The Ultimate Guide to 5-Axis CNC Machining | Kingsbury
The axes on a Hermle 5-axis machine for example are represented by X, Y, Z, A and C. When standing in front of the Hermle, the X axis runs from left to right, the Y axis is the movement towards and away from you, and the Z axis moves the spindle up and down. These are the three linear axes on a traditional CNC machine.

Vibration and Chatter in Machining Operation
MACHINE-TOOL CHATTER Chatter is a self-excited vibration which is induced and maintained by forces generated by the cutting process. It effects surface finish, tool life, production rate and also produce noise. Chatter resistance of a machine tool is usually characterized by a maximum stable (i.e., not causing chatter vibration) depth of cut b lim.

Milling (size reduction and separation)
Milling (size reduction and separation) Generally, size reduction and size separation are combined to obtain powder with the desired particle size distribution (PSD) for acceptable flow and compressibility for downstream processing . The mechanical process of reducing the particle size of a solid is also called milling.

When the ECDs are installed onto the milling spindle, the mass–spring–damper model of the milling robot is developed as shown in Figure 12. The two ECDs that are used to damp the vibration in the x-axis are equivalent to one mass–spring–damper model. x 4 represents the equivalent displacement of the moving part of the ECDs.

Seguy et al.144, 145 studied the effect of a variable spindle speed on regenerative vibration of a machine tool in a high-speed milling process, and obtained an SLD under triangulation by a semi-discretization method. It was shown that periodic doubling chatter could effectively be suppressed by a spindle speed variation, although the technique ...
LATHE OPERATIONS - HNSA
a. General . The lathe is a machine tool used principally for shaping articles of metal, wood, or other material. All lathes, except the vertical turret type, have one thing in common for all usual machining operations; the workpiece is held and rotated around a horizontal axis while being formed to size and shape by a cutting tool.
