Total Transfer Time :The total transfer time by conveyor transferring board.
The time when Machine is working when these two are added comes.
Setup Finish Time : The time to start running after board switching is done. (Time to stop by the
setup work isn't contained after board switching is done.)
Production Finish Time :The time when switching next board data.
Total Standby Time : The time when the head isn't moving by Upstream standby or downstream
standby.
The result that it can get from the above formula is the time when the machine can move. When it
wrights simply,
The Time the machine worked actually
Working Ratio (%) = ------------------------------------------------------------- x 100(%)
The time the machine can move
