摘要： A machining control device controls spindle rotational speed. A set of stability limit curve data is stored indicating a relation between a spindle rotational speed and a limit cutting-in amount whereby chatter vibrations are inhibited. Spindle rotational speed and tool cutting-in amount in starting machining are set based on the data. Vibrations of the spindle are detected during cutting. Whether chatter vibrations have occurred is determined based on vibrations detection. Spindle rotational speed is controlled with reference to the data to inhibit chatter vibrations. Cutting-in amount in starting machining is set to be less than a maximum cutting-in amount within a stable region of the data, and spindle rotational speed in starting machining is set to be less than a rotational speed when the cutting-in amount is maximum within the stable region. Spindle rotational speed is increased by an amount of a predetermined rotational speed when chatter vibrations have occurred.

摘要： An automatic recognition method capable of accurately determining edges of a concavity or convexity in order to achieve an improved measuring accuracy in recognition of a concavity or convexity. This method comprises the steps of: converting a photographic image of an object having a concavity or convexity defined therein into data in a specified feature space; obtaining a plurality of points that exist outside a virtual circle determined by a virtual center of the concavity or convexity, the virtual center being established for each elementary area of the image converted into the feature space data; obtaining the equation of a plane that passes through the plurality of points; detecting symmetric pairs of pixels in each elementary area of the feature space data with respect to the corresponding virtual concavity or convexity center; and recognizing the position of the concavity or convexity of the object when the symmetric pixels satisfy the equation of the plane.
