To remove machining marks from a 25" forged rim through coarse grinding, you'll need the right equipment and techniques. Here's a step-by-step guide to help you achieve this within 25 minutes:

Equipment and Materials Needed:
1. **Angle Grinder**: Preferably with variable speed settings.
2. **Coarse Grinding Disc**: Around 36-60 grit for initial removal.
3. **Protective Gear**: Safety glasses, gloves, hearing protection, and a dust mask.
4. **Clamping Tools**: To securely hold the rim in place.
5. **Work Surface**: A sturdy, stable workbench.

Step-by-Step Process:
1. **Preparation**:
**Clean the Rim**: Ensure the rim is clean and free from dirt and debris.
**Secure the Rim**: Clamp the rim securely on the workbench to prevent movement during grinding.
**Safety First**: Wear all necessary protective gear.

2. **Initial Grinding**:
**Set Up the Grinder**: Attach the coarse grinding disc to the angle grinder. Set it to a moderate speed to start.
**Begin Grinding**: Start with a light touch, moving the grinder evenly across the machining marks.
**Consistent Pressure**: Apply consistent pressure, but do not force the grinder, allowing the disc to do the work.

3. **Systematic Approach**:
**Work in Sections**: Divide the rim into sections and grind each section methodically.
**Smooth Transitions**: Blend the sections together to ensure a smooth and even surface.

4. **Check Progress**:
**Regular Inspection**: Stop occasionally to inspect the surface. Make sure the machining marks are being removed evenly.
**Adjust Speed/Pressure**: If needed, adjust the speed of the grinder or the pressure applied to optimize the grinding process.

5. **Final Touches**:
**Fine Grinding**: Once the major machining marks are removed, you might switch to a finer grit (80-120) to smooth out the surface further.
**Surface Check**: Run your hand over the surface to ensure it's smooth and free from significant imperfections.

6. **Cleanup**:
**Clean the Rim**: Wipe down the rim to remove any grinding dust or residue.
**Final Inspection**: Check the entire rim for uniformity and smoothness.

Tips for Success:
**Practice**: If you're new to grinding, practice on a scrap piece of metal to get a feel for the tool.
**Consistent Movement**: Keep the grinder moving to avoid creating deep gouges or uneven spots.
**Patience**: Don’t rush the process. Consistency and precision will yield better results than speed.

By following these steps, you should be able to effectively remove machining marks from a 25" forged rim within 25 minutes.
