Functioning Axes of the Machining Center

X-Axis: Controls the cutting tool’s left and right movement along the horizontal axis.

• Allows for precise machining over the workpiece’s breadth.
• Regulates the workpiece’s machined parts’ dimensions and form.

Y-axis: regulates the cutting tool’s up and down direction.

• It makes it possible to create intricate curves and geometries.

Z-axis: provides the tool with vertical directional control.

• Measures the thickness of the shaved off skin and the depth of the cuts or incisions.
• Thrusting operations become more challenging as they also require penetration procedures, such as drilling and hammering.

Additional Axes (A, B, and C): Keep the state of workpiece or cutting tools by rotation.

• The A-axis helps with X-axis’ rotations and running the process of cylindrical features which is the main virtue of this axis.
• The B-axis provides the Y-axis movements as the rotation allows a different cutting angle.
• Rotating around the Z-axis is made easier by the C-axis, which is helpful for your machining on several sides.

Simultaneous multi-axis machining: This technique combines several axes’ motions to produce complicated objects.

• Reduces the need to move the workpiece, increasing efficiency.
• Complex features to be machined from several perspectives with a single setup.
