Abstract
A method of controlling a comb-cutter lathe in which one face of a tool rest (TBS) is provided with two or more juxtaposed tools (TL1, TL2) for subjecting a workpiece (WK) to machining by using: (1) predetermined tools in succession, (2) part dimensions, (3) a tool selection sequence, (4) a machining start location for each tool, and (5) mounting dimension information measured from a reference point on the tool rest to a distal end of each tool. Machining is sequentially performed based on this information by predetermined tools at machining locations (P.sub.5 -P.sub.4 -P.sub.3 -P.sub.2 -P.sub.1 ; P.sub.6 -P.sub.7 -P.sub.8 -P.sub.9 -P.sub.10) assigned to the tools, and after machining is completed by a first tool (TL1), the tool rest (TBS) is moved to position the next tool (TL2) at a machining location and machining is performed by that tool. The method includes moving the tool rest along a Z axis to a point P.sub.r at which none of the tools (TL1, TL2) will contact the workpiece (WK) when the tool rest (TBS) is moved in a direction (X-axis direction) at right angles to the longitudinal direction (Z-axis direction) of the workpiece, and thereafter moving the tool rest along the X axis to a point P.sub.t at which an X-axis position of a selected tool coincides with an X-axis coordinate value of a position at which machining is to be started by the selected tool, and thenforth performing machining using the selected tool.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
