(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, 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.

If the trajectory, which must be travelled, is given by discrete points (loops), determined by measuring, one possibility is by interpolation of spline curves.
Thus, for solving this problem it has been started from the approximation of the surfaces using bicubic spline curves, which were mathematically determined the fact which allowed virtual representation of the surface with the aid of the Borland Delphi 7 software.

Using the points of the spline curves, was followed the contour of the pictures, trying to adjust the spline in such way that it will take the form of the model.
We mentioned the use of spline curves (B-spline) without mentioning the definition and their usage; thereof, curve splines such are interpolation curves controlled by points which are respect the condition and continuity of the curve.
