CNC Machining Blog - Tips and Tricks for Machinists

Anyone who runs a 5-axis machine knows how important accurate centerline measurements can be for accurate machining. Often times, however, when troubleshooting process issues, or after a slight “bump” of the machine, there might be a need to verify or re-measure these centerline values. This usually requires a costly service call, and, even more painful, costly downtime of the machine while waiting. Although there is no substitute for the accuracy of the certified kit used by Hurco and distributor service personnel, this procedure will hopefully allow customers to keep their machines up and running (even if it is only while waiting for the service technician to arrive).

Earlier this week, a few of us here at Hurco were invited to a local function to meet the command staff of a newly commissioned Virginia Class Nuclear Submarine, for the U.S. Navy, named after our very own Hoosier state - the USS INDIANA…and, as it was written on the picture below, by the skipper of the Indiana, Commander Jesse Zimbauer, this submarine is “Hurco made”.

Hurco has many different partherships - some in education, tooling companies, CAM software compalnies, and both Indy Car and NHRA drag racing. Even though every single one of our relationships are important and special in their own way, one of the coolest relationships that we have is with John Force and the John Force Racing team.

I'm acting as guest blogger for Mike Cope today because he took a vacation day to honor veterans as he has done each Veterans' Day for the past 17 years with his best buddy and Navy veteran Dave. Mike has many interests, but he is passionate about patriotism and serving veterans and active duty military personnel. Therefore, he takes November 11th seriously...it is just one of the days during the year that he gives back to local veterans through honor and service.

Professionally, Mike is the go-to guy when it comes to understanding how the Hurco control makes machinists more productive and shops more profitable. He knows the control inside and out, and helps all of us make sure the end user understands the value of the multitude of software features WinMax provides. 

One of the features about a Hurco that many customers love is the 8-nozzle coolant ring that comes standard on all VMX models of vertical machining centers, and the amount and flow of the flood coolant that can be experienced is sometimes unbelievable to many new users. Now Hurco VM owners can experience this same overwhelming feeling of flood coolant!

A while back I received a comment on one of my previous blog posts – “5-Axis Programming: programming with tool vectors”-  asking about how to designate a 5-axis Transform Planes using IJK UVW vector tokens, instead of the traditional ABC rotary axis designations on their 5-axis CNC machine. Instead of just replying to that comment, I thought I would write this post as a response. Since this will be a continuation of the 5-axis CNC basics series, I suggest that you read and understand using IJK tool vectors as a pre-cursor to this article. 

The idea behind creating a 5-axis transform plane using vectors is exactly the same as programming tool movement with IJK tool vectors on any machine with a 5th axis; however, the difference lies in the fact that you will have two separate vectors…using IJK for one and UVW for the second one. The reason you need two separate “legs” for this function, is because you cannot designate a plane with only one axis. I will use the floor inside a room as my analogy…you could not create a floor in a room without having at least two walls. With only one, the floor would simply spin around that single axis, and could actually point in literally any direction. To accommodate the two legs of the transform plane, and because we want to determine the direction of the Z-axis ultimately, we will use the X-axis and Y-axis as our legs, or walls of the desired transform plane.

Today’s Hurco users are well aware of the term SFQ, or Select Surface Finish Quality, on the Hurco control, and probably have a pretty good idea about which settings work best for them – however, many of them probably don’t realize what is actually going on behind the scenes, and what those settings actually mean or how they affect the machine’s behavior.

Over the years, Hurco has partnered with many tooling companies. Recently I received a link from G.W. Shultz, that showed a video of one of thier tools cutting 422 Stainless Steel, on a Hurco VMX30HSi High Speed milling machine - at some pretty impressive speeds. The information listed in the video comment section says: "Pushing the G.W. Schultz Tool HGW40250-01 to 1000SFM in 422 Stainless Steel".
