Description

Methods of continuous smooth-free milling of various toothed and schlintsev surfaces by profile milling cutters — snails are known.

There is also known a method of continuous smooth-free milling of right angle-heel roller shafts, and so on. Parts with ausun-1; kinematic connection between the rotation of the workpiece and the cutter with a continuous axial feed of the cutter.

However, the mills used in these methods have a complex structure that makes it difficult to manufacture the mills and increases their cost.

The described method eliminates the indicated disadvantages. This is achieved by the fact that the milling of the vadipa between the splines is performed mainly by the end teeth of a narrow disk cutter, which are cut into a part of its circumference with a radius exceeding the radius of its uncut part to the slot height.

To ensure the specified shape of the face of the roller contour during milling, the time of the working turn of the cut part of the cutter and the time of turning of its foam cut part are respectively equal to the time of turning the workpiece at the trough angle and the time of its turning at the spline angle.

On fkg. 1 shows the location of the cutter relative to the workpiece, top; in fig. 2 is a side view; in fig. 3-end view.

Double-sided disk milling cutter / fitted with teeth, cut only on the part of its circumference with a radius R, which exceeds the radius R of the non-cut part to the height L of the spline, and the bit of the cutter is made smaller than the width between the slots of the part.

When milling the spline shafts on a gear milling machine, workpiece 2, kinematically connected with a milling spindle, continuously breaks in the control of the cut end of the cutter, and the cutter performs axial mixing by a certain amount per one turn of the workpiece.

In this case, the tooth part of the cutter selects the material from the depression between the splines in an arc, llpii the cutter outlet to the lateral surface of the slot. After the node passes freely the node with the smooth part of the cutter. The ratio of the lengths for parszanio.n and the smooth parts of the cutters, as well as the kinematic connection between the cutter and the oi billet Roller rotation angle I1litz.

In this method, not the entire profile of the milling cutter participates in the cutting process, but only its frontal part, which significantly contributes to the design of the milling cutter, compared with the cutting edge of the milling cutter.
