CNC Machining Blog - Tips and Tricks for Machinists

Just like any other form of technology within our industry, 5-axis manufacturing has its very own vocabulary and list of technical buzz words. Although many of the features described below can be viewed as common, some are only found on the more advanced machine controls. For anyone looking into 5-axis machining, understanding these buzz words can be a huge benefit - and just might keep them from making an uneducated decision that they might live to regret later on.

A common misconception about the Hurco control is that it is a conversational control. This couldn’t be farther from the truth. Although Hurco invented conversational programming, and arguably has the most powerful conversationally capable platform on the market, I would not refer to the WinMax® control as a “conversational” one. I would instead call it “multi-lingual."

CAM systems have a diverse selection of toolpath strategies to choose from, and each has an appropriate place in 5-axis machining. But just like everything else in multi-axis programming, the programmer's experience and the actual machine configuration will play a big part in the selection of the suitable toolpath for a particular application.

If you asked 10 different 5-axis programmers to program the same single part, you would most likely get 10 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. 

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. 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 high-speed machining. 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’s patented Automatic Safe Repositioning (ASR) feature 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 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.
