1- is it possible that the customer give me a sample and told me to make this ?
but the factory will responsible about the design not the customer ?
and responsibilty to review and verification of design process ?
This depends upon what you and the customer have agreed to. At the very least this should be part of your contract review where terms, conditions and responsibilities (in cases like this) should be agreed upon and stated. It is possible either way.
I would be somewhat suspicious of a company which brought me a part and asked me to make prints for it and to produce it unless they could explain how they got the part to begin with. Again, where did the part they give you come from? Is it an old part that the original prints were lost? How will you know exactly what the material specifications are, and again, as I have said, how do you know what tolerances to use on the print?
2- in the above case where i am responsible for the design i will make the validation ? and how to make this validation ? can validation and verification consuct as one step ( analsis and measuring of specification ?
First off, verification and validation are completely different things.
Definition of Verification and Validation
Again, you will have to ask your customer their expectations. You may not be able to validate the design. Do you know it's function? I this a single piece part, or is it an assembly?
If YOU are design responsible, it is up to you to have a procedure to follow and part of the design process is to determine if, and if so how, validation will be performed.
In my past life, many years ago, I wrote Environmental Design Criteria Test Plans. They are essentially design validation plans. My company was design responsible. For each different product I had to determine what the assembly would be exposed to and from that and other information I would write up a validation plan. But - There are things you have to know, such as where and how it will be used. For example, I was involved in aerospace electronics, so to validate the product I had to write in the test plan many things such as altitude tests, vibration and shock tests (with justifications for the profiles used {e.g.: broadband on sine vibration}), explosive atmosphere, temperature and humidity, MIL-S-901 torpedo shock, etc. I did this by profiling the life cycle of the assembly, mixing in reliability information/data, etc.
So - In short you and the customer have to decide what validation is appropriate for the part but you need information about its use and such. And as I pointed out earlier, there are things which can only be validated 'in use'. The example I gave was an elevator cab. You can give a supplier the design (prints, etc.) and all that, but until it is actually installed in the elevator shaft with all the components working the cab cannot be fully validated. In a case like this a company like Otis sends out prints to several suppliers. Otis is responsible for design (and therefore validation requirements) but the companies which make the cabs just make and ship them.
3- if we consider the customer is responsible for design and we exclude the clause 7.3 how we treat the matter of getting the sample and make drawings and sketches ?
can we consuct at as product realization as planning and provision of product
The customer should have a design procedure. They should be telling you what they want and how they want it. If the customer is design responsible it is their responsibility to tell you what is expected from you in the way of design inputs and outputs, including time line, prints and things like that.
As to how to 'getting the sample', are you referring to getting a part, doing the prints, etc., and then making a sample part to give (or sell) to the customer?
