CNC Machining Blog - Tips and Tricks for Machinists

Even the most carefully maintained machining centers eventually become obsolete. When it’s time to replace your older machine, look for one that gives you the maximum dollar value for your investment. 5-axis machining centers are versatile, efficient and flexible, and one can do the work of two or three 3-axis machines.

With that new machine comes an opportunity to upgrade your tooling, as newer machining centers can handle more advanced tooling options. Consider these tooling variables when purchasing a new 5-axis machine.

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 original equipment manufacturer machine tool builder, there are several common configurations for 5-axis CNC machines that are available. 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 prefer to configure a postprocessor to output these rotary commands as IJK tool vectors, instead of the more common ABC-axis rotary angles.

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 and could be very helpful in our day-to-day life in the job 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.

Here is a list of helpful products for machinists that addresses workholding, fixture building, part and tool setup, coolant nozzles and more:

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."
