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 .

Thanks

    It's Easy

    First You Need Row Material Cost; Utility Cost; Manpower Cost; Calculate all as day wise and divided by production meter you got cost of production.

    Sir, seems like u have an amazing knowledge over the subject. Im currently engaged in a a company planning to manufacture geogrids. I have had a detailed study about the various loom machines, their production capacities etc.. What i cant understand still is that how is the RPM of machine fixed at 100 or 200 or 300 watever?? nd why does it vary according to fabric width size, means wider the fabric lower the RPM speed of machine. So is there any formula or logic for this RPM figure calculation. My contact num is 9170536470. I wish u explain nd clear my doubt in detail over the phonecall..

    i didn't get the above formula correctly.
    it is not considering the width at all. there are machines which run at 500 rpm in single width while there are some running at 500 rpm in 136 inches width also.

    Minor Typo error to be corrected, It should be
    Prodn per Shift of 8 Hrs -or-
    Prodn per Day of 24 Hrs

      Dear Its The Conversion of 100 cm to Inches That is 100/2.54 = 39.37 U can Replace the PPi directly with PPcm *100 (ppcm = Pickper cm) for Production Calculation Thanks

    Work with Mr Pedro loans and see the difference in financing because they approved my loan within few days of application after been played several times online then I decided to give a try and work with Mr Pedro on refinancing my business which all went well and smooth than I expected, You can contact him on pedroloanss@gmail.com to obtain your loan at 2% rate.
