Hello, I have just recently started my NC course. We have questions to work through but the way they are written I find hard to understand. I was hoping if someone could help answer or guide me in the right direction. I have 3 questions I need help with
Explain why it is important to use a fixed common reference point for dimensioning of drawings and sketches
Explain how to use other sources of information to support the data (such as electronic component pin configuration specifications, standard reference charts for limits and fits, tapping drill reference charts, bend allowances required for material thickness, electrical conditions required for specific welding electrodes, mixing ratios for bonding and finishing materials, metal finishing specifications and inspection requirements)
Describe the need to ensure that sketches are of a suitable size, use appropriate drawing conventions, are in proportion and are legible to others.
Thank you, any help is appreciated
