Hello everyone, I am UG programming teacher An. Today I will share with you the "CNC Programming UG/NX Multi-Axis Processing Cases". I hope it will be helpful for you to learn UG programming on ! Let’s officially enter today’s learning content.
main content is as follows: ( is also the UG/NX7.5 version as an example )
UG software As today's advanced CAD/CAM software, both modeling and programming have strong
functions, and is widely used in the design and manufacturing process of aircraft engines. It can complete the preparation of various types of CNC programs such as plane milling
, fixed shaft, multi-axis milling, and turning processing. At present, the
programming method of this software has been applied in many complex parts development processes. It must play an active role in completing the development task of parts

Projection method existing in the physical world
Three types of light sources are commonly seen in the physical world, namely point light sources (such as fluorescent light bulbs), line light sources (fluorescence light
tube) and parallel light sources (such as sunlight sources when the sun shines on the earth).
Correspondingly In NX software, we will also explain the projection
method and a relatively special type of surround light source class according to the above concepts.
point light source class: Away from point, Towards pointtml2
line light source class: Away from line, Towards line
parallel light source class: Specify Vector, Tool axis (it is difficult to define which category belongs to, temporarily consider classifying it according to the specified axis
in parallel light source class)
surround light source class: Normal to drive, Towards drive (More special)

Optimization and Driver (Optimized to DriveSurface)
§ Optimized
In the drive shaft control method, automatically matches the tool axis guidance angle according to the curvature of the drive geometry. In the convex area of the outer
, NX maintains a small guide angle to cut off more materials. In the concave area, NX automatically increases the forward angle to prevent the tool heel
overcut driving geometry. At the same time, the forward angle is kept as small as possible to prevent the tool front end from overcutting and driving geometry
§ only applies to surface driving methods
