OK, here is an experiment for you: turn a piece of steel to exactly 1.0000", leave it in the garage for a few hours and measure it (down to tenths). Write down your number. Now put down the micrometer and warm up the pin in your hand for a few minutes. Measure again. Write down the number. Compare two numbers (and compare them to the 1.0000" you turned the part to in the first place).If you happen to have two micrometers that can measure don't to tents, try to compare the measurements you get from them as well.No, you don't need a temp controlled shop. My lathe or material is not going to see that much temperature swing during operation regardless of what temp it starts at (winter or summer). The DRO measures distance traveled from a point you select, for example the point at which you just contact a round bar with your cutter, and from there only reports how far you have traveled from that point. There is no fixed point reference from which all measurements are taken.
I can hold tenths tolerance on a part regardless of how chilly or warm my machine is.
Let me know what you find out
