Description: |
| Claim:
The present invention relates to gear shaping machines and equivalent machine tools of the type in which a cutter is carried by a reciprocative and rotatable spindle and is caused to act on the workpiece by endwise movements of the spindle in one direction, and is returned, without performing any cutting action, by endwise movements of the spindle in the opposite direction. It is more particularly concerned with means or provisions for relieving the cutter, that is, effecting a relative separation between the cutter and work piece, after each cutting stroke so that it will not rub on the workpiece during the return stroke, and replacing it in the line of cutting travel before each cutting stroke. Its object is to reduce to the minimum the total mass of the parts needing to be thus displaced in order to relieve the cutter and restore the working relationship between the cutter and work, to effect the movements of relief and restoration quickly and efficiently with the minimum of shock and vibration, and to control, and alter as needed for work pieces of different types, the direction in which the relief movements take place. |
