TrueMill Calculator (see below article and tech tip)

In addition to these new features, enhancements have also been implemented into the patented TrueMill® toolpath including an updated slicer for better quality toolpaths, faster toolpath calculation time, intelligent pocket ordering that dramatically reduces overall rapid moves, the ability to turn off the "open pocket" cutting for 3-axis cuts, "depth first" cutting to allow for more efficient tool motion, and pilot hole support for TrueMill operations. To learn more about SURFCAM V5, contact your local dealer or download the SURFCAM V5 What's New document.

The TrueMill Calculator

Have you ever wondered if it is possible to achieve greater machining productivity out of your existing CNC machines in your shop? Does it seem that every time you need to cut a part you are pressured for time and need more speed to get the job done? Do you wish you could achieve more life out of your machines and tooling?

You can reduce your cycle times, increase machine and cutting tool life and achieve higher material removal rates with a patented toolpath called "TrueMill."

TrueMill is a quantum leap in CAM toolpath technology. A TrueMill toolpath controls the tool’s engagement in the material being cut to maximize the material removal rate (MMR). TrueMill allows a cut that is both faster and deeper than any other 2 and 3 axis roughing toolpath on the market today. TrueMill's effectiveness and speed is especially evident in difficult or exotic materials such as titanium, inconel and hard steels.

TrueMill Calculator

SURFCAM V5 now comes equipped with the TrueMill Calculator. This easy-to-use calculator was created for end-users to obtain the most optimum parameters and the highest material removal rates with TrueMill. The calculator comes loaded with recommended parameters for a variety of materials. These parameters, which can be switched to either metric or inch according to the user's preference, can be altered and saved for reuse. The suggested parameters in the calculator are intended for TrueMill Certified Tools only.

The TrueMill Calculator can be loaded from either the Start Menu or SURFCAM V5 with the TrueMill Option. If you do not have SURFCAM V5 and would like to try it and/or the TrueMill Calculator, please click here to register and download the FREE SURFCAM V5 Student/Demo Learning Version.

Surfware Tech Tip

Getting the most out of TrueMill with the TrueMill Calculator

Would you like to learn how to use the new TrueMill Calculator to improve productivity with TrueMill?

The TrueMill Calculator was designed with ease-of-use in mind. To use the TrueMill Calculator, begin by choosing the material from the drop down menu. This is done because each material has different physical properties that contribute to the recommended cutting parameters. Next, input the diameter and number of flutes for the tool you want to use.

Click inside the SFM box. SFM stands for Surface Foot per Minute and is one of the key parameters for properly using TrueMill with any kind of material. By clicking inside the SFM box, a small window will appear with recommended starting parameters. If this is your first time using the TrueMill Calculator, it is recommended that you enter the middle value. This will cause the RPM to be calculated automatically.


Next, click inside the Tool Engagement Angle (TEA) box to bring up a set of recommended TEA values. Tool Engagement represents the portion of the circumference of the cutter contacting the material, measured in degrees. Tool Engagement is also the foundation behind the patented Engagement Milling technology (US Patent 7451013) that TrueMill is built on. As with the SFM, enter the mid value. This will cause the stepover to auto-calculate.


Choose the box for chip thickness and input the middle recommended value. The chip thickness is the maximum thickness of the chip that is generated by a cut. This value should not be mistaken with the tool manufacturer's chip load. The thickness of the chip is important as it ensures that the tool is not being damaged by making shallow or deep cuts. After inputting the chip thickness, the recommended feed rate will be auto-calculated.


Finally, input the depth you want to cut. With TrueMill, it is possible for a depth of cut to be about two times the tool diameter. For example, with TrueMill, it is common to cut one inch deep in materials such as Titanium with a half-inch end mill.


After the depth has been entered, the Material Removal Rate (MRR) and the estimated horsepower will be calculated. It is important to check that the estimated horsepower does not exceed the potential of your machine. Surfware recommends making a test cut with these parameters before machining your part and adjusting the parameters up or down as you see fit. Remember to use these parameters from the TrueMill calculator when programming your part instead of the default parameters given by TrueMill dialog boxes in SURFCAM.

By practicing proper usage of the TrueMill calculator, you can ensure that your investment in TrueMill is being used to its full potential and boost your productivity.
