Let’s talk about chatter in milling. The top left photo shows an experimental setup we used to measure signals during milling. The steel workpiece was mounted on a flexure. This simulates a flexible workpiece, such as a turbine blade. The flexure displacement and velocity were measured using a laser Doppler vibrometer (LDV). The top right panel shows a stability map. It separates the stable and unstable/chatter zones based on spindle speed (horizontal axis) and axial depth of cut (vertical axis). The bottom left panel shows a Poincaré map that plots the flexure displacement (horizontal axis) versus its velocity (vertical axis) in the x (feed) direction. The dots show samples collected at each tool revolution. These dots were identified by sampling the displacement and velocity signals once per tool revolution using a laser tachometer (LT in the photo). Because the samples repeat, the cut is stable. An unstable result is shown in the bottom right. Here, the samples do not repeat with each tool revolution. This is chatter and produces the poor surface finish we observe. We obtain the elliptical shape because a new frequency was introduced into the dynamic system: the chatter frequency. This is the sound we hear.

When it comes to precision manufacturing, both CNC milling and CNC turning offer unique advantages. CNC milling is ideal for complex shapes and intricate designs, using rotating tools to cut materials, while CNC turning is best suited for cylindrical parts, using a rotating workpiece for precision. The right process depends on your specific project needs—whether it’s detailed shaping or producing high-precision, symmetrical components.

Let’s talk about milling stability. The top left figure depicts a down milling operation where the radial depth of cut linearly increases as the 20 mm diameter, 4 tooth endmill feeds horizontally to the right. The bottom left figure provides the stability limit for three radial depths: 1 mm (red), 10 mm (blue) and 20 mm (green). The latter represents slotting. Axial depth-spindle speed pairs above the limit are unstable; those below are stable. The selected spindle speed is 7000 rpm and the axial depth is 5 mm (black circle). The top right figure displays the tool vibration in the feed direction as the radial depth increases. The cut is initially stable (red box), but chatter occurs at the end (green box). The bottom right figure shows the frequency content for the stable (red) and chatter (green) conditions. For stable cutting at radial depths from 0 to 6 mm, we see the tooth passing frequency (7000*4/60 = 467 Hz). For chatter at radial depths above 14 mm, we see both the tooth passing frequency and the chatter frequency (520 Hz, near the natural frequency of 500 Hz).

Let’s talk about chatter in milling. The top panel displays a stability map that separates stable combinations of spindle speed and axial depth of cut (below the blue boundary) from unstable combinations (chatter above the boundary). Two sets of milling parameters are identified in the top panel. The red dot at {13000 rpm, 5 mm} represents a combination that exhibits chatter. The green dot at {16000 rpm, 5 mm} represents a stable combination. The bottom panel displays the tool vibration in the feed (x) direction for the two parameter sets. The red line is for the unstable {13000 rpm, 5 mm} pair and the green line is for the stable {16000 rpm, 5 mm} pair. The red and green dots follow the vibration as the cuts proceed. We see that the (red) unstable cut does not repeat; this gives the poor surface finish with chatter. The (green) stable cut repeats and gives the desired uniform surface finish. To generate the top panel and select stable milling parameters at the CAM stage, we: 1) measure the tool-holder-spindle dynamics; 2) select the force model based on the workpiece materials; and 3) compute the stability map.

Let’s talk about milling stability, force, and displacement. The middle plot displays a stability map that separates unstable (chatter) pairs of spindle speed and axial depth from stable pairs. The feed direction force and tool displacement are shown for three example pairs. The radial depth of cut is 5 mm (20 mm diameter, four tooth endmill) and the axial depth of cut is 5 mm for all three down milling cases. The red box displays results for 6000 rpm. We see the unstable spindle speed-axial depth pair gives large forces and displacements. We also see that the behavior does not repeat from tooth to tooth (these are the red dots). The blue box shows the unstable result for 9000 rpm. We observe similar behavior to 6000 rpm. The outcome is poor surface finish, premature tool failure, and potential catastrophic damage to the workpiece, tool, and spindle. The green box displays stable milling at 7500 rpm. The behavior now repeats with each tooth and the desired surface finish is obtained. This selection of stable machining parameters is possible when we know the vibration behavior of our cutting tool in its holder and spindle/machine.

Let’s talk about chatter in corners. Have you ever witnessed a spiral-out pocketing routine where the cut was stable most of the time, but “squeaked” in the corners? This is because the radial depth of cut increases from the commanded stepover to a full slot at these locations. The video shows a portion of a 50% radial immersion spiral-out, down milling pocketing routine for a 20 mm diameter endmill. We see that the cut is stable during the 10 mm radial depth part of the cut (0 to 2 mm distance). However, as the tool approaches the corner and the radial depth increases from 10 mm to 20 mm (2 mm to 12 mm distance), chatter occurs. The top panel shows the distance that the tool has traveled along the horizontal axis and the instantaneous radial depth along the vertical axis. We see that the radial depth increases from 50% radial immersion to a full slot in the corner. The bottom panel shows the feed direction force (Fx) as a function of time. The top and bottom panels are synchronized so that the moving dots indicate the same instant in time and cutter position. We have two options to avoid this corner chatter: 1) reduce the axial depth so that a slotting cut is stable – this decreases the material removal rate and increases machining time; or 2) choose a pocketing routine that maintains a constant radial depth – this is preferred because we can maintain the higher material removal rate for the higher allowable axial depth associated with the lower radial depth. There is also an advantage for tool wear with the latter option.

It's a cornerstone in manufacturing, capable of creating a wide range of shapes and features. How it Works * Rotary Cutting Tool: The heart of the machine, a milling cutter with multiple cutting edges, rotates at high speed. * Workpiece Movement: The workpiece is moved relative to the cutter, allowing the cutting edges to remove material. * Chip Formation: As the cutter interacts with the workpiece, it creates chips (swarf) that are carried away by coolant. Types of Milling Machines * Horizontal Milling Machine: The spindle is oriented horizontally. * Vertical Milling Machine: The spindle is oriented vertically. * CNC Milling Machine: Computer Numerical Control provides

Let’s talk about milling force and vibration. The movie shows the force (top panel) and tool displacement (bottom) for a down milling operation. The moving dots lets you correlate the dynamic force to the displacement. For this simulation, a 20 mm diameter endmill with four teeth and 30 deg helix angle is machining 6061-T6 aluminum. The axial depth is 4 mm, the radial depth is 5 mm (25% radial immersion), the feed per tooth is 0.1 mm, and the spindle speed is 5000 rpm. We see that only a single tooth is engaged in the cut at any given time and that the force increases from zero (no cutting) to the maximum value over a short interval for the down milling direction. We also see that the process repeats from one tooth to the next, so the cut is stable. However, we observe that even for stable (no chatter) machining the tool still vibrates. The results in the video are for the y direction, where x is the feed direction. If we look through the tool to the workpiece, the y direction is perpendicular to x in this plane. The tool axis is the z direction. The vibration plot shows the importance of considering the tool dynamics when selecting parameters in the CAM software.
