PRODUCTION CALCULATION FOR WEAVING LOOMS.


PRODUCTION CALCULATION FOR WEAVING LOOMS




Weaving Calculation for weaving looms differ from different types of machines .But the Basic calculation remains the same .

Factors which effect the production are only two main things .

1) RPM (Revolution per minute )  of Machine .

2) Weaving Efficiency .



What is 100% production  of any given machine in terms of picks .

= RPM    X    WORKING HOURS   X   60

RPM  means that for every revolution of the motor one pick inserted .
60 signifies the conversion factor  of hrs to minutes .

For example :- My machine runs at 600 RPM  for a shift of 24 hrs .

Then the Total Picks inserted for the day

= 600 x 24 x 60

= 864000 picks

Therefore at a given day at 100% efficiency  864000 picks are inserted .


Calculating Production 

Nowadays on modern machines calculating the production on the machine is not tedious .

We get all the information on the machine panel .

Thanks for the Technology .

Today there are counters on the machine to calculate the number of picks inserted .

This information can be taken manually  from the machine , or installing cad /cam system provided by the machine manufacturer or by different interfacing  hardware /software available  in the market .

Factors affecting the productivity of a machine .

1) Efficiency .
2) Picks Per Inch / Cms.


Efficiency  of the machine  = (Final Reading of the machine  - Intial Reading of machine ) x 100
                                                            Total no of picks @ 100% inserted ( 864000)

Production per shift of 24 hrs in mtrs 

                        =  Total no of picks inserted per shift / (picks per cm   x 100 )

or

                     = Total no of Picks Inserted per shift  /  ( picks per inch x 39.37 )



Total  no. of Picks    = (Final Reading of the machine  - Intial Reading of machine ).




Conclusion :-

Production of Loom  =  (RPM  X  WORKING HRS  X 60  X EFFICIENCY %)  /  ( PICKS PER INCH X 39.37)


Hope This Information to all my friends .
