ZW3D 2019 and its SP version are available with tons of new features and enhancements. In the previous article, we’ve already unveiled the hidden enhancements in ZW3D 2019 CAD module. So today, I am going to show you some of the highlights which are not easily discovered in CAM.
1. Smooth corner transition for 2-axis operation
In ZW3D 2019, arc control was added to optimize the tool path when dealing with contour corners. Compared with ZW3D 2018, the tool path created in ZW3D 2019 is rounded at contour corners as the image shown below.

These round trajectories can lengthen tool life, make the machining process smoother, and improve machining quality.
So, how to set a desired radius? In ZW3D 2019, you can set a suitable value for Side Finish Radius to generate the tool path with round corners.

2. Optimized lead-in tool path for Helical Cut
In the 2018 version, the lead-in tool path is under the horizontal plane, which may cause the failure of infeed. Now the lead-in tool path is above the horizontal plane, bringing forth ideal helical cutting results.

Besides, the control of machining depth is more flexible with Max Cut Depth and Output Type, which can be set according to the machining requirements as shown below.

Moreover, ZW3D 2019 supports Helical Cut not only for 3-axis but also for 5-axis machining.

3. Smarter feature detection of Flat Region
Previously, when we define the flat region of a part for Flat Finish operation, a lot of facets will be mistakenly detected due to some division lines. Now in ZW3D 2019, the boundaries can be intelligently chosen to deliver neat trajectories as shown in figure 6, so that the flat region can be recognized and selected correctly.

4. More reliable big-step cutting without residues
In the previous version, when the stepover of 3-axis roughing exceeds 80% of tool diameter, there will be residues after Rough Offset operation. Now, as the right picture of figure 7 shows, the part after being roughed is perfect without residues in ZW3D 2019 thanks to the upgraded big-step cutting, delivering more reliable roughing results.

5. Improved cut order for hole feature
In actual machining, it would be convenient if we can set the drilling sequence flexibly. In 2019 SP version, the hole processing sequence can be customized. The Cut Order can be decided by Pick Order, which means that the holes will be processed according to the Pick Order.

6. Optimized link types

Traverse Straight has been added to the last cut of processing, which can reduce unnecessary links to improve the efficiency of cutting ramp.

That’s all for today’s sharing. There are still a lot of “hidden surprises” in ZW3D 2019 and its SP version, which will help you deal with more complex products from designing to manufacturing. Why not find them by yourself? Download ZW3D 2019 SP >>
