摘要:
A method and apparatus for machining a part for an assembly (100, 202, 400). First sensor data (226) is acquired for a surface (203, 506) of a first part (101, 204) from a first sensor system (222). Second sensor data (228) is acquired for a set of existing holes (232) in a second part (102, 206) from a second sensor system (224). A surface model (238) of the surface of the first part (101, 204) is generated using the first sensor data (226). First offset data (240) is computed based on a nominal model (242) of a third part (104, 208) that is nominally positioned relative to the surface model (238) within a three-dimensional virtual environment (245). Second offset data (241) is computed (708) for the set of existing holes (232) using the second sensor data (228). Overall offset data (246) is generated (710) using the first and second offset data (241), wherein the overall offset data (246) is used to drill a set of holes (214) in the third part (104, 208) for use in fastening the third part (104, 208) to the second part (102, 206).
摘要:
A system for preparing an NC sentence for two-step drilling according to which a hole formed by the first-step drill is further deepened by the second-step drill of a smaller diameter. Data related to a machining shape are input (S1), and data related to machining conditions are input (S2, S3) inclusive of a first clearance and a second clearance. An NC sentence is prepared (S4) for the first-step drilling and the second-step drilling from the bottom of the hole formed in the first-step drilling to the final point of machining. This helps reduce the time for the second-step drilling.
摘要:
An arbitrary hole shape pattern (HPT) and its machining procedures are specified interactively to register the result as hole kind data in a hole kind file (FLD). When the registered hole kind is designated from a keyboard (14) at the time of preparation of NC data for boring, an automatic programming portion (11) displays an interactive picture in accordance with the hole kind on CRT (13) so as to specify the hole shape dimension and tools used for each machining step and the NC data for machining the kind of the hole is prepared on the basis of these data.
摘要:
A method of setting a boring condition by which the working condition for defining of boring in an automatic programming can be set easily. In this method, when one of various registered bore form definitions displayed is selected by an operator, it is asked whether change of a registered working condition corresponding to the selected definition is necessary or not (S1) and if unnecessary, the registered working condition is set as a set working condition (S2). When the changing is selected, first and second coefficients are read out from a look-up table according to the combination of a work material represented by manually inputted data and the kind of boring relative to the selected bore form definition and the size of the tool. A rotational speed of the main shaft is calculated on the basis of the first coefficient and the manually set cutting speed, and a feed speed is calculated on the basis of the calculated rotational speed and the second coefficient to set both the calculated rotation and feed speeds as the working condition (S3). After the set working condition is changed as required, inputting a bore position (S7, S8), the defining of the boring is completed.

On découpe la voie en un certain nombre de tronçons et pour chacun de ces tronçons on procède, pour chaque file de rails, aux opérations suivantes :
a. on sélectionne parmi plusieurs profils de référence un profil de référence préféré; b. on détermine un certain nombre de types d'usure caractéristiques du rail à reprofiler parmi les types d'usure répertoriés. c. on sélectionne le type de machine devant être utilisé pour le reprofilage parmi différents types de machine à disposition, ainsi que sa vitesse de travail; d. on définit des configurations standard d'outils tant en position qu'en puissance; e. on sélectionne, en fonction du type de machine à reprofiler devant être utilisé, les configurations standard d'outils pouvant être réalisées avec cette machine; f. on mesure les longueurs et/ou les amplitudes des ondulations longitudinales sur le tronçon de voie envisagé; g. on mesure le profit transversal du champignon du rail sur le tronçon de voie envisagé; h. on compare le profil mesuré du rail avec le profil de référence préféré et détermine l'excès de métal à enlever; i. on compare le profil transversal mesuré du rail aux différents types d'usure possibles et détermine par cette comparaison la catégorie de reprofilage à utiliser qui est représentative du tronçon considéré. j. on détermine en fonction de la catégorie de reprofilage représentative la configuration standard d'outils particulière à utiliser parmi celles sélectionnées pour la machine à utiliser; k. on détermine en fonction de la configuration d'outils particulière à utiliser, de la catégorie de reprofilage à utiliser, de l'excès de métal à enlever et de l'amplitude des ondulations longitudinales, le nombre de passes total à effectuer.

摘要:
A method for conforming components may include a measuring operation and a modifying operation. The method may comprise measuring a first component using a conforming tool that includes a measuring member, and recording position data for the first component based on the measuring. A path for the conforming tool may be provided using the position data, and a second component may be modified with a modifying member by moving the same conforming tool based on the provided path. The measuring member may include a sleeve configured so as to surround the modifying member when measuring, and to be removed from the modifying member so as to allow the modifying operation.
