There are two types of turret mounted live tooling on a CNC turning center. Axial and radial or 90 degree heads. First you need to find out the maximum RPM on the live tooling head. That should be etched on the head itself or by looking up the model number on the manufacturer's website. If it shows ...
High feed mills by design have a very low axial depth of cut. To recover the metal removal rate lost by such a small depth of cut, they are most often are suggested to be run at full width of cut and using very high feed rates. They exploit axial chip-thinning by increasing the effective radius of t...
Tap-testing thread mills does a great job of determining the best speed. Because of their low or no helix geometry thread mills are highly prone to chatter if you pick the wrong speed. The axial depth of cut and the radial depth are determined by the application and the thread mill program.The depth...
Use a lot of wax to hold the accelerometer, straight and perpendicular to the hammer tip. Use the major diameter of the dovetail as the cutter's diameter. Because we do not have a force model for this type of cutter, we can only accurately predict stable speeds. Generate a Dashboard and reduce the w...
With barrel, conical or tapered endmills, we can accurately predict stable speeds. Try to measure to up 1X the tool's major diameter from the tool tip to get off the angle as much as you can. Keep the accelerometer as flat and parallel as you can , perpendicular to the hammer hammer tip.We do not ha...
Setup the tap test like the image shown below. Tap in the X and Y axes. Set the Dashboard maximum DEPTH of CUT (DOC) to the key slot width. The Width of Cut (WOC) is the depth of the key slot.
1. Chose the indexable endmill setting which is 5000 Hz bandwidth and no weight/mass on the hammer.2. Under Setup, click on the Measurement tab and change the Response Direction on both the X and Y Directions to minus ("-") . BE SURE TO REVERSE THIS WHEN YOU ARE DONE WITH THIS CUTTER.3. Put the acce...
When you click on the Indexable FaceMill button on the SpeedCast menu, the software will automatically set the appropriate bandwidth and hammer settings. If you enter the tool's lead angle, the cutting stiffness of the workpiece material will be adjusted automatically. You will need to add the mass ...
We have had some success in tapping form drills, reamers and port cutters.Tap the tool like you would an endmill.Add the cutting depth per side and use that value as the Width of Cut (Ae) in Current Conditions.Use the hole depth as Depth of Cut (Ap) in Current Conditions.Make sure you have the right...
Since one insert cuts up and another cuts down, we may have to change the number effective teeth. Set the depth of cut to the full width of the slot and the width of cut to the diameter of the cutter.
This article is for the following endmills only: Kennametal KOR5 for Aluminum SGS Ski-Carb RobbJack FM Mirror Edge These tool have extremely high process damping characteristics, so use the "Special KOR5 SkiCarb FM" material database and then select the ISO N code for the material.ChipbreakersIf the...
Kennametal has revived the old Hertel Fix-Perfect tangential shoulder milling cutters and inserts. These inserts are freer cutting than other shoulder mills and therefore we need to lower the cutting stiffness value (K) in the Material Details page by roughly 50%. Be sure to NOT save the change in y...
Seco has introduced the Square-Six cutter which is a high feed mill with a 90 degree square corner. https://www.secotools.com/article/m_6920 While MillMax compensates for the lead angle of 45 degree and high feed milling cutters, the Square-Six is a sepcial case. Refer back to our original Special H...
