    摘要: Preregistered in a memory (103) as conversion tables for storing NC data of a first type into NC data of a second type are a G-code conversion table (GTB) giving the correlation between G codes of the first NC data and G codes of the second NC data, and M-code conversion table (MTB) giving the correlation between M codes of the first NC data and M codes of the second NC data, and a coordinate command code conversion table (PTB) giving the correlation between coordinate command codes (X, Y, Z, I, J, K codes) of the first NC data and second NC data. The format of the first NC data is changed to the format of the second NC data by making use of these conversion tables (GTB, MTB, PTB).

    摘要: An NC data creation method in an automatic programming apparatus in which NC data are created for moving a tool, after the tool has completed the machining of a first area (AR1), to a second area (AR2) to perform predetermined machining at the second area. The method includes checking whether an auxiliary position input mode has been set. If auxiliary position input mode has not been set, then temporarily haling automatic creation of NC data, thereafter inputting auxiliary positions (PA1, PA2) conversationally, and creating NC data for moving the tool to the second area via the inputted auxiliary positions.

    摘要: A machining process determination method in automatic programming for automatically creating NC data for a lathe. The method includes storing machining processes in a memory in a machining sequence, reading the previously stored machining processes out of the memory in order after entry of a blank profile (BP) and part profile (PF); automatically discriminating based on the blank profile and final part profile whether the read machining process is needed to obtain a final part; when it is not required, performing identical discrimination processing upon reading the next machining process out of the memory, and when it is required, determining a cutting domain (A1, A2, A3) and cutting direction of the machining process; and thereafter creating NC data upon reading subsequent machining processes out of the memory and performing identical processing.

    摘要: A method of machining performed by back-and-forth cutting, particularly a machining method for automatically creating a pick-feed path that will not cause a tool (TL) to interfere with a workpiece (WK) when a pick-feed is performed, moving the tool along the pick-feed path, and thereafter performing cutting. If the workpiece is concave in the proximity of the pick-feed path, the method includes obtaining an approach plane (AP) containing a machining end point (Pe) and lying parallel to a plane (PL) which contacts a curve (OLC) of the external shape of the workpiece at a next machining starting point Ps. Then a point of intersection Pc between the approach plane (AP) and a straight line (SL) passing through the machining starting point Ps is obtained, with the straight line coinciding with the direction of the central axis of the tool at the machining starting point. The path Pe.fwdarw.Pc.fwdarw.Ps serves as the pick-feed path. If the workpiece is convex in the proximity of the pick-feed path, the method includes obtaining the approach plane (AP) contacting the curve (OLC) of the external shape of the workpiece at the next machining starting point Ps. Then the point of intersection Pc between the approach plane (AP) and a straight line (SL') passing through the machining end point Pe is obtained, with straight line coinciding with the direction of the central axis of the tool at the machining end point. The path Pe.fwdarw.Pc.fwdarw.Ps serves as the pick-feed path.

    摘要: The present invention relates to a tool radius compensation method for numerically controlled apparatus in which the coordinates Pi of the position of a tool center are computed which is offset a distance equal to the radius r of the tool in a direction normal to a surface to be cut based on commanded positional information P.sub.1, Pc and P.sub.2, for enabling the tool to three-dimensionally cut a workpiece. Based on the positional information P.sub.1, Pc and P.sub.2, a unit offset vector Vi is determined which lies on a plane defined by vectors U and V normal to first and second surfaces to be cut at a three-dimensional corner point Pc. Components along respective axes of the unit offset vector Vi are corrected so that the tool center will move smoothly along a curve contiguous to paths of movement of the tool center before and after the three-dimensional corner point Pc. The coordinates Pi of the position of the tool center are determined from the corrected unit offset vector Vi', a tool radius r, and the information Pc on the position of the three-dimensional corner point.

    摘要: A method and an apparatus for controlling spindle speed are disclosed. When the speed ranges of respective gear ranges are selected in advance so that speed ranges corresponding to neighboring gear ranges partially overlap one another, and the gear range conforming to the commanded spindle speed is selected for rotating the spindle at the commanded spindle speed, it is determined whether the commanded spindle speed belongs to the currently selected range, no gear change is made if the decision is affirmative, and the gear range to which the newly commanded spindle speed belongs is found if the decision is negative, the gear range being switched to the gear range thus found.
