Victor Vcenter-A5

3+2 machining uses the A and C rotary axes to position the workpiece at a fixed angle, then executes the cutting program in 3-axis linear motion at that fixed orientation. Simultaneous 5-axis interpolates all five axes (X, Y, Z, A, C) continuously during cutting, enabling the tool to follow complex curved surfaces while maintaining a consistent tool-to-surface angle. The Vcenter-A5 supports both: 3+2 is available on any 5-axis machine as a positioning mode, while simultaneous 5-axis interpolation requires the Fanuc 30i-B5 or Heidenhain TNC 640 with the appropriate 5-axis software options active.

The Vcenter-A5 is compatible with all major CAM systems that output 5-axis G-code or direct Fanuc/Heidenhain post-processors, including Mastercam, Hypermill, PowerMill, NX CAM, Fusion 360, and SolidCAM. For production 5-axis work, a purpose-built 5-axis post-processor verified on the specific machine is essential — Victor's application team or the dealer can provide or recommend tested post-processors for major CAM platforms. Post-processor verification with a known test part is strongly recommended before committing the machine to production programs.

Trunnion table (A+C) 5-axis places the rotary motion in the table rather than the spindle head. This keeps the spindle in a fixed vertical orientation, which simplifies thermal stability and spindle speed management. The limitation is that workpiece size is constrained by the trunnion table diameter and weight capacity. Swivel-head (B+C or A+B) 5-axis keeps the table fixed and tilts the spindle, allowing larger, heavier workpieces. For smaller precision components (medical, small aerospace), trunnion is generally preferred; for large structural parts, swivel-head or gantry 5-axis is more appropriate.

RTCP (Rotary Tool Center Point, also called TCPC or TCP) is a control function that automatically compensates for the offset between the tool tip and the rotary axis center as the A and C axes move. Without RTCP, a 5-axis program would need to manually calculate and compensate for this geometry in every line of G-code, making CAM programming prohibitively complex. With RTCP active on the Fanuc 30i-B5, the CAM system programs in part coordinates and the control automatically handles the kinematic transformation. RTCP is essential for practical simultaneous 5-axis machining and is standard on the Vcenter-A5.

Victor Taichung sells through authorized dealers in North America, Europe, and Asia. North American buyers should contact Victor's North American importer for current dealer listings and demo availability. Victor's 5-axis machines have been exhibited at IMTS and other North American trade shows, providing exposure to the US market. As with most Taiwanese brands, service coverage in North America depends on regional dealer quality — thorough dealer evaluation before purchase is particularly important for 5-axis machines where application support and programming assistance are frequently needed.
