When cutting with low speed, the jet will erode more material from the bottom of the part than cutting with higher speeds. Since we are making speed compensations for corners etc. the measurement on the top/bottom of the part is different and the angle will not be straight.
By activating the taper control, the jet will compensate for these errors and make straighter cuts.
DESIGN 3D PARTS FROM 2D
You can make standard 2D parts in IGEMS and add cutting angles afterwards. It’s perfect for fast programming with simple designs. You can also create 3D parts from a top and a bottom geometry. When using this method, you can create more complex 3D parts using IGEMS.
3D-5X can use STEP and IGES files containing surfaces and solids. It means that you can cut directly on models from your 3D system. (Inventor, SolidWorks, SolidEdge etc.) Just open the file in IGEMS and add a toolpath. 3D-5X is very easy to use compared to other 3D softwares, even on complex geometry.
Full 5 axis machining
3D-5X will supply you with full 5 axis information, meaning X, Y and Z linear positions and A, B and C information for the 5 axis kinematics.
The speed optimisation is very important for 5 axis cutting. It’s calculated from the actual thickness at every point, the geometry profile and the tilting direction. Piercing times are also calculated in a similar way. All the speeds are optimized from your pump pressure, orifice, mixing tube diameter and the amount of abrasive.
It’s also possible to control what portions of the model to cut. In this example, (A) is cut from the top of the contour to the cutting table. (B) is cut with just the length of the edge.
The 3D-5X parts can be nested just as any normal 2D parts. It’s calculated with the different cutting angles so the jet won’t damage other nested parts.
IGEMS can make full 3D simulation of the actual part and the 5 axis kinematic cutting head before you start cutting. It means that you can see what will happen before you cut your parts in the machine.
