Was ist ein Fräser?? How It Works in CNC Machining

A milling cutter is a rotary cutting tool used on milling machines and CNC machining centers. Most designs have multiple cutting edges that repeatedly engage the workpiece during rotation.

This guide explains how the tool works and how rotation, feed movement, Werkzeughaltung, and workholding interact during CNC machining.

Was ist ein Fräser??

The tool removes material from a workpiece as multiple cutting edges successively enter and leave the cutting zone during rotation. Most designs arrange these cutting edges around the tool body, although the exact geometry and mounting method depend on the cutter design and machine setup.

Im Gegensatz zu einem Einpunkt-Drehmeißel, it normally removes material with multiple cutting edges during each revolution.

How Does a Milling Cutter Work?

During milling, the machine rotates the cutter while creating controlled relative movement between the cutter and the workpiece. Each cutting edge engages the material for part of a revolution and removes a chip.

The combination of cutter rotation and feed movement allows the tool to follow the required machining path and remove material from the intended area of the workpiece.

Cutter Rotation and Cutting Edges

As the cutter rotates, successive cutting edges enter the cutting zone. Each edge removes a small amount of material during engagement and then leaves the workpiece before the next cutting edge enters.

This repeated cutting action allows multiple edges to share the cutting process. The number, Form, and arrangement of the cutting edges vary according to the cutter design, but the basic principle remains the same: rotating cutting edges progressively remove material from the workpiece.

Feed Movement Between the Cutter and Workpiece

Cutter rotation alone does not define the complete machined path. The milling machine also creates feed movement between the cutter and the workpiece.

Depending on the machine configuration, the table, Werkstück, Cutter, or several controlled axes may move. This relative movement allows the cutting edges to travel across the required area and create the intended machined feature or surface.

In der CNC-Bearbeitung, the machine program controls these movements so the cutter follows the required toolpath.

Maschine, Toolholding and Workpiece Relationship

The cutter does not work independently. The cutter, Maschine, toolholding system, and workpiece must function together during machining.

The milling machine or machining center provides controlled spindle rotation and axis movement. The toolholding system connects the cutter to the machine spindle and supports it during cutting, while the workholding system secures the workpiece in the required position.

Together, these elements create the cutting system that allows the cutter to follow the programmed path and remove material from the correct area.

What Is the Difference Between a Milling Cutter and an End Mill?

A milling cutter is the broader term for rotary cutting tools used in milling. An end mill is one specific family of milling cutters.

End mills typically use cutting edges along the outside of the tool and, depending on the geometry, may also cut with the end of the tool. Other milling cutter families can use different cutter bodies, mounting methods, cutting-edge arrangements, and geometries.

daher, every end mill is a milling cutter, but not every milling cutter is an end mill.

Zusamenfassend, “milling cutter” is the broader category, while “end mill” refers to one cutter family within it.

FAQ zu Fräsern

Was ist ein Fräser??

A milling cutter is a rotary cutting tool used on milling machines and CNC machining centers. Its cutting edges remove material during rotation and controlled movement relative to the workpiece.

How does a milling cutter work?

The tool rotates so that its cutting edges repeatedly enter and leave the cutting zone. Controlled feed movement between the cutter and workpiece allows those edges to remove material along the required machining path.

Does the milling cutter rotate or the workpiece?

In most operations, the cutting tool rotates. The machine creates the required feed movement by moving the table, Werkstück, Cutter, or a combination of controlled axes, depending on the machine configuration.

daher, the process combines rotation with controlled relative movement between the tool and workpiece.

Is an end mill the same as a milling cutter?

An end mill is one member of this broader rotary-tool family, which includes multiple cutter designs.

Different cutter families can use different tool structures, cutting geometries, and mounting methods depending on the machining requirement.

What is the difference between a milling cutter and a milling machine?

The cutter is the tool that removes material from the workpiece.

A milling machine is the machine tool that provides controlled rotation, positioning, and feed movement so the cutter can perform the machining operation.

In einfachen Worten, the milling machine controls the machining process, while the milling cutter performs the actual cutting.

Abschluss

A milling cutter is a rotary cutting tool that removes material as its cutting edges engage the workpiece during controlled rotation and feed. Understanding the relationship between the cutter, Maschine, Werkzeughaltung, and workpiece provides a basic foundation for understanding CNC milling.
