Abstract: A method of borehole pipe installation begins with unfinished stick pipes brought to the installation site and then machined or cut to form male and female ends. The pipe ends are then locked together to form a flush joint. The lock can be provided via a groove cut into one of the ends for receipt of a lock gasket, which secures and seals the joint when the pipes are pushed together, and prevents the pipes from being pulled apart. Alternatively, to the groove and lock gasket, the ends can be glued and screwed together, with the screws allowing the joined pipes to be pulled through the borehole before the glue is dry. The pipe joint has flush exterior and interior surfaces to minimize borehole clearance and maximize fluid flow through the pipe assembly.

Abstract: According to one example, a CNC machine tool system may perform error compensation for improving the accuracy of the geometry (or form) of a machined workpiece to, for example, better than 2 micrometers. To do so, a first machined workpiece may be created using the CNC machine tool system. The CNC machine tool system may create the machined workpiece by jig grinding. Following the creation of the first machined workpiece, metrology of the workpiece error may then be performed on the machined workpiece. The metrology of the workpiece error may be used to create a corrected toolpath trajectory for re-machining. This corrected toolpath trajectory may then be utilized by the CNC machine tool system to machine a second machined workpiece having a geometry (or form) with an accuracy of, for example, better than 2 micrometers.
