: Accuracy is the degree to which a measurement matches the "true" value, whereas precision refers to the consistency or repeatability of measurements over time.

m. Unlike general manufacturing, precision engineering prioritizes and determinism —the philosophy that machine behavior is governed by physics and is therefore predictable and controllable.

Precision engineering encompasses microtechnology and nanotechnology, where dimensions are measured on the micrometer and nanometer scales.

Precision engineering is a multidisciplinary field focused on the design and manufacture of high-accuracy systems and components, typically aiming for tolerances and positioning resolutions smaller than 0.1
