|
Production of a workpiece with circular cross-section at round woodturning A resting point, in the video the blue cutting edge, produces a circular cross-section on the moving workpiece |
|
Mechanism generating circular orbits The blue moving arm generates circular orbits relative to the fixed green component, e.g. as a basis for woodturning |
|
Mechanism generating concentric ellipses having a "double shutter" The blue arm generates mathematically exact ellipses by two turning points, which slide with the yellow and the red slider in a cruciform guideway of the green component, e.g. as a basis for woodturning |
|
Oval woodturning with the kinematic inversion "double loop" for producing an elliptical cross-section For moving you rotate with the lathe's spindle for example the red block around the fixed red pivot point. The red block transmits its rotation on the green clamping plate. The clamping plate turns and slides simultaneously with their cross-guide on the red and the yellow block back and forth. Thereby the cutting edge cuts exact ellipses into the workpiece. |
|
Production of a workpiece with elliptical cross-section at oval woodturning With slow rotation you can see that a once cut ellipse with its contour exactly slides along the cutting position, with which it was originally cut. This point remains at rest and exactly at that level, the turner has to position its cutting edge again, if he wants to cut deeper or wider in the radial direction in the longitudinal direction. |
|
Angular displacement of a cutting edge during rotation of the workpiece at oval woodturning As a kinematic characteristic of oval woodturning, the video shows how the rake angle and the clearance angle of an applied cutting edge change periodically during the circulation of the workpiece, and how cut ellipses get twisted relative to each other, if the cutting edge is not exactly lead to the spindle height. |
|
Cardan circles generating ellipses with a fixed gear at oval woodturning Production of exact ellipses with cardan circles according to the principle of the Italian Renaissance mathematician Gerolamo Cardano. It refers to two circles, one of which is exactly twice as large as the other, and where the smaller exactly rolls within the larger e.g. using a suitable gear. |
|
"Volmer tooth belt transmission" generating ellipses at oval woodturning Generation of exact ellipses with a tooth belt transmission according to Johannes Volmer. The orange, rectangular plate can be shifted within the brown guides relative to the round yellow disc. So you continuously change the spacing between the blue and light-violet pulley. This allows to set the slenderness of the generated ellipses as you wish, without having to change any gears (see cardan circles). |
