    摘要: A spline interpolation method of subjecting given points to interpolation by using a cubic spline curve is provided. A first-derivative vector is derived from a preset number of points including a starting point (P.sub.1), and a cubic equation between the starting point and a next point is derived based on the coordinate values of the preset points including the starting point (P.sub.1) and the extreme point condition of the starting point (P.sub.1), to derive a spline curve between the starting point (P.sub.1) and a point (P.sub.2) next to the starting point (P.sub.1). Next, the first-derivative vector at P.sub.2 and a new next point are used instead of the starting point (P.sub.1), to derive a cubic curve between P.sub.2 and P.sub.3. In this way, a cubic equation between points is sequentially derived to obtain a cubic spline curve, and as a result, a spline curve posing no practical problems can be obtained without previously receiving all of the sequential points, while sequentially receiving the sequential points in a forward direction.

    摘要: Expert knowledge regarding investigation of the causes of various failures, and knowledge for extracting DI/DO information (IOD), which is exchanged by an NC unit (11) and a machine tool (13), as well as information (ITD) internally of the NC unit, is stored in a knowledge base (IB). When the contents of a failure are entered from an alarm detector (11g) upon occurrence of the failure, a reasoning mechanism (ADPR) uses the expert knowledge conforming to the failure to automatically extract the DI/DO information and information internally of the NC unit (IOD, ITB), ascertains actually occurring phenomena based on this information, recognizes the cause of the failure from these pheonomena, and displays the cause of the failure and a method of dealing with it.

    摘要: A tapping control apparatus effects tapping operation by synchronizing the rotation of a spindle and the movement along a Z-axis through pulse distribution. The tapping control apparatus has a time constant determining unit (2) for determining a time constant according to a command speed for the spindle. The determined time constant is given to an acceleration/deceleration control circuit (10, 20) for performing tapping operation. Since a time constant is selected according to the rotational speed of the spindle, the time constant can be large to prevent overshooting or the like when the rotational speed of the spindle can be high, and the time constant is small for higher-speed machining operation when the rotational speed of the spindle is low.

    摘要: The rotating direction of a spindle is stored in a tool data file storage area (101b) for each and every tool used.Data necessary for creating an NC program are stored in a RAM (105) conversationally using an operator's panel (108) and graphic display unit (102). Thereafter, a processor (103) creates the NC program using the data stored in the RAM.When a tool used in a predetermined machining process is decided during the creation of the NC program, a tool selection command for selecting the tool is outputted and, in addition thereto, a spindle rotating direction conforming to the selected tool is obtained from the tool data file storage area (101b) and a spindle rotating command for rotating the spindle in said direction is outputted.

    摘要: A picture producing apparatus forms a picture comprising a plurality of picture elements with different light-reflecting properties providing different optical reflection densities using a plurality of dot forming units to provide dots of recording materials of different concentrations. The optical reflection density range of an entire original picture to be reproduced is determined and selecting circuitry responsive to that determination selects at least one of the dot forming units to form picture elements reproducing the original picture. The dot forming units vary the areas of the picture elements formed by the dots so as to represent in the reproduced picture the optical reflection density range of the original.

    摘要: An image signal processing apparatus has a color decorder for preparing a histogram for the brightness level of each color signal of an input image signal such as an NTSC signal, and an image process circuit for calculating a cumulative brightness distribution curve of the histogram and for performing gamma-correction of the input image signal in accordance with the cumulative brightness distribution curve. A CPU in the image process circuit can calculate upper and/or lower extremities of each cumulative distribution curve and perform normalization of each color signal within the range defined by the calculated upper and/or lower extremity.

    摘要: First and second tool control blocks respectively precede and follow a corner on a tool path. A pulse distribution computation based on NC command data in the second block is not executed at the instant that a pulse distribution computation based on NC command data in the first block ends. Rather, a pulse distribution computation based on the NC command data in the second block is performed starting at the instant that a feed speed based on the NC command data in the first block is reduced to a prescribed speed by being decelerated. As a result, the torch of a gas cutting machine or the like will cut the corner portion quickly with a high degree of accuracy and without cutting the corner to an overly rounded shape.

    摘要: The present invention pertains to improvements in signal transmitting and receiving equipment for transmitting and receiving signals regarding the M, S and T functions between a numerical controller and a machine tool. Numeric codes (c.sub.l to c.sub.n) that are sent from the NC apparatus to the machine tool are added or combined with a redundant signal (pt) for checking the validity thereof. Only when it is decided that the received codes are valid, based on the added signals, is the machine tool operated. With such an arrangement, even if a parallel transmission system using many signal lines is employed it is possible to offer an NC machine tool which is capable of preventing erroneous operations related to the M, S and T functions, and hence the NC machine tool has high reliability.
