Morphology
The noun combines 'plane' (a woodworking tool) with 'compass' (an instrument for drawing arcs), so a learner who knows both words can infer the tool has something to do with shaping or smoothing curves. However, the specific sense — a plane with a flexible/curved sole for concave or convex surfaces — is a technical extension not fully predictable from the constituents, making the meaning only partially transparent to B1 learners.
Etymology
Compass plane is named for how the tool works: compass brings to mind round curves and a plane is a smoothing tool, so its flexible bottom bends to follow a curve the way a compass draws a circle. That's why a compass plane is used to smooth 'concave or convex surfaces'.
