content: Hello everyone.My name is Sami. I graduated from mechanical engineering department two months ago and started to work last month in a company that manufactures composite wind turbine blades . They want me to make measurement on blades, moulds and machines that used in production. i will use CMM devices such as Foro Laser Tracker and Faro Arm. But i don't know anything about metrology. So i would like you to help me. Can you answer my questions ?1. How to become a good metrology engineer?2. What to know ?3. Which training (like GD/T, Calibration) should i take to become a competent engineer?4. what are these that has to be considered when CMM devices are being used?If answering by writing will be inconvenient for you , we can organise a Skype conversation. My mail adress is sami.dmr35@gmail.com(I am really in a bad situation and I have to start benefit my company as soon as possible.)Thank you in advance.your sincerely;

content: Your manager at the company you work with should provide you with the guidance. He must clearly state what he wants (KPIs), and he has to understand well what trainings you would require to perform well..

content: As important as metrology is, it's surprising how few courses and programs there are covering the details of it. In many companies it's corporate knowledge that's internally maintained and taught. You may have to work with the vendors that supply the equipment, plus take some statistics courses (maybe you already have those?), then study every possible commercial standard for the products you make. It may help to search for "quality" topics, rather than "metrology" topics, as there are way more conferences and study materials on that. IMO, the big problem for the type of things you make is liability. If something fails, every part of the production and quality process will be put under a microscope and you better be able to justify the decisions that led to the processes used.

content: I would like to expand a little bit on the last two posts, which are both correct, but probably don't go far enough.First, you, yourself, ought to be a just a small part of the overall quality control process. Since there is actual legal liability involved (e.g you could go to jail if you screw up badly enough) you want to understand your part in that whole process. As imo says your manager should be able to answer those questions completely and transparently. (If not, red flag).At the end of that conversation with your manager you ought to be able to come back to this group and say something like:My job is to measure blade parameters X,Y,Z to uncertainty such and such. As far as real metrology goes, you (or again, your company really) need to be sure that the equipment used for measurements is properly calibrated and that, at least in the electronics industry, means regular visits to a calibration facility and renewal of certification. So ask about that too.
