Y axis machining and CX axis machining

 

Ø Y axis machining and CX axis machining is the most commonly used turning and milling compound machining method.

 

Ø For the machine tool equipment without Y axis, Y axis machining can be achieved by CX axis linkage fitting

 

But does not apply to all parts.

 

Ø CY axis machining and CX machining will not exceed three-axis linkage, but 5-axis machining is often used

 

Working method.

 

Ø Select different machining methods for different parts.

Y axis /CX axis machining parts classification

 

According to the movement of the machine tool during processing and programming mode, Y axis /CX axis processing parts usually can be divided

 

There are four types as follows:

 

Y axis processing parts

 

CX axis processing parts

 

CY/CX axis machining parts

 

Rotating milling parts

Y axis processing parts

 

Typical Y-axis machined parts, radial (flat bottom) type

 

Characteristics of cavity. C axis is not linked in the processing process, and XYZ is used

 

Three axis linkage can complete the processing.

 

Processing method: ordinary three - axis milling processing method

 

Note:

 

Ø The Y-axis must be used to complete the machining of this part.

 

Have high requirements for equipment.

 

Ø Can not use CX axis linkage to fit Y axis machining, no

 

Ensure the shape of the side wall of the cavity.

CX axis processing parts

 

Typical CX axis machined parts have a radial groove bottom surface of a circle

 

Cylindrical surface, and coaxial with the rotation axis of the part. In the process

 

C axis linkage is required without Y axis movement.

 

Processing method: five axis processing method

 

Note:

 

Ø Without Y axis participation, CXZ linkage is used to achieve the purpose of machining.

 

Ø Although the movement of the machine tool is simple, it needs to use five axes when programming

 

Processing method.

CY/CX axis machining parts

 

Tie irregular curved surface of the rotary body type parts, can make

 

Machining with CX axis or CY axis linkage.

 

Processing method: five axis processing method

 

CY axis machining: the ordinary five-axis machining method can generate the knife

 

Path. The Y axis floats on its own according to the surface shape of the part.

 

CX axis machining: in the parts to make a rotation shaft with the parts

 

A coaxial cylinder, which is used as a machining driving surface

 

The tool path is returned to the outer surface of the part to achieve CX axis machining.

 

Note:

 

When machining the local shape with CX axis, it is impossible to make and

 

Therefore, CX axis machining cannot be realized at this time.

 

It can only be processed with CY axis.

Rotating milling parts

 

Typical four axis rotary milling parts. In programming, can

 

Make a contour on the radial surface of the part, and then wrap the contour

 

Wrap to the surface of the part and use it as the machining drive line. programming

 

The tool path can be generated by a single drive line.

 

Processing methods: contour milling, keyway milling and other processing methods.

 

Note:

 

Ø When programming, the machining mode should be switched to the rotary mode.

 

Ø CX axis linkage processing, three axis processing method.

 

Ø Processing objects can only be wound after the line, usually used

 

In the fields of milling thread, radial lettering, etc.
