Descriptions Of How To Use 3 Axis

A 3-axis finishing CAM module is instrumental in semi-finishing, finishing, and HSC milling of 3D surfaces, including molding, contouring and corner picking. It refers to the machine's ability to perform movement such as 3 different axis concurrently.

In most CNC machining, the manufacturers define their machine movement beginning with 3 primary axis X, Y, and Z. The Z is parallel to the tool spindle and has depth movement capability. X accounts for the horizontal movement, while Y represents the vertical movement.

Normally, the angle of the head can only be moved by up and down direction on the Z axis. It is also possible to use the conventional milling processes like end milling, slot milling, drilling, face milling, trepanning, chamfering, and others.

With that arrangement, the CNC machine is allowed to be programmed according to three axis encompassing a fully 3-Dimensional space.

Thus, with this type of CNC machining, you can transform 3D designs into various products that you can use on a daily basis. CAD designs such as chairs, tables, drawers, and cabinets are ideal for a three-axis CNC machining. You can also make 3D contour milling for milling out mould and die cavities.

Generally, the three-axis machining application feature contoured shapes from flat stock, sculptured surfaces, hole features, and tapered or draft surfaces.

Depending on the brand used, there is CAM software that supports all types of cutter-from a scriber to ball-end and even torus and end-mill cutters. When installed, the system automatically identifies the cutting zone limits and divides the components based on topological criteria.

The result will be a collision-checked NC program that can deliver even the strictest standard quality. There are HSC parameters used to calculate NC programs that are used in high-speed milling applications.

With a 3-axis cnc machine, you can move your machine on a 3 perpendicular axis, which is good for 90% of milling work that you will encounter. With the 3-axis, it is possible to complete multiple operations in a single part setup.

Three-axis milling enables you to perform castings or rough-machined parts. The latest version of this type of cnc machining minimizes air cutting because it can limit tool paths to the stock model, making it possible to achieve efficient tool paths more easily and quickly.

Moreover, it is often available with tool and pallet changers for high volume production. Some of the cutting tools that you can use with three-axis include end mills, slot mills, ball nose cutters, ball nose cutters, thread milling cutters, taps, and drills.

Also cutting tools like boring heads, reamers, tee slot cutters, slitting saws, dovetails cutters, and laser marking heads to make a large variety of machining operations are possible.

In working with the 3 axis CNC machining, it is important that you have read all manual that comes with it. Take special attention to notes and checklist provided. Take out the tool only when it is needed. After using it, ensure that you return it to where it is normally stored.

How are these machines used to set up the component datum (X0, Y0 and Z0 axis)??

How to Set Up a CNC Lathe Machine

http://www.ehow.com/how_5447873_set-up-cnc-lathe-machine.html

#
Step 1

djust chuck jaws to accommodate raw material. The jaws of the chuck, which hold the material, are usually adjustable with two screws on each jaw. Loosen each screw with the appropriate allen wrench and move each jaw to the required spot to allow the clamping force to hold the material without crushing it.
#
Step 2

Insert tooling required for the job. This may include boring bars, drills and insert holders for turning the outside diameters of the raw material. The holders vary in size and shape and are often held in place by screws in the tool turret.
#
Step 3

Teach each tool with the teaching arm. Slowly move the tip of each tool toward the teaching eye. When it touches that eye, you will usually hear a beep that signifies that the machine control knows where the tip of the tool is located for precision cutting.
#
Step 4

Set your zero, zero point. This is the starting dimension that will be used for the program to cut the raw material you are using. Bring a previously taught tool to the edge of the raw material and reset each axis, both X and Z to zero. The machine will use this point to base all of the other cutting dimensions.
#
Step 5

Program the lathe or call up an existing program that is in the machine. Most machine accept G code, which is the most common way of machining any parts in a CNC machine, including lathes. Many machinists use proprietary languages as they are sometimes easier to program on a lathe.

definition of machine zero:

* The position located at the farthest possible distance in a positive direction along the machine axes. This position is permanently set for each particular CNC machine.
* Learn more about machine zero in the class "GE Fanuc Mill: Locating Program Zero 270" below.
