VMC Training – Programming, Setup, CNC Milling & Precision Machining
Develop practical skills in Vertical Machining Centre operation, CNC milling programming, G-code, M-code, machine and work coordinates, tool-length offsets, work offsets, Automatic Tool Changer operation, face milling, slots, pockets, profiles, drilling, tapping, machine setup, inspection and troubleshooting.
What Is VMC and Why Is It Used in Manufacturing?
A Vertical Machining Centre is a CNC machine in which the spindle is vertically oriented. It is widely used for milling, drilling, tapping, boring, pocketing, profiling, contour machining and precision component manufacturing.
Programming + Setup + Machining
Effective VMC operation requires more than knowing G-code. The operator or programmer must understand machine axes, coordinate systems, tooling, workholding, tool offsets, work offsets, machining parameters, program verification and component inspection.
NCVT VMC Training connects these topics into one practical manufacturing workflow.
Plan → Program → Setup → Verify → Machine → Inspect
The goal is to understand how engineering drawings, cutting tools, CNC programs, machine settings and measurement work together to produce a finished component.

VMC Milling vs CNC Turning
Both are CNC technologies, but the cutting mechanics and typical component geometries are different.
Rotating Cutting Tool
The cutting tool rotates while the job is clamped to the machine table. Typical operations include face milling, slots, pockets, profiles, contours, drilling and tapping.
Rotating Workpiece
In CNC turning, the workpiece rotates while the cutting tool machines cylindrical features such as diameters, grooves, tapers and threads.
