CNC machining is not only used for
large-volume parts processing, but also for small-volume parts and
high-precision parts. CNC machining is flexible and highly automated. It is
especially suitable for machining curves with complex contours, curved parts,
and complex boxes with a large number of holes and grooves. The prismatic parts
are used in many varieties and small batches. Processing can achieve high
economic benefits.

The processing of cnc processing technology is basically the same as ordinary processing, but it has its own characteristics. Therefore, when designing the numerical control machining process of the parts, it is necessary to follow the CNC machining flexibility and high degree of automation. It is especially suitable for processing curves with complex contour shapes, curved parts, and complex boxes with a large number of holes and grooves. In the case of multi-variety and small-volume production, the use of CNC machine tools can achieve high economic benefits.

The cnc machining center determines the
tool point and the tool change point. The tool point is the starting point of
the tool movement relative to the workpiece during NC machining. Since the
program is also executed from this point, the tool point is also called the
program start point or the starting point. The choice of the tool point
position should be considered first when programming.

When the machining accuracy is not high,
some surfaces on the workpiece or on the fixture can be used directly as the
tool face. When the machining accuracy is high, the tool point should be
selected on the design basis or process reference of the part, such as hole
positioning. For the part, it is more appropriate to take the axis of the hole
as the tool point.

The tool point must have a certain
coordinate relationship with the positioning reference of the workpiece to
determine the relationship between the machine target and the workpiece
coordinate system. The choice of the tool point should facilitate the
calculation of the coordinate values and make the tooling convenient.

When the tool is set, the tool point should
be coincident with the tool point. The so-called knife position, for the flat
end mill refers to the intersection of the tool axis and the tool bottom; for
the ball end milling cutter is the ball center of the ball head; for the
turning tool is the tool tip; for the drill bit is the drill tip; The wire
electrode cutting machine tool refers to the focus of the wire electrode axis
and the part surface.

Pingtejing CNC machining center reminds
everyone that when changing the tool during the machining process, the tool
change point should be specified. The position of the tool change point should
be based on the principle of not hurting the workpiece, fixture and machine
tool during tool change. set up. Do not blindly change the props, which may
cause damage to the equipment.
