If you asked ten different 5-axis programmers to program the same single part, you would most likely get ten different machining strategies. Depending on experience, machine configuration, CAM software, tooling, workholding, and a myriad of other criteria everyone sees the path they need to travel just a little bit differently. But they all lead to the same place…a successfully completed part. This article will be part one in a multi-part series about 5-axis programming.

I was recently asked to explain the motion control system, used in CNC machine tools, to someone in my family. Realizing that this individual didn’t have a background in manufacturing at all – and certainly had no experience with anything this complicated and technical – I had to relate my explanation to something common and simple, allowing them to easily visualize the analogy….like driving a car.
For some reason 5-axis machining just scares people. While talking with people at trade shows, or when discussing the potential of a customer’s parts being a good fit for 5-sided machining, you can just see an uneasy feeling begin to overwhelm them, and you can see the fear begin to well up in their eyes. The mere thought of all of those axes moving at one time, sends them wanting to run for the hills. But if we take the time to look at it logically, and break it down to what is really happening, it isn’t scary at all!
For many years Hurco has offered an easy conversational solution for programming simple 3D geometries, at the control, without the need for expensive CAD/CAM software…but with today’s WinMax control it’s even easier and more powerful than ever before!
WHAT IS HIGH SPEED MACHINING?
High speed machining is usually associated with any spindle speed above 15k rpm, but it is much more than just a faster spindle. The whole machine must be considered when selecting a good candidate machine for HSM. Thermal compensation, overall machine rigidity and construction, positional feedback, the motion control system, tool retention, and many other characteristics must be looked at, in detail, before determining that a particular machine is suitable for the task.
Hurco is well known for our powerful and easy to use conversational software; and for 2D and simple 3D geometries, the WinMax conversational control simply can’t be beat. But what about those jobs that share both simple 2D features and complicated 3D shapes - that can only be programmed using CAD/CAM software? Well, Hurco has an answer for that as well.
Hurco’s patented ASR feature (Automatic Safe Repositioning) is a very powerful tool for 5-axis NC or CAM programmers. One of the biggest problems when posting 5-axis NC code is configuring the post to always output safe, reliable data to reposition the tool-tip without causing the machine to travel out of limits on rapid moves, and to display those annoying error codes that we all love to hate.
Hello, and welcome to the Hurco blog. I will be updating and posting something new each week on a variety of different subject matter: high-speed and 5-axis machining, workholding, the latest control technologies, and Hurco tips-and-tricks…just to name a few.
