(design engineering)
One of a number of equally spaced keys cut integral with a shaft, or similarly, keyways in a hubbed part; the mated pair permits the transmission of rotation or translatory motion along the axis of the shaft.
A strip of wood, metal, or plastic.
(graphic arts)
A flexible strip used in drawing curves.
A function used to approximate a specified function on an interval, consisting of pieces which are defined uniquely on a set of subintervals, usually as polynomials or some other simple form, and which match up with each other and the prescribed function at the end points of the subintervals with a sufficiently high degree of accuracy.


A thin flat piece of wood used between two pieces of heavy subflooring, taking the place of a tongue-and-groove joint; also used as a means of stiffening a miter joint.

spline, false tongue, feather, slip feather, slip tongue

spline, 2
spline, 1
1. A long thin strip of wood or metal which is inserted in a slot formed by two members, each of which is grooved and butted against the other.
2. In a suspended acoustical ceiling, a strip of metal or hard fiber inserted in the slot between adjacent acoustical tiles which butt against each other, forming a concealed mechanical joint.


In computer graphics, a smooth curve that runs through a series of given points. The term is often used to refer to any curve, because long before computers, a spline was a flat, pliable strip of wood or metal that was bent into a desired shape for drawing curves on paper. See Bezier and B-spline.

Choosing a second plane spline curve [[gamma].sub.i] = [Z.sub.i](y) perpendicular on the plane of [c.sub.i] = [Z.sub.i](x) and having common loops so that the arc of curve projections [s.sub.i](y), which belong to the curve [[gamma].sub.i], on the plane z = 0 (level plan) must be also equidistant from the length [h.sub.y], a rectangular spatial equidistant network with common nodes can be formed, respectively a spline bicubic surface (Fig.
