Abstract:
In a complex machining machine tool, a tool rest capable of attachably and detachably installing tool installing inserts thereon is provided, a plural number of virtual tools is set and registered concerning a predetermined at least one tool together with its indexing positional data in tool file, the tool data of the corresponding virtual tool is read out from the tool file on the basis of the machining instruction by the virtual tool stored in machining program, and the corresponding virtual tool is indexed on the tool rest on the basis of the indexing positional data, and then machining with the virtual tool is executed. At the time of machining, it is possible to continue machining with the same tool by only positional indexing without changing the tool. The work for changing tools can be extremely decreased even if machining contents are changed or it is necessary to change tools by tool exhaustion.
Abstract:
In a method of machining a workpiece wherein a complex tool 21 having a plurality of inserts 22, 23, 25, 26, 29, 30 thereon is installed on a tool holding means 20 of a machine tool so as to machine a workpiece 17, turning machining is performed on rotating workpiece, selectively using one or more inserts of a plurality of inserts installed on the complex tool, with the complex tool being fixed and held, and milling machining is performed on a workpiece using one or more inserts of a plurality of inserts installed on the complex tool, with the complex tool being rotated and driven. Then, both turning machining and milling machining can be performed without changing tool, and extremely efficient machining is possible.
Abstract:
The program for a numerical control device for controlling a numerically controlled lathe includes translation commands for translating the tool and the machining mode switching commands for switching between the normal mode by which only the tool is translated and the Swiss mode by which both the tool and the work are translated. A machining program analyzer unit analyses the program commands into translation commands and the machining mode switching commands. In response to the machining mode switching commands, the interpolation data generator unit converts the commands for translating the tool two-dimensionally into translation data for the tool along a first axis and a translation data for the work along a second axis. Thus, the programming for the machine tool capable of operating both in the normal and the Swiss mode is made easier.
Abstract:
A cutting unit and a grinding unit are aligned adjacently and adopt a common contour tracing means numerically controlled with respect to a X-Y plane coordinate system. A cutting tool and a grinding tool are provided on respective .theta.-axes along Z-direction and are commonly controlled about the .theta.-axes to direct in a tangential or a normal direction of the contour. The cutting and grinding tools are shiftable away from a reference point of the .theta.-axis to finely adjust a cutting line and a grinding edge outward/inward a reference contour.

Abstract:
A lathe capable of performing both usual machining and balance correction machining of a workpiece. In a combined machining lathe having a drilling and/or milling machine, vibration sensor(s) are attached to a headstock and/or a tailstock and a sensor for detecting a rotation angle of a main spindle is provided. After the usual machining, the workpiece is rotated at a predetermined rotating speed on the same lathe and an amount of imbalance and phase are calculated by a imbalance arithmetic unit. An NC machining program for balancing the workpiece is automatically produced by a balance correction machining program producer within a numerical controller and balance correction machining of the workpiece is carried out using a rotary tool such as a drill or the like.
Abstract:
A machine tool for machining rotating workpieces at high rotational speeds and, in particular, with multiple tool movements within a revolution of the workpiece, comprises a low-inertia high-torque motor having an output shaft and a tool holder mounted for movement relatively to the motor. A cam or other single element connection drivable connects the output shaft and the tool holder and the motor can be operated by control apparatus to so oscillate the output shaft that the tool is moved rapidly back and forth in phase with the output shaft oscillation and in correspondence with the rotation of the workpiece to perform required machining movements.
Abstract:
Automatic turret lathe with a synchronous spindle in the tool turret which is drivable in synchronism with the main spindle and comprises a workpiece chuck means. To enable workpieces to also be worked on the rear side, i.e., on the side on which they were severed from a stock rod, while the next workpiece held in the main spindle is already being machined with the aid of a further tool carrier, a third tool carrier is arranged on the side of the tool turret mounted on a compound slide system facing away from the main spindle.
Abstract:
Eleven embodiments of machine tool particularly intended for data-control are disclosed. A rotating workpiece is moved in relation to a lathe tool which is stationary during cutting. Tools such as drills are also provided for working on the end face of the workpiece. In some embodiments the workpiece is movable in two directions mutually perpendicular to its rotational axis as well as along that axis. In some embodiments the machine may act as a milling, drilling or boring machine as well as a lathe. In some embodiments the rotatable workpiece holder may be replaced by a tool holder.
