Dynamic Motion in Action – What Makes it Different
What makes dynamic toolpaths truly different is their ability to consider various alternatives about what to do next and then make an intelligent selection based on a high-powered analysis of what impact the various options will have on the final outcome.
There are a number of entrance schemes that will allow toolpaths incorporating Dynamic Motion Technology to efficiently enter the part so that it can best utilize the algorithm for machining. That’s its first choice.
Let’s assume it goes into the more open side of the pocket. It spirals its way out– always having constant contact– climb milling so you avoid the conventional back and forth–until it runs into a wall. Then it has the intelligence to figure out what the most efficient thing it can do next. It has awareness of the stock that allows it to direct how the tool moves.
Say it goes into the corner of the pocket. When it runs into a wall it will reposition itself outside of the material– because it knows where the material isn’t in addition to where it is and it re-enters.
The way it enters and exits the material is controlled and very efficient. It is not wasting moves cutting air. The only time it is cutting air is when it is repositioning. And even this is not wasted motion. It’s repositioning the tool so that respects the tool, it respects the stock, respects the product.
Where some tools will retract to a clearance plane or a retract plane, dynamic toolpaths only retract a small amount. It’s important to make this tiny retraction because scrubbing the floor generates heat. Heat generation is the carbide cutting tool’s worst enemy because it causes cracks, fissures and microfissures that cause the tool to dull prematurely. So dynamic toolpaths know how to do little pirouettes—microlifts of 0.005″ to 0.010″ to keep the tool from scrubbing the floor.
