摘要： A translation/rotation error compensation amount creating device creates, for a multi-axis machining apparatus having two rotation axes, a translation error compensation amount and a rotation error compensation amount both depending on the rotation axes. The translation/rotation error compensation amount creating device calculates the translation error compensation amount and the rotation error compensation amount based on an assembly error (set value) including at least an assembly error in a table surface or an assembly error in a spindle turning centerline in a multi-axis machining apparatus as well as the positions of the two rotation axes, and inputs the calculated error compensation amounts to a numerical controller controlling the multi-axis machining apparatus.

摘要： A CAD/CAM-CNC integrated system, configured with devices related to processes from design of a product to machining and including CAD, CAM and a CNC machine tool, has a shared database that stores information collected during machining or a change made to a machining command by an operator in association with structured information of the machining command. The information collected from a machining site is fed back to the CAM via the shared database, and the fed back information is analyzed to update the machining technique information, thereby making it easy to make use of the know-how accumulated in the machining site.

摘要： A controller includes a reference-sphere position obtaining unit that obtains coordinate values, on three linear axes, of a reference sphere placed on a table. The coordinate values are measured by controlling the three linear axes while a target rotation axis for which rotation axis center position is to be measured is positioned at three or more locations. The controller includes a rotation-axis commanded-angle obtaining unit that obtains commanded angles given to the target rotation axis during obtainment of a position of the reference sphere. The controller includes an approximate circle calculating unit that calculates an approximate circle passing near the coordinate values of the reference sphere on the three linear axes under a constraint of the commanded angles. The controller includes a rotation axis position storage unit that stores a center position of the approximate circle as coordinates of a center position of the target rotation axis.

摘要： Provided is a tool-path generating device that includes a point-sequence generating unit that generates a point sequence that represents a tool path on the basis of a machining program, and a smoothing unit that smooths the generated point sequence. The smoothing unit includes a filter-length setting unit that sets filter lengths that are applied to the points such that a pre/post-smoothing divergence amount of each point in the point sequence is equal to or less than a first threshold, a filter-length changing unit that changes the set filter lengths such that an absolute value of a difference between the filter lengths applied to adjacent points in the point sequence is equal to or less than a second threshold, and a filter processing unit that performs filter processing on the basis of the changed filter lengths.
