So a good experiment, push the envelope. I ended up doing some tests for myself. Therefore depending on the diameter of the tool, if the RPM and number of cutter edges stay the same chip load will increase with a larger diameter cutter, thus the feed rate will also increase. Variable speed dial allows to match the speed based on the application requirement. Therefore if chip load remains the same, and feed rate increases, either the RPM and or number of cutting edges must increase to maintain the recommended chip load.When calculating the feed rate for any material the chip load is therefore one of the most important factors to be taken into account because the chip load determines the amount of material that each tooth will remove, plus the load that each tooth will have to take. xref 2. resipsaphotographer 5 yr. ago. Would love your thoughts, please comment. Lets first calculate the circumference of a few simple bits sizes for example: 1-inch diameter bit = 3.142 x 1 in.

(Please refer to the manufacturers recommendations and keep in mind the speeds they suggest are maximum): Generally, the rim speed will be around 100 to 120 miles per hour. Speeds and feeds are the cutting variables used in every operation and vary for each tool based on cutter diameter, operation, material, etc. If an extra long router bit is being used, the chip load should be decreased.For most material that you will be cutting on a CNC router you will typically set the RPM between 12000 and 24000, and adjust your feed rate to obtain the required results. A standard router bit spins clockwise. Generally you should choose the option which includes both such as mixed and the software will choose what to use.
