摘要:
A method of machining one or more tooth slots in a bevel gear-shaped workpiece (36) with a cup-shaped tool (24) having one or more stock removing surfaces. The method comprises indexing the workpiece (36) by rotation about a workpiece axis to bring one of the tooth slots to a final machining position (1). Simultaneously with at least a portion of the indexing, positioning the tool (24) to contact the workpiece to commence machining the slot and infeeding the tool during the indexing while moving the tool with the indexing workpiece to maintain the tool positioned in the slot. The infeeding, movement of the tool, and indexing continuing at least until the final machining position (1) is achieved.

摘要:
In the production of a crown wheel which can mesh with a cylindrical pinion if the axes of rotation of the crown wheel and the pinion are not parallel, the workpiece from which the crown wheel is produced and a generating tool rotate at a ratio in the speed of rotation which corresponds to the proportion of the number of passes of the tool and the number of teeth of the crown wheel to be produced, and the tool is brought into engagement with the workpiece and is moved in such a way along the workpiece in a direction parallel to the axis of rotation of the cylindrical pinion that the tool works the tooth flanks of the crown wheel to be produced. When the centre point of the tool is moved in a direction parallel to the axis of rotation of the cylindrical pinion which can mesh with the workpiece, and the teeth of which form an angle beta with the axis of rotation of the cylindrical pinion, the workpiece acquires an additional rotation which is proportional to the product of this movement and the tangent of the tooth angle beta of the cylindrical pinion. During this movement the angle between the axis of rotation of the tool and the plane through the axis of rotation of the cylindrical pinion parallel to the axis of rotation of the workpiece is constant.

The present invention relates to a tool for milling, a milling body and a method for milling. The milling tool comprises a milling body (11) and a plurality of cutting inserts (13, 13A, 13B). The milling body has fastening devices (12) such to hold the cutting inserts in a plurality of insert pockets (18) comprising at least one base surface (19, 19A, 19B). Each of said cutting inserts has at least one cutting edge. The tool has a rotational axis and a rotational direction (R), a feed direction (F) as well as an end surface (14). The milling tool (10) is provided to cut a work piece substantially in an axial direction (A) of the tool, which is substantially perpendicular to the feed direction (F).

A method for processing a screw rotor includes a step of rotating a blade holder 2 while shifting the blade holder 2 in X-axis, Y=axis, and Z-axis directions to form a groove on the outer surface of a rotating cylindrical workpiece 1 with a tool 3 using a processing apparatus having a bed 11; a C-axis shaft supporter 12 disposed on the bed 11; a C-axis shaft 14 held by the C-axis shaft supporter 12, the C-axis shaft 14 for rotating the cylindrical object 1; a column 13 disposed on the bed 11; the blade holder 2 rotatably held by the column 13; and the tool 3 attached to the blade holder 2.
摘要:
A method of processing a screw rotor, where a screw groove is formed by a tool (3) in the outer diameter portion of a rotating object (1) to be processed. The processing is made using a processing device by swinging a tool post (2) and moving it in the X axis, Y axis, and Z axis directions. The processing device has a bed (11), a C-axis headstock (12) provided on the bed (11), a C-axis main spindle (14) supported by the C-axis headstock (12) and rotating the object (1) to be processed having a hollow-cylindrical shape, a column (13) provided on the bed (11), the tool post (2) swingably supported by the column (13), and the tool (3) attached to the tool post (2).

In the production of a crown wheel which can mesh with a cylindrical pinion if the axes of rotation of the crown wheel and the pinion are not parallel, the workpiece from which the crown wheel is produced and a generating tool rotate at a ratio in the speed of rotation which corresponds to the proportion of the number of passes of the tool and the number of teeth of the crown wheel to be produced, and the tool is brought into engagement with the workpiece and is moved in such a way along the workpiece in a direction parallel to the axis of rotation of the cylindrical pinion that the tool works the tooth flanks of the crown wheel to be produced. When the centre point of the tool is moved in a direction parallel to the axis of rotation of the cylindrical pinion which can mesh with the workpiece, and the teeth of which form an angle β with the axis of rotation of the cylindrical pinion, the workpiece acquires an additional rotation which is proportional to the product of this movement and the tangent of the tooth angle β of the cylindrical pinion. During this movement the angle between the axis of rotation of the tool and the plane through the axis of rotation of the cylindrical pinion parallel to the axis of rotation of the workpiece is constant.
