摘要： PURPOSE:To make interference checkable in a three-dimensional manner, by describing partial three-dimensional forms of a tool and a machine tool on a picture tube face-plate according to a tool shifting route, while checking the interference with a work with a visual point variable input. CONSTITUTION:Three-dimensional form 15 information on a work by a CAD system and three-dimensional form information on a tool shifting route 16 machining NC data and so on are described on a cathode-ray tube 13 for color pattern displaying via a controller 11, and furthermore partial three-dimensional forms 17 of a tool and a machine tool are described according to the tool shifting route 16. And, with information 18 of a positional attitude, a connecting positional direction, etc., of the tool and the machine tool to the tool shifting route 16, the tool form 17 is described as well, and three-dimensional positional attitude relations of the work and the tool as well as the machine tool to be secularly varied by operation of a disc 12 are displayed on a simulator while operating the desired visual point variation. Thus, interference of the tool and the machine with the work is surely preventable from occurring.

摘要： PROBLEM TO BE SOLVED: To reduce the burden of a designer by minimizing the number of tools which are used after the tool paths are set and also minimizing the changes of design of machining conditions, etc. SOLUTION: The balls A having their diameters equal to the constant depth of unmachined value are arranged on a machining object surface (final target shape) 64. Meanwhile, the balls B having diameters equal to the diameter of a hemispherical shape of the machining part of a machining tool are produced and placed so as to touch the largest distance points of balls A respectively. Then the balls A (black circles) crossing the balls B are displayed in images as the unmachined parts. As a result, the areas where the unmachined parts occur can be confirmed without setting the tool paths.

摘要： PROBLEM TO BE SOLVED: To re-edit data automatically in case of needing different machining from usual in a numerically controlled machining system. SOLUTION: In a numerically controlled machining system including a CAM system 10, a CNC 14 and a machine 16, CAM data 12 including an action data part 26 and an index part 28 is prepared in the CAM system 10. The action data part 26 includes machining action data, measuring action data and supplementary machining action data, and the index part 28 includes a machining index and a corrective machining index. The machining index includes following work determining information by action results. After machining a workpiece 18 according to machining action data, the workpiece 18 is measured according to measuring action data. In case of machining insifficiency, the CNC 14 is made to re-edit the machining index on the basis of the following work determining information by action results so as to execute necessary supplementary machining automatically at the appropriate time.

摘要： PROBLEM TO BE SOLVED: To provide a point string generation method which suppress the connection of tool pass points in a direction orthogonal to parallel tool routes. SOLUTION: A tool point string generation means 58 (tool point string generation process) executes a processing for generating a tool point string based on a point string interval Lij0 changed by a point string interval shift means 54 (point string interval shift process) from a start point decided by a start point deciding means 56 (start point deciding process). Thus, a processing for generating the tool point string based on the point string intervals changed to be mutually shifted in adjacent tool routes CP from the start points which are irregularly decided for respective unit curves UPi constituting the tool routes CP is executed. Consequently, the connection of the tool pass points in one direction crossing the parallel tool routes is suitably suppressed.

摘要： PURPOSE:To recognize the interference with a tool system even in the allowance to cast, the allowance to cut on the way of working, or the like by expressing the tool system with a solid model and extending the solid model in each part of the tool system. CONSTITUTION:The solid model with which the tool system is expressed approximately equivalently to its actual body form by a tool system expressing means M1 is extended and expressed in each part of the tool system by a tool system extending and expressing means M2, and the occurrence of interference between the tool system and a work WK is judged by an interference judging means M3 at the time of intersection between at least a part of the external form of the work WK and the extended solid model. Thus, the interference with a tool is correctly recongnized even in the allowance.

摘要： PROBLEM TO BE SOLVED: To shorten the required feed time when a tool is sent from the start point of a preceding actual working route to the end point of a succeeding actual working route as much as possible, in a method for controlling the feed speed at the time of sending a tool from the preceding actual working route to the succeeding actual working route not on the extension line through a free working route by a working machine so as to work a work with the tool. SOLUTION: Y direction acceleration and deceleration for increasing the Y direction components in a direction perpendicular to both of a preceding cutting operation block A-B and a succeeding cutting operation block D-E of the feed speed between the start point B and end point D of a picking operation block B-C-D and then reducing it are performed. Also, parallelly to that, second direction acceleration and deceleration for reducing and then increasing the X direction components in the direction parallel to the preceding and succeeding cutting operation blocks of the feed speed are performed with a point A' set in the middle of the preceding cutting operation block as a deceleration start point and the point E' set in the middle of the succeeding cutting operation block as an acceleration end point.

摘要： PURPOSE:To eliminate an unmachined part in the boundary section between adjacent attaching seats by machining the adjacent attaching seats so as to extend an upper stage side seat surface thereof toward a lower stage side seat surface thereof, and by continuously machining parts of the side walls of the adjacent attaching seats having heights equal to each other. CONSTITUTION:An upper stage side seat 12a' of adjacent attaching seats 12, 13 is machined for cutting so as to be extended toward the lower stage side attaching seat 13. A part of the side wall 13b of the lower stage side attaching seat 13, having a height equal to the side wall 12b of the upper stage side seat 12 is also machine continuously to the side wall 12b. Thereafter, the lower stage side seat surface 13a is machined so as to have predetermined dimensions, and the remaining part of the side wall 13b is also machined. In this method, no unmachined part is left in the adjacent parts of both attaching seats 12, 13, and further, no sector-shape unmachined part is left in a side wall corner part of each adjacent part during machining for cutting.

摘要： PURPOSE:To make no gap between cutting edges adjoining to each other by forming a boundary face between fitting seats adjoining to stair-like as slanting back toward lower side of an upstair side cutting edge from a side of the upstair side cutting edge to be abutted on a downstair side cutting edge. CONSTITUTION:Working data of a press mold 1 to a designing data, makes the boundary face 4 between the fitting seats of the upstair side 2 and the downstair side 3, so as to slant back toward lower side of the upstair side cutting edge 5 from the side face 5a of the upstair side cutting edge 5 to be abutted on the downstair side cutting edge 6. It is also executed under the same idea to make the working data on the boundary face 8 between the fitting seat 3 and the adjoining fitting seat 7. The mold for the press 1 is executed by N/C working, based on these working data to form each fitting seat 2, 3, 7 of the cutting edges 5, 6, 9. In this way, the fitting seat is formed, so as to make no gap between the cutting edges adjoining to each other.
