What is APKT1604PDSR-30?
APKT1604PDSR-30 is a milling insert that belongs to the APKT family of inserts from ISCAR, a leading manufacturer of cutting tools. The name of the insert indicates its shape, size, geometry, and grade. Here is what each letter and number means:
A: The shape of the insert is a parallelogram with an 85-degree included angle.
P: The rake angle of the insert is positive, which means it has a lower cutting force and a smoother chip flow.
K: The clearance angle of the insert is 11 degrees, which provides enough clearance for the cutting edge to avoid rubbing against the workpiece.
T: The tolerance class of the insert is T, which means it has a normal size tolerance and a normal hole tolerance.
1604: The size code of the insert is 1604, which means it has a 16 mm cutting edge length and a 9.45 mm inscribed circle diameter.
PDSR: The geometry code of the insert is PDSR, which means it has a right-hand cutting direction, a 1.78 mm corner radius, and an M chipbreaker. The M chipbreaker is suitable for medium machining conditions and provides good chip control and surface finish.
30: The grade code of the insert is 30, which means it is made of carbide with an AlTiN coating. The coating enhances the wear resistance and heat resistance of the insert, making it suitable for steel, stainless steel, cast iron, hard materials, non-ferrous metals, superalloys, and titanium.

You can also use the following formula to calculate the cutting speed:
V = πDN/1000
Where:
V is the cutting speed in m/min
D is the diameter of the milling cutter in mm
N is the spindle speed in rpm
Setting up the milling machine and tool holder
The next step is to set up the milling machine and the tool holder for the insert. You need to make sure that the machine is clean and stable, and that the tool holder is compatible with the insert. For APKT1604PDSR-30, you can use a 90-degree milling cutter with a 22 mm diameter and a 27 mm height. The tool holder should have a screw clamping system and a coolant hole. Here is an example of a suitable tool holder for APKT1604PDSR-30:
You need to mount the insert on the tool holder with a torque wrench and a screwdriver, and tighten the screw to the recommended torque value of 2.5 Nm. You also need to align the insert with the tool axis and check the runout and balance of the tool.
Adjusting the cutting parameters and feed rate
The final step is to adjust the cutting parameters and feed rate for the milling operation. The cutting parameters include the depth of cut, the width of cut, and the angle of entry. The feed rate is the distance that the tool moves per revolution of the spindle. You need to choose the optimal values for these parameters based on the material, the operation, and the desired surface finish. Here is a table that shows some general guidelines for these parameters:
