Benefi ts A Breakthrough Waterjet Cutting Process

Cut parts 25-400 % faster than conventional at stock waterjet cutting machines Dynamic Waterjet with Active Tolerance Control, produces more accurate parts at signifi cantly higher cutting speeds than parts cut with a conven-tional waterjet. This patent-pending system utilizes a newly developed advanced motion system that incorporates unique mathematical cutting models, developed by a team of researchers led by Mr. Glenn Erichsen, a senior scientist at FLOW. These models control a small, articulated wrist that is attached to the cutting head. The wrist allows the cutting head to tilt in any direction, compensating for the stream lag and taper experi-enced with conventional waterjet cutting machines. Stream lag and taper are a natural, but undesirable, result of cutting with a beam-type cutter such as a waterjet. The faster parts are cut, the greater the stream lag. Stream lag causes part geometry errors. In addition, as cut speed is in-creased through a given material, the waterjet beam produces ever-increas-ing taper. Conventional waterjets must slow down in order to reduce or eliminate fi nished-part tolerance errors caused by stream lag and taper. Now, with Dynamic Waterjet, these limitations are overcome. Օ Improve cut part tolerances and geometry at signi cantly higher speeds Virtually eliminate taper Օ Reduce cost per part by up to 75 % True part stacking ability withconsistent tolerance layer to layer Օ No secondary nishing required Cut a variety of materials, suchas metal, stone, glass, and
composites Օ Easy to program; no specializedtraining or knowledge required >

FlowMaster

Software

Ε Cut parts using virtually any CAD le, or scan a drawing directly into FlowMaster The Erichsen Models are seamlessly integrated into FlowMaster, FLOWs intelligent, PC-based waterjet control system so that operating the Dynamic Waterjet is extremely simple Җ no specialized skill or knowledge is necessary. All mathematical calculations take place behind the scenes, triggering the appropriate motion commands to all fi ve axes at lightning speed. The user simply enters the basic cutting parameters, such as material type and thickness, cut speed, and desired edge quality, and FlowMaster does the rest. FlowMaster dynamically controls the position of the cutting head. It knows the amount of tilt and rotation required at nu-merous incremental points along a cutting path. For example, at high speeds outside corners require increased tilt to prevent coning. FlowMaster also knows the optimal cutting speed to keep parts within tolerance and taper free. The faster the cutting speed, the more tilt that is required. In most cases the ability to tilt the cutting head allows for a faster cutting speed. Because of this, Dynamic Waterjet produces superior part features at higher speeds than those resulting from conventional waterjet cutting. >
