20140195037 | NUMERICAL CONTROL DEVICE - A numerical control device includes: a path local filter which locally interpolates an interpolation interval among a tool path so that a variation in a differential value at an interpolation object point becomes a continuous variation and a pulse interpolation unit which derives a reference time which proceeds per reference unit time which is shortened or extended corresponding to a deceleration instruction or an acceleration instruction according to a special command. The device obtains, from an intervening variable time function, an intervening variable at each time point at every reference unit time of the derived reference time, obtains a position coordinate on each transfer axis, with the position coordinate corresponding to the intervening variable at each obtained time point, obtains a transfer amount of a support in each transfer axis direction from the obtained position coordinate, and sets the transfer amount per reference unit time as a command pulse. | 07-10-2014 |
20140172153 | NUMERICAL CONTROL DEVICE - In a numerical control device, with respect to an intervening variable within a posture adjustment interval, the transfer command derivation unit obtains a position coordinate of a tip point on a tip path corresponding to the intervening variable and a position coordinate of a midair point on a midair path corresponding to the intervening variable, adjusts the obtained position coordinate of the midair point so that a variation in a direction of a projection tool axis vector becomes more gradual, and obtains a tool axis vector extending from the obtained tip point to the adjusted midair point, while with respect to an intervening variable outside of the posture adjustment interval, the transfer command derivation unit obtains a position coordinate of the tip point corresponding to the intervening variable and a tool axis vector extending from the tip point toward the midair point corresponding to the intervening variable. | 06-19-2014 |
20140156052 | NUMERICAL CONTROL DEVICE - A numerical control device includes a pulse interpolation unit. The pulse interpolation unit obtains an intervening variable at each time point based on an intervening variable time function, obtains a position coordinate of a post-interpolation tool path in the workpiece coordinate system and a position coordinate of a post-interpolation second transfer axis path on a second transfer axis which correspond to the obtained intervening variable at each time point, and obtains a position coordinate on each transfer axis corresponding to the position coordinate of the post-interpolation tool path in the workpiece coordinate system at each time point based on a specific relational expression using the obtained position coordinate on the second transfer axis as a constraint and representing a correlation between a position coordinate of a tool in the workpiece coordinate system and a position coordinate on each transfer axis. | 06-05-2014 |
20140114622 | ROUTE COMPUTING METHOD OF PREPREG TAPE - A route computing method for adhering and laminating a prepreg tape is disclosed. In an exploring vector computing step, an exploring vector along the expected direction of adhesion of the prepreg tape on the plane of the prepreg tape is computed, the exploring vector serving as a scalar of a predetermined quantity of small amount. In a foot computing step, the foot of a perpendicular line leading from an end point of the computed exploring vector to the plane is computed. A new exploring vector is computed based on the starting point of the exploring vector and the foot of the perpendicular line until a predetermined termination condition is realized. In navigating steps, the exploring vector computing step is repeatedly executed based on the new exploring vector with the foot of the perpendicular line serving as the initial point of the next computing. | 04-24-2014 |
20130123968 | NUMERICAL CONTROL APPARATUS - Disclosed is a numerical control apparatus including: a computing unit which calculates, based on a processing path, a moving distance of each support in a corresponding movement axis direction per set unit time; and a drive control unit which causes each driving device to transfer the support corresponding to that driving device in accordance with the moving distance of each support calculated by the computing unit. In response to input of a special command to a special command input device, the computing unit changes a length of the set unit time from a length in the state immediately before the input of the special command to a length corresponding to a velocity change instructed by the special command, and calculates, based on the processing path, the moving distance of each support in the corresponding movement axis direction per set unit time of which length has been changed. | 05-16-2013 |

20110153057 | NUMERICAL CONTROL DEVICE FOR TOOL MACHINE - A numerical control device includes a primary distribution pulse calculator that calculates primary distribution pulses obtained by distributing movement amounts in first and second directions included in a movement command of a work or a tool for each of predetermined calculation cycles. A secondary distribution pulse calculator calculates, for each movement direction, secondary distribution pulses obtained by distributing the primary distribution pulses of each calculation cycle calculated by the primary distribution pulse calculator, before and after corresponding calculation cycles within ranges of distribution sections across the corresponding calculation cycles and having an acceleration-deceleration time constant of the corresponding movement direction as a section width, and then accumulating the primary distribution pulses for each calculation cycle. A drive controller drives at least one of a tool moving device and a work moving device on the basis of the secondary distribution pulses calculated by the secondary distribution pulse calculator unit. | 06-23-2011 |
