The Background and Significance of NC Turn-milling Machine Tool

CNC milling machine is developed on the basis of ordinary milling machine. The processing technology of the two is basically the same, and the structure is somewhat similar. But the CNC milling machine is an automatic processing machine controlled by the program, so its structure is also very different from the general milling machine.

Its main functions are basically the same.

1, point control function

This function can realize the machining of holes with high mutual position accuracy.

2, continuous contour control function

This function can realize the interpolation function of straight lines and circular arcs and the processing of non-circular curves.

3. Tool radius compensation function

This function can be programmed according to the size of the part drawing, without considering the actual radius size of the tool used, thus reducing the complicated numerical calculation during programming.

4. Tool length compensation function

This function can automatically compensate the length of the tool to meet the requirements of adjusting the length and size of the tool in machining.

5, proportion and mirror processing function

The proportional function can be performed by changing the coordinate values of the programmed machining program according to the specified proportion. Mirror machining is also called axisymmetric machining. If the shape of a part is symmetrical about the coordinate axis, then as long as one or two quadrants are programmed, the contours of other quadrants can be realized by mirror machining.

6. Rotation function

This function can be performed by rotating the programmed machining program at any angle in the machining plane.

7, subroutine call function

Some parts need to process the same contour shape repeatedly in different positions. The machining program of the contour shape can be used as a subroutine, which can be repeatedly called at the required position to complete the machining of this part.

8, macro program function

This function can use a general instruction to represent a series of instructions to realize a certain function, and can operate variables, making the program more flexible and convenient. -
