CAD-CAM Buyer’s Guide: Mill 4 Axis Standard vs Mill 4 Axis Professional


Users who are doing 3 Axis work on a 4 Axis machine, utilizing the rotary for positioning, will find products like BobCAD-CAM’s Mill Standard to be most effective. Machinists that are performing full simultaneous 4 Axis work will find their Mill Professional module to be more to their liking. With that being said, which module is right for your shop? Let’s look at these 2 and highlight the benefits both modules provide to the user.

Mill 4 Axis Standard
Mill 4 Axis Standard is very popular with manufacturers! Here are 4 key features any shop with a rotary table will benefit from.
4 axis indexing in cam software
1- Indexing
Sometimes called “3+1 programming”, Indexing positions your part at various, user-defined angles. Simply select a surface or UCS to index the part in 2D or 3D.
2- Wrapping Groups
Wrapping Groups machine around the outside diameters of your part and can help users create pockets, engravings or even profile a J slot using Wrapping Groups.
3- Rotary
The Rotary Toolpath will support directly machining your solid model while utilizing your 4th Axis. This can be similar to turning a part on a Lathe machine, as the 4th Axis is spinning, the part and tool move up and down in ‘Z’, following the surface of your model. Rotary Toolpaths boast settings for direction control, cut increment and roughing. Rotary Toolpath is easy to program and very powerful.
4 axis cad-cam software cross drilling
4- Cross Drilling
Utilizing your 4th Axis to drill holes is a powerful way to make sure holes stay concentric from one side of your part to the other side. Reduced setups is a big part of why shops turn to 4th Axis machining, to begin with. The Cross Drilling feature has the ability to automatically detect and program the cross holes of your parts. Simply select your solid and go!
Note: Mill 4 Axis Standard wrapping groups use axis substitution rotary moves.
Mill 4 Axis Professional
This module provides users “true 4 Axis” programming. Mill 4 Axis Pro provides users 7 surface based Toolpaths with full tilt control of the tool angle to the surfaces that are being cut. You can also cut off centerline as you follow the surface or solid being programmed. That “Y” move makes a big difference while programming perpendicular pocket walls & other shapes. Having control of the point distribution is key for machines to run as smoothly as possible.
Note: 4 Axis Professional includes Full Machine Simulation. This means users can visualize their setup, part, Toolpath and machine components in a virtual environment. Machine Simulation is required to develop an NC file free of errors.
