Simple Interface We have ensured that the cycle uses the information in the part and Code Generator where possible and kept the interface to only 3 modifiers that the user can adjust for the waveform pattern. The moves at depth can be at high Feed and allows the user to specify a small retract to stop the tool rubbing on the floor of the part. Stay at Depth When the tool stays at depth the path will automatically move around the stock when required. In localised areas the tool will stay at depth, but on long moves the tool retracts and rapids to position. When moving to the next cut the cycle will automatically choose the fastest method to get to that point. Linking the Tool Path The links within the cycle are aware of the rapid and High Feed rate settings for the machine tool. This also has the benefit of reducing shaking and vibration on the machine and component. Smooth Tool Path By ensuring the cycle produces a smooth tangent tool path, the velocity of the machine can be maintained and the desired feed rates achieved. As the material falls away the tool path step over is increased to maintain the desired engagement. When cutting a convex area the opposite affect occurs. The cycle adjusts the step over between the passes to compensate and maintain the desired engagement. When cutting into a concave area tool engagement is increased. Any remaining corners are then removed.Īutomatic Adjustment for Tool Engagement To maintain the tool engagement and the chip load the tool path is automatically adjusted to compensate. This can lead to the generation of sharp corners and discontinuous tool paths.įor pocket regions the tool will helical in to depth at the centre and open the pocket up so that it can create a continuous spiral cut until the edge of the pocket is reached. Traditionally, cycles generally offset the component until they meet the stock. This reduces the amount of intermittent cuts, particularly on external regions, which means the tool is engaged with the material for longer without lifting clear. The Waveform Pattern To maintain a constant chip load the cycle uses the philosophy that we machine from “Stock to part”. This will improve the tool life and greatly reduce the risk of tool breakage. In reality the machine tool operator may have to reduce the cycle feed rate to compensate and thus, increase the manufacturing time.Īs Waveform maintains a constant engagement the feed rate can remain at the optimal value throughout the cycle. Features at a glance:Ĭonstant Engagement With Material Although the Concentric pattern looks much simpler at the first glance the problem is that the tool “digs” into each corner causing the tool to overload, leading to reduced tool life or tool breakage.
The tool path moves in a smooth path to avoid sharp changes in direction which maintains the machine tool’s velocity. Waveform roughing strategy is a high speed machining technique that maintains a constant tool cutting load by ensuring the tool engagement into the material is consistent.
