摘要:
A numerical control method capable of machining a work with a required accuracy at high speeds. After the start of pulse distribution, it is discriminated (S12, S13) whether both a block being executed in an NC program and the next block both include feed instructions, and imposition values (A, B) corresponding to the discriminated result are stored in a register (C) (S14, S15). When a deviation (epsilonx, epsilony, epsilonz) between a desired amount of movement and an actual amount of movement becomes smaller than a register value (C) in relation to the three control axes, the control of positioning for the block is finished and the execution of the next block is started (S10).
摘要:
A numerical controller for a grinding machine, wherein one of reference sizing points is selected according to the contents of a numerical control program. Measured analog data indicating the diameter of a workpiece is received continuously to determine if the size of the machined workpiece coincides with the selected reference sizing point. Upon the coincidence of the size of the machined workpiece with the reference sizing point, a sizing signal is provided, and then machining control is changed in response to the sizing signal. An analog signal provided by a measuring device is sampled at a predetermined interval in a predetermined time. The analog signal is tested to see if the analog signal is in a predetermined range, which is decided based upon temperature variation or vibrations of the grinding machine. And the result of test is displayed to facilitate checking the output characteristics of the measuring device. The analog signal is compared with a predetermined reference value, and then the result of comparison is displayed together with a predetermined reference value.

After the start of pulse distribution, it is discriminated (S12, S13) whether both a block being executed in an NC program and the next block both include feed instructions, and imposition values (A, B) corresponding to the discriminated result are stored in a register (C) (514, S15). When a deviation (ex, ∈y, ez) between a desired amount of movement and an actual amount of movement becomes smaller than a register value (C) in relation to the three control axes, the control of positioning for the block is finished and the execution of the next block is started (S10).
摘要:
An automatic programming system is incorporated in a numerical controller which controls the operation of a machine tool connected thereto in accordance with a numerical control program. The programming system is designed to automatically program the numerical control program based upon machining information which is manually input by means of a data input device in an interactive mode for defining machinings to be effected on a workpiece. The programming apparatus includes means for automatically determining the machining order of a plurality of machinings on a workpiece in such a manner that any machining needing a higher accuracy is carried out later than any other machining needing a lower accuracy.

Bei einem Verfahren zur Ermittlung einer von einer Soll-Lage (Sa-c) abweichenden Toleranzlage (T a-c ) eines Aufnahmepunktes (6) eines in einer Anlage (2) ruhenden, von einem Transportmittel (8) aufzunehmenden Objektes (4a-c): - wird am Objekt (4a-c) eine Kennmarke (14a-c) in einer bekannten Relativposition (R a-c ) zum Aufnahmepunkt (6) angebracht, - ermittelt eine Recheneinrichtung (18) anhand einer in der Anlage (2) angeordneten Ortungsvorrichtung (16) eine Raumlage (L a-c ) der Kennmarke (14a-c) in der Anlage (2), - ermittelt die Recheneinrichtung (18) die Toleranzlage (T a-c ) aus der Raumlage (L a-c ) und der Relativposition (R). Eine entsprechende Vorrichtung enthält eine entsprechende Kennmarke (14a-c) und eine entsprechende Recheneinrichtung (18).
摘要:
The invention relates to a method for machining a contour on at least one workpiece, particularly for welding or sealing a seam between two workpieces, particularly between two body components, by means of a robot, characterized by the following process steps: positioning the workpiece to be machined at the robot and/or determining the actual position of the workpiece, determining the real path of the contour on the workpiece at the predetermined or other points by means of at least one sensor, actuating the robot corresponding to the individual vectors for correcting the motion of the robot while machining the contour.

This invention relates to a method for surface notching with a combination lathe. A finishing allowance (TC) and a work passage (15) spaced apart from a work passage by an offset quantity (R) are calculated to execute rough working (2) and thereafter the finishing allowance (TC) is finished with the same tool. In this manner the surface notching can be accomplished with a high accuracy.
