CNC Machining Blog
In February of 2013 I posted an article titled: “5-Axis…it just ain’t that scary”, and to date it has been one of the most popularly read articles in my blog series. So, I thought I would expand on that article a little bit, and dive a little deeper into what can be done with 5-axis technology…and show how even the advanced features of 5-axis really aren't anything more than multi-axis common sense, when you break it down.Read More
Hurco recently partnered with Modern Machine Shop magazine for an educational online 5-axis webinar, called: “Take Five for 5-Axis”. It was very well received by everyone who attended, and the feedback afterward was outstanding. In this webinar, I try to present this information in a very simple way, and attempt to explain things in a manner that even those who have no history of 5-axis machining can understand it. After all, that was the intention…to educate and teach!Read More
As machinists we apply our skill, knowledge and experience to produce the best looking and most accurate parts that we can. We take a great deal of pride in the products that we produce, and we want others to see that pride in the finished product. But what do we do when we aren’t getting the results that we want? When dimensionally the parts meet blueprint specifications, but the surface finish and overall appearance is less than desirable? When this happens we need to go back the basics and ensure that we are using the best machining practices that we know to be correct.

There are several things to keep in mind when you are in the market for a new 5-axis machining center. To be successful, you must make sure that the machine will fit all of your needs, not just your current one. Often times the purchase of a 5-axis machine is driven by a particular job or part, and sometimes shops fail to consider the other work they could run on the machine. Remember, size does matter.
Earlier this year, I reviewed the results from the Benchmarking Report by Modern Machine Shop called TOP SHOPS and promised to give you an update when the 2013 results were published. This blog post only touches on a fraction of the information contained in this incredibly extensive report—the Executive Summary alone is 22 pages—so I encourage you to explore Modern Machine Shop’s TOP SHOPS ZONE
Regardless of a particular OEM machine builder, there are several common machine configurations for 5-axis that are available - and each one has its own set of strengths that make it stand out among the choices. The most common types are: Table-Table, Head-Table, and Head-Head configurations.
When programming in 5-axis, we have two distinct options that we can use to command rotary moves and positions. We can output the data using either rotary angles, or tool vectors. Although each one has its pros and cons, I would prefer to configure a postprocessor to output these rotary commands as IJK tool vectors, instead of the more common ABC axis rotary angles, if given a choice.
As machinists we are all aware of the standard tools of our trade; however, there are other non-standard tools available - that not everyone is aware of - that could be very helpful in our day-to-day life in the shop. Just like any other industry, if there is a time consuming and mundane procedure that must be completed, you can bet that somewhere there is someone who has already invented a tool or device that would make that task easier…if we only knew where to go to find those tools.
