摘要： A numerical control information generating apparatus has a function of automatically correcting machining conditions by calculating corrected machining conditions from corrected numerical control information. The apparatus also has a valid/invalid setting function of automatically correcting machining conditions for the purpose of allowing an operator to select at will the conditions under which the function of automatically correcting machining condition works, and a numerical control information correcting section, in which a machining conditions automatic correction command is provided, so as to perform machining conditions automatic correction at any time as required. As a result, since machining conditions are corrected automatically by correcting numerical control information, an operator can set proper machining conditions easily even if the operator does not understand the relationship between the machining conditions and the generated numericaL control information.

摘要： A numerical control information generating system prevents a tool from interfering with a work when the tool is moved from a tool change position to a cycle start point or from a cycle end point to the tool change position by setting a step start point and a step end point for each machining step outside of a before-machining shape, and classifying the positional relation of the shape upon completion of machining with the machining steps into the outer face, inner face, the front face, the outer rear face and the inner rear face so that based on the information denoting the positional relation the paths of the tool from the tool change position to the step start point or from the step end point to the tool change position are determined. When a same tool is used for machining in plural sequential steps, the time required to move the tool between the step to another can be shortened since the tool is moved from the end point of a step to the start point of the subsequent step.

摘要： In a numerical control system which controls the rotational angle of a spindle in a numerically controlled machine and tool in synchronism with the position of a feed axis based on a data table storing information for positional commands for the feed axis in correspondence with the rotational angle of the spindle, a universal purpose turning operation is effected at a higher efficiency by generating a marker pulse when a value set by counting the pulses in A- and B-phases from a spindle pulse generator has reached a pre-set value, and by controlling synchronization during synchronized operation, based on the marker pulse instead of the marker phase pulse from the spindle pulse generator.

摘要： When a position of a tool blade tip for displaying the work shape, tool shape and tool locus is calculated by an interpolation arithmetic operation based on the interpolation instruction and feed speed instruction within a numerical control data, the calculated position of the tool blade tip is compared with the display scope every time an interpolation arithmetic operation is conducted; a determination is made as to whether or not the tool shape and tool locus to be displayed are inside of the display scope, and when they exist outside, uses a higher speed as the feed speed for the interpolation arithmetic operation. Therefore, even when an operator tries to check numerical control data by reducing the display scope for local graphic display, the interpolation outside the display scope can be conducted at a higher speed to thereby allow the operator to check the numerical control data quickly and immediately.

摘要： A rotational position detecting apparatus detects the rotational position of a rotating object and compensates for an eccentricity of the rotating object. First and second sensors generate first and second detection signals having phases offset relative to each other. An error signal denoting the eccentricity of the rotating object is generated in accordance with a fluctuation of an amplitude signal corresponding to a difference between amplitudes of the first and second detection signals. The error signal is added to a position signal to obtain a eccentricity compensated rotational position detection signal.

摘要： In a position detecting apparatus, digital signals in the presence of excitation signals are corrected by digital signals in the absence of excitation signals which are off-set values generated by each components of this postiion detecting apparatus. It therefore eliminates troublesome adjustment by variable resistors, and achieves precise position detection at any time without errors. Furthermore, since signals in the direction opposite to exciting signals are applied to the resolver upon the completion of excitation, the output of the resolver quickly becomes stable in the non-excited state, and off-set values are measured at a high speed.

摘要： A method whereby the numerical control information preparing function determines the manner of machining. On the basis of the input shape of a workpiece and on the basis of the input shape of a component part to be obtained from the workpiece, a portion of the workpiece which is to be subjected to outer diameter machining and a portion of the same which is to be subjected to inner diameter machining are determined. Thereafter, a division candidate point is obtained so that each of the portions may be divided, at the division candidate point, into a sub-portion to be subjected to forward cutting and a sub-portion to be subjected to backward cutting. On the basis of the configuration of the backward cutting sub-portion and the shape of the tool to be used, a check is made as to whether any part of the sub-portion can remain uncut after the backward cutting. On the basis of the result of this check, a determination is made as to whether the entire portion should be divided at the division candidate point. If the division is determined, the portion is divided into the forward cutting sub-portion and the backward cutting sub-portion, with the division candidate point serving as the boundary. Thus, each of the outer diameter machining portion and the inner diameter machining portion can be divided into a forward cutting sub-portion and a backward cutting sub-portion at the optimum point.

摘要： A linear attuator of the present invention performs the fixing of a driving base by the primary fine means when the deflection of the moving velocity of the driving base in a driven direction and the moving velocity of the primary fine means driven by the secondary fine means in the driven direction becomes less than or equal to a specified allowable value, i.e., when the relating velocity becomes nearly zero, and moves the primary fine means driven by the secondary fine means in the direction opposite to that of the driven direction after not transferring the driving force of the secondary fine means to the driving base when the driving base is separated from the primary fine means. Thus, the driving base can be driven by a stroke longer than the driving stroke of the fine actuator itself at a specific velocity and it can be driven smoothly.

摘要： A numerical control apparatus is characterized by a structure in which: a machining program stores the final shape of a work as well as the shape of a material; designates the outermost point (an apex) on the work in a direction opposing a cutting direction as a cutting reference point; sets linear lines which are respectively lowered from the cutting reference point by cutting depths, and obtains the inter-sections of the lines and the material shape. The intersections thus obtained are classified into points where the tool enters the work zone and points where the tool emerges from the work zone, so that the tool can be moved at a predetermined cutting rate for a cutting operation between the point where it enters and the point where it emerges from the work zone while it is moved at a rapid traverse rate between the emerging point and the point where it re-enters the work zone. These operations are repeated until the tool touches the final machining shape, whereupon the tool is moved along the final machining shape at the predetermined cutting rate and cutting depth. In this manner, the cutting tool is prevented from idle operations in the feed zones where the material does not exist and the machining time can be reduced effectively.
