When using polar coordinates, a ruler and protractor may be used to find estimated numbers, but geometry and trigonometry are used to find the precise points needed for accurate CNC cuts. G & M codes are written in lines of code that are formatted for specific machines.

Morphology
The parts give helpful cues: 'coordinate' signals a numeric value for position and 'polar' indicates relation to a pole or polar system, so a learner can infer this is a coordinate expressed with respect to a pole. However, the precise idea that it consists of two values (radius and angle) and the exact geometric interpretation are technical and not fully predictable from the constituents alone, making the term only partially transparent to a B1 learner.
Etymology
The term polar coordinate comes from a simple picture: the word polar points to a fixed 'pole' like the North Pole at the centre, and the word coordinate is the value that shows how far and which way a point is from that pole. So the two values, the 'distance' and the 'angle', together tell exactly where the point is.
