摘要： If the angle α formed between the interpolated cutting surface perpendicular direction vector (It, Jt, Kt) and the interpolated tool direction vector (Ttx, Tty, Ttz) becomes smaller, movement of a tool becomes unstable. In this case, the tool diameter compensation vector (TCx, TCy, TCz) is set to the tool diameter compensation vector calculated in the immediately previous interpolation cycle, thereby preventing unstable movement. Further, in case of a block instruction where a distance between positions in cutting point instructions is large whereas distance of movement of linear axis control point is small, an excessive cutting may occur. To deal with this problem, movement of linear axis control point in a current block is stopped or converted into linear movement so as to prevent a loop-shaped movement of the linear axis control point.

摘要： The invention provides a method of generating a smooth curve from a commanded sequence of points by a numerical controller for a multi-axis machine tool having three linear axes and two or more rotary axes to perform interpolation along the curve. Corrected command points are obtained for linear axes and for rotary axes, respectively. Components of corrected command points for linear axes and corrected command points for rotary axes are synthesized with each other so as to obtain a synthesized corrected command point. And a curve passing through the synthesized corrected command points is generated to perform interpolation. As a result, curve interpolation which is more appropriate than that in a multi-axis machine tool having two or more rotary axes can be performed.

摘要： The shapes of machine parts for which the possibility of interference exists are defined as rectangular parallelepipeds and it is judged whether or not there is interference between a first rectangular parallelepiped of a first machine part and a second rectangular parallelepiped of a second machine part. The method involves rotating the first rectangular parallelepiped and second rectangular parallelepiped so that each side of the first rectangular parallelepiped lies parallel to each axis of the reference coordinate system. Interference is thus judged based on whether any vertex of the second rectangular parallelepiped exists within the first rectangular parallelepiped. Likewise, interference is judged depending on whether any vertex of the first rectangular parallelepiped exists within the second rectangular parallelepiped. Further, interference between the respective sides of the first rectangular parallelepiped and second rectangular parallelepiped is judged through division into the planes X-Y, Y-Z, and Z-X. When it is judged that interference exists in all planes, it is judged that there will be interference between the first rectangular parallelepiped and second rectangular parallelepiped.

摘要： A controller that eliminates an error caused by acceleration/deceleration control, and controls the velocity of drive axes which is not represented by a rectangular coordinate system such that maximum allowable values of velocity, acceleration, and jerk of the drive axes are not exceeded. A program is analyzed in a command analysis section, and an interpolated position on a motion path in the rectangular coordinate system is determined in a first interpolation section, and then converted by means of a transformation section into drive axes' positions not in the rectangular coordinate system. In a tangential acceleration calculating section, a tangential acceleration is determined. In a velocity limit calculating section, a velocity limit at the time of each position being reached is determined which does not exceed maximum allowable values of velocity, acceleration, and jerk of the drive axes. A deceleration target velocity at the time of each position being reached is determined in a deceleration target velocity calculating section. An intermediate memory stores the calculated results. A motion amount for a processing period of a second interpolation section is determined in an acceleration/deceleration processing section, and is interpolated in the second interpolation section, to be output to a servo control section for the drive axes. By performing the acceleration/deceleration processing before the second interpolation, a trajectory error is eliminated.

摘要： A numerical controller controlling a 5-axis machine tool compensates setting error that arises when a workpiece is set on the table. Error in the three linear axes and the two rotation axes are compensated using preset error amounts to keep the calculated tool position and tool direction in a command coordinate system. If a trigonometric function used for error compensation has a plurality of solution sets, the solution set closest to the tool direction in the command coordinate system is selected from the plurality of solution sets and used as the positions of the two rotation axes compensated in the above error compensation.

摘要： A numerical controller configured to enable machining of a conical surface such that vectors at a start point, an end point, and an interpolation point of a circular arc and their extensions never cross one another. Normal direction vectors Vnors and Vnore, tangential direction vectors Vtans and Vtane, and tool posture vectors Vts and Vte at the starting and end points are obtained based on programmed positions PA′ and PB′ of the starting and end points, a circle center position, and rotational positions of two rotary axes. Based on these vectors, tangential direction angles as and ae and the normal direction angles bs and be with respect to tool postures at the starting and end points are obtained. Normal and tangential direction vectors Vnori and Vtani and angles ai and bi at the interpolation point are obtained by interpolating the normal and tangential direction vectors and angles at the starting and end points, whereby a tool posture vector Vti at the interpolation point is obtained. The rotational positions of the rotary axes and positions of linear axes are obtained based on the tool posture vector Vti at the interpolation point. Circular machining can be also performed for a three-dimensional programmed circular arc.

摘要： A work is installed on a table of a machine tool, and the coordinate system on the work is (X′, Y′, Z′). Each three points on respective three faces of the work, which are orthogonal to one another, A, B, C, D, E, F, G, H and I, are detected with a touch probe. From three points on the same plane, each of three formulas of planes which lies on the three points, respectively, are obtained. A position O′ (XO, YO, ZO) of a point where the three plane intersect with one another is obtained. This position is a parallel translation error. From these three plane formulas, points on the X′, Y′ and Z′ axes each being distant from the position O′ by the length L are obtained. Rotation matrices are obtained from the respective points, position O′ (XO, YO, ZO), and L. Rotary direction errors are obtained using the rotation matrices. In this manner, a work location error which is composed of the three-dimensional parallel translation error and three-dimensional rotary direction errors is obtained.
