In conventional milling, you will see the cutter grind in the opposite feed direction. On the other hand, the cutter grind towards the feed direction in climb milling.

A peripheral milling operation also constitutes end milling. Before feeding the tool into and around the workpiece, it should first be positioned at a predetermined depth at the Z-axis.

Face milling operations are a machining process where the milling cutter is positioned parallel to the workpiece. This is because the process aims to grind the sides of the cutter on the surface of the workpiece.

Sidemilling

Z-milling is the type of milling operation that aims to remove material in planar levels perpendicular to the fixed tool axis.

Facemillingvs endmilling

Once the face milling process has begun, and the spindle starts spinning, feed the face mill on top of the workpiece. In this phase, you’ll be using the end of the cutting tool for material removal.

Peripheral milling operations involve using an end mill or shell mill, even if the removal of material from a workpiece mainly happens on the sides of the cutting tool.

The feed rate of the face mill is HIGHLY DETERMINED by the number of teeth on the cutting tool, material of the workpiece, the depth of the cut, rigidity of the tool, and force applied by the vise or fixture.

In face milling, the rotating axis of the cutter is positioned perpendicularly on the surface machined to achieve a FLAT and SMOOTH top face.

While both aim to remove material from a workpiece with a rotating milling cutter, face milling and peripheral milling still have KEY DIFFERENCES, specifically in how they perform their tasks.

Liberty Machine Works, Inc. seeks review of an adverse decision of the Tax Court in which tax deductions were denied with respect to a profit-sharing plan for its salaried and clerical employees. The facts which presented the issue and the reason for the determination by the Tax Court are set forth in its opinion. 62 T.C. 621. The decision of the Tax Court is correct and its judgment is

In peripheral milling, end mills remove material from a workpiece at the periphery during the machining process, unlike face mills that remove material at the top to produce flat surfaces.

NOTE: Make sure that the machine spindle, which holds the cutting tool, is rotating at the right RPM (revolutions per minute).

Generally, face milling involves general face milling, high face milling, heavy-duty face milling, and finishing with wiper inserts.

The teeth on the milling cutter will distribute the chip load, while the teeth of the cutter on the periphery completes the cutting job.

Like in face milling, you’ll be able to achieve your objective depending on the accuracy of feed rates and cutting speeds, depth and positioning, as well as clamping force.

At this point, you already know the difference between face milling vs. peripheral milling, and you’re probably ready to head to your workshop to start milling. But before you do, allow me to give you some useful tips!

When face milling, I highly suggest using milling cutters designed for facing, such as fly cutters and shell mills. But if you’re aiming for a different finish, an end mill will help significantly.

Now that you already know what face milling and peripheral milling are, it’s time to compare the two machining processes. I’ll list all their differences down in 5 points:

Face milling and peripheral milling operations are two terms you might encounter when dealing with the different machining processes.

Now you know how to differentiate the two milling operations. And hopefully, you were able to understand how these processes work.

Wait no further and start milling your workpieces. As you head back to your workstation, remember to follow the tips listed above!
