30 classic special-shaped parts machining principles-2

11.Making sphere on a milling machine 1

The workpiece is clamped on the chuck of the indexing head and rotated by hand. The tool is clamped to a mandrel that allows it to be radially adjusted.

12.Making sphere on a milling machine 2

Machining convex asymmetric sphere surfaces. The workpiece is clamped on the chuck of the indexing head and rotated by hand. The tool is clamped to a mandrel that allows it to be radially adjusted. The workpiece axis and the mandrel must intersect. The tool point position associated with the workpiece determines the dimension of the machined sphere surface.

13.Making sphere on a milling machine 3

Machining the surface of a concave sphere. The workpiece is clamped on the chuck of the indexing head and rotated by hand. The tool is clamped to a mandrel that allows it to be radially adjusted. The workpiece axis and the mandrel must intersect. The tool point position associated with the workpiece determines the dimension of the machined sphere surface.

14.Milling square with Reuleaux polygon

15.Milling triangle with Reuleaux polygon

16.Milling hexagon with Reuleaux polygon

17.Milling profile 1

Eccentric pink axis input. The red cutter milling the outline on the yellow workpiece, which is fixed to the grey gear shaft. The pink pulley to the gray gear shaft has a transmission ratio of 6, so the star profile created has 6 wings. The wings are not symmetrical due to the irregular rotation of the grey gear shaft. The profile shape depends on the relative position of the cutter and the workpiece. The black belt represents the toothed belt. It is better to use chain drive instead of belt drive.

18.Loci in Epicyclic gearing B5

A device for milling pentagons. R: Fixed the pitch circle radius of the green sun wheel. R: The pitch circle radius of the yellow planetary gear.K=R/ R =5. In order to obtain a rounded pentagonal trajectory, the distance between the red tool shaft and the solar wheel shaft is (8/30) R.Pink disk input.

19.Device for milling Archimedean spiral groove

Combination of bevel gear satellite drive and nut – screw drive.
