ZW3D Quick Mill Enhances CNC Programming Efficiency
Does it get annoying to repeatedly define features of imported 3D models? Does rest milling cost you unnecessary extra programming time? Do containment definitions drive you crazy?



If so, then consider ZW3D, which gives CAM engineers like yourself rapid and efficient programming through the application of autofeature recognition, batch calculations, rapid rest roughingand rest finishing,and flexible containment.
mmediately, the definition of the machining feature is finished. Next, I need to define the tool and its parameters, following which I can calculate the results.



2. Batch Calculation

After defining the machining feature and other necessary aspects, such as the tool, process parameters, and so on, I can go on to calculate it. ZW3D provides a batch calculation function, so that I can go do other jobs while waiting for the calculations to finish. This feature helps you make full use of your time. Figure 2 shows the processing.



Let me take you through a real case study to show you how ZW3D excels in each of these areas.



1. Automatic Feature Recognition



ZW3D’s Quick Mill module allows you to create tool paths directly from the whole part and stock. There is no need to define it manually, and so when you program Quick Mill, you do not need to select the machining area.



Here is the actual part I will use in this article; see figure 1. I’ll load it into ZW3D, and then select a roughing operation from the Quick Mill module. I’ve picked Rough Smooth Flow, and then directly selected the part and the stock as the machining feature.
3. Rapid Rest Roughingand Rest Finishing



Thanks to the reference operation and reference tool, I don’t need to find the areas that cannot be cut by the big tool in the previous operation; through just one quick operation, the system detects the areas that need further cutting.



I’ll select another roughing operation; this time, it’ll be Offset 2D to get the rest roughing tool path.



First, I select the Offset 2D Operation from the Quick Mill module, and then under this operation I choose the Ref Op item from the tree. I select the previous rough as the reference operation, as shown by figure 6.
4. Convenient and Flexible Containment



Quick Mill cuts both steep and flat areas quickly, using angle limitations and user-defined limits to cutting regions. Limits and tool paths can be defined with a variety of geometry, such as curves, surfaces, and even curves with gaps.



Let me return to my example shape to get the finishing tool path on both flat area and steep areas. First, I’ll select the Z-level operation from the Quick Mill module, and then I’ll choose the whole part as the machining feature; for the tool, I’ve picked the 16 mm Ball End Mill.



Next, I go to the parameter section of the operation setup, and (a) pick Limiting Parameters, (b) choose Angular tap, (c) set the Min Angle to 10, and (d) the Max Angle to 90
From the result I see that there are two problems that need to be solved. Firstly, some parts of the outside tool path are unnecessary. Secondly, there is too much lead in and lead out between tool paths. Fortunately, I found that in ZW3D it is easy to eliminate these problems.



First, I’ll go to the Limiting Parameter again, pick the XY tap, and then set the % Offset into 10. I’ll continue to theLead and Link Parameters to set the % Short Link Limit to 2000, and then recalculate the tool path. From this, I get a new path that looks like the one in figure 10.
