Скачать или смотреть Okuma OSP-xxxx Series CNC: ⚙️ Variable VOVR[0] to Adjust Rapid Feedrate G00

The video explains how to adjust the rapid feedrate (G00) on Okuma OSP CNC machines using a specific variable called VOVR, which stands for Variable Override. This feature allows programmers to dynamically control various override values, including rapid movement, feedrate, and spindle speed, directly within the NC code. By setting VOVR[0] to a percentage, operators can temporarily reduce the machine's G00 speed, proving beneficial for tasks requiring enhanced safety or precision, such as during machine setup or when working near obstacles. It's crucial to remember that these VOVR settings override physical dial adjustments and must be manually reset to revert to original speeds.

The VOVR variable on Okuma OSP controls like the OSP-E100L is used to programmatically control override values, including rapid feedrate override. Here's how it works and how you can use it:
🔧 What is VOVR?
VOVR stands for Variable Override. It allows you to set override values via NC code, which is especially useful when you want to control feedrate, spindle speed, or rapid movement dynamically during program execution.
⚙️ Using VOVR to Adjust Rapid Feedrate (G00)
✅ Syntax Example

Plain Text
VOVR[0] = 50

This sets the rapid override to 50% of the machine’s maximum G00 speed.
📋 Override Indexes
VOVR[0] → Rapid override
VOVR[1] → Feedrate override
VOVR[2] → Spindle speed override
You can use these in your program to temporarily reduce speeds for safety or precision.
🧠 Typical Use Case
This is useful during setup, near clamps, or when approaching tight areas.

Plain Text
VOVR[0] = 25 (Set rapid to 25%)
G00 X100.0 Z50.0
VOVR[0] = 100 (Restore rapid to 100%)

🛑 Important Notes
VOVR values are percentages (0 to 100).
They override the physical dial settings temporarily.
You must reset them manually if you want to return to full speed.
