Methods aim to reduce and/or eliminate the need for shims in manufacturing assemblies, such as in manufacturing of aircraft wings. Exemplary methods include predicting a set of predicted manufacturing dimensions within a range of predetermined allowances for a first part, manufacturing the first part, scanning the first part to determine a set of actual manufacturing dimensions for the first part, and at least beginning manufacturing a second part before the scanning the first part is completed. The second part may be manufactured based on the set of predicted manufacturing dimensions for the first part. Once the scan of the first part is completed, the set of predicted manufacturing dimensions may be compared to a set of actual manufacturing dimensions to check for any non-compliant deviances between the predicted and actual manufacturing dimensions. Repairs and local re-scans may be performed in the areas of the non-compliant deviances, which may streamline manufacturing.

To provide a numerical controller that is capable of analyzing a machining program so as to determine whether machining is machining placing emphasis on accuracy and machining placing emphasis on speed and vary an allowable speed difference. The numerical controller includes a determination unit and a corner deceleration control unit. The determination unit analyzes a machining program so as to determine which machining is to be performed between machining placing emphasis on accuracy and machining placing emphasis on speed. The corner deceleration control unit executes corner deceleration control based on a speed difference between cutting feed speeds on blocks leading and following a corner and an allowable speed difference which is predetermined. At this time, the corner deceleration control unit varies the allowable speed difference in accordance with a determination result of the determination unit.

Processes and systems for preparing sections of pipeline pipe for machine processing to form pin and box ends for assembly into pipelines using mechanical press-fit pipe joints. The prepared pipe sections are prepared to be fully measured and documented during both manufacturing and assembly. Installed pipelines include pipeline data monitoring systems coupled to a pipeline data management center for receiving, archiving, and analysis of the data records to aid in administration, operation and management, and troubleshooting of pipelines.

A controller for controlling a machine tool calculates a variation of a cutting load based on a changed rotational speed or feed rate of a tool in a machining program for machining a workpiece when the rotational speed or the feed rate is changed, and executes the machining program if the changed rotational speed and/or feed rate of the tool and/or the cutting load are within the ranges of predetermined upper and lower limit values.
