Is this sentence understood to mean: The allowable deviation range is 0~1.5mm, or the maximum deviation is 1.5mm? The key is "allowed". Is it necessary to change it to the maximum allowable deviation? Let’s see everyone’s understanding. There are many places that resemble the same value, as shown in the figure:
The meaning is not too different, it feels like they are all within a range of values ~ as long as it does not exceed this value, it meets this standard, right?
The allowable deviation is 1.5mm, and the deviation includes positive deviation and negative deviation, so the allowable deviation of 1.5mm should be understood as: Size -1.5 ~ Size +1.5 Personal understanding, welcome to correct me
The shape and position deviation can be written like this, and the size deviation must have a sign.
Such as this: The specific range is ±, or 0 to 1.
The deviation should be a range, then there should be an upper limit and a lower limit, and only one value is incomplete.
How do you understand this tolerance of 1mm?
