Cutting machine CNC controller Control System

Based on industrial PC in WindowsXP Embedded environment Software of the control system combines CNC operating functions with the peration functions of cutting process that were specially developed for PTV Company CNC control Different types of coordinate system transformation (shift, rotation, …) Parabolic ramps to ensure smooth motion Pre-calculation of trajectory with speed prediction in accordance with the machine’s dynamic facilities. 5-axial corrections for the use of A and B rotation axis in Progres Jet and 5AX functions Cutting process control Presetting cutting conditions (jet nozzle, pump pressure, abrasives …) Integral material database Material type and thickness option on the operating system, when the system itself determines speed, or, in CAD/CAM software. MFC function operates cutting speed in a way that optimises divergence between upper and lower side of the cut at the required quality. DRC function eliminates errors caused by variable width of the cut slit when jet enters material. Progres Jet function uses tilting of the jet for elimination of errors caused by narrowing or lagging jet. These errors are otherwise characterised by: cut edge not vertical (due to jet narrowing) and damage to product by jet reflecting, especially in inner corners (due to jet lag) Guidance of the operating staff by user friendly functions for manipulation with the machine and preparations prior to cutting
