Turbine Engine manufacturers are developing solutions for their Laser drilling and cutting Systems which will dramatically speed-up the process of going from part-based geometry data to final machine-based part programs, hence increasing productivity substantially by more efficient utilisation of expensive capital investment in multi-axis Laser machine Tool Systems. The increasing complexity of Turbine part design, including the use of computer-based 3D solid modelling has in many cases made the Manufacturing Engineer's (ME) job more difficult rather than easier. ME's are tasked with defining on-machine operations for parts whose machining, casting or fabrication details may be defined in various ways from legacy 2D prints to 'state-of-the art' 3D solid models. The requirement to "map" and probe Workpieces, allowing for inherent variable geometry to correct for final machining positions, requires significant data-manipulation of part surface geometry and position tolerance limits, etc. This is achieved by the introduction of an on-machine Computer with a 'real time' interface to the final CNC providing a suite of highly-graphical, interactive editors which form a bridge between the geometric definition of the part to be machined and the creation of actual part-machining cycles.
