It is recommended that you climb the mill whenever possible.
Using a larger angular radius, it is the sharpest cutting edge in rough cutting applications.
When cutting width (WOC) is less than 50% of cutting diameter, compensate radial chip (see below).
Because our party shoulder tool to cut a real 90 °, they are a good choice for a wide range of completed application.
Cutting the grooves or reducing the pressure need to reduce the use of rough cutting knife; Use a finely tuned pitch cutter for lighter pressure cutting, or when feed prices can be maximized.
Most of DPA’s high-performance levels work best without a coolant. In most milling applications, the coolant produces a high thermal shock potential that produces immature, sometimes catastrophic failure. Use air pressure to provide adequate cooling and cuttings evacuation.
For long-term use, the core cutting tools of hard alloy are used to increase hardness and reduce flutter.
Optimized cutting performance
DPA’s high performance cutter works best when it is allowed to execute within the operational parameters of its design. Follow these steps to make sure you get the most out of your investments.
Refer to the feed and speed map (see below), and the recommended standard for each tooth (FPT) is provided per minute (SFM) and each tooth (FPT) according to the materials that need to be processed.
Use the following formula to determine your cutting tool RPM (RPM):
(SFM x 3.82)/tool Dia. = turn
For example, a diameter tool with a diameter of 900 SFM(900 x 3.82)/ 2 = 1720 RPM
Use the following formula to set it as machine tool: FPT x RPM xn (number of knives) = feed
A 5-flute player. “The (008). 008 x 1720)x 5 = 69 IPM
If the cutting width (WOC)< 1/2 cutter diameter, use the feed rate compensation diagram (figure below) to compensate the chip dilution.
After determining the WOC percentage of tool diameter, multiply the desired feed rate by the corresponding factor shown in the chart. This will be adjusted for each tooth (AFPT), resulting in the amount of true chip thickness required.
