    when a control plan is developed and prepared subsequently for each phase of the product to be produced, controls are drawn up to be put into production on the machine for each sentence. What is the difference in fact yes the contents are always the same they are just divided by production phase?
    Who knows how the plan and then the control cycle should be carried out? Is it just an extract from the control plan for the production phase?

    Do you have an example you can share to explain your question?

    Jonathan85 - I’m sorry but I don’t understand your question either…

    Let me explain better, I hope I can,
    I draw up a control plan for the processing of a particular oat with 3 work phases.
    op.10 blanking
    op.20 folded
    op.30. nut welding.
    then in my work experience the contents present in the control plan for each phase are taken and inserted as is into a control cycle for each work phase
    cycle op.10 blanking
    cycle op.20 folding
    cycle op.30 nut welding.
    my question and doubt is
    Is there a different method than this?
    Is it right to proceed like this?
    Are the machine control files for the production worker and for any recordings with stable frequencies simply extracted from the control plan?

    Did you create a process flow and PFMEA before the CP?

    The PFMEA tells you what should be in the CP?

    the contents of the control plan are present and details
    my question is
    if I have the complete CP with all the process and product characteristics to check,
    the document that is made available in production for operators "called the control cycle". is it simply an excerpt from the control plan?

    "control cycle" - I have never heard of such a document. Typically, instructions are developed from the CP (because the CP can be too complex for operators) and posted for the operators to reference. I'm not sure what is excerpted, the instructions should reflect the requirements for process control.

    non ho un inglese buono purtroppo
    Istruzioni di lavoro che tu intendi vengono sicuramente prese dal piano di controllo,
    Ho sempre visto preparare il CP e scrivere in un altro documento fase per fase le stesse identiche cose,
    , allego un esempio forse riesco a spiegare meglio, ho evidenziato in giallo la fase .

    Interesting. I have never seen a document such as your ciclo di controllo. Who creates it? Who uses it?

    Vieni usato dagli operatori in linea di produzione per i controlli da effettuare,viene creato dall'ente qualità.

    In which case, the answer is, yes, this seems fine, using your ciclo di controllo. Others use work instructions, but this is your choice. As long as the ciclo di controllo is accurate to the CP that should be OK
