Abstract:
1. A process for machining a blank from all directions with a machine tool, the machining from all directions being based on a three-dimensional template, wherein the three-dimensional template is for a blade that is to be replaced in a turbine, the blade has a length greater than 200 mm, and the machine tool includes a machine bench having an A-axis and a W-axis, the process comprising: automatically measuring three-dimensional spatial form and optionally surface finish of the three-dimensional template, and saving associated measurement data, the three-dimensional template being restrained in clamped position during a portion of the measuring at ends thereof in the A-axis, and the three-dimensional template being restrained at a central region thereof during another portion of the measuring for tip and root regions of the three-dimensional template; holding the blank with at least one first clamping adapter while preparing a first region into final, ready to use partial form with the machine tool using said measurement data for numerical control, wherein while preparing the first region, the blank is grasped in the A-axis of the machine bench, with the blank being grasped proximate at least one end thereof using the at least one first clamping adapter and being fixed at another end using a movable tailstock; and holding the blank with at least one second clamping adapter in the first region that was already prepared, and preparing a remaining region of the blank into final, ready to use overall form with the same machine tool using said measurement data for numerical control, wherein while preparing the remaining region, the blank is grasped on defined clamping surfaces in the W-axis by clamping jaws of the at least one second clamping adapter.
