CNC milling machining for complicated parts
1. CNC milling machine
One of the commonly used CNC machining methods can control the movement of multiple coordinate axes (3-5 axes) at the same time, and keep them in a predetermined movement relationship, so as to process the workpiece into a certain shape part.
The CNC milling machine can mill all kinds of parts surface, groove cavity, plane contour, three-dimensional contour and complex surface parts.
Process treatment: the processing route is determined, as shown in the figure
Milling route, as shown in the figure:
Complex cavity ring type plus, as shown in the figure:
Cavity machining with islands, as shown in the figure:
"Line cutting method" processing surface as shown:
Three-coordinate and five-coordinate machining of the curved surface, as shown in the figure:
Programming features and commonly used commands: linear interpolation, arc interpolation, polar coordinate interpolation, parabolic interpolation, spiral interpolation, involute interpolation, spline interpolation, etc.
Use proportional zoom to realize the mirroring function, as shown in the figure:
Coordinate commands: G68, G69, G17/G18/G19 G68, X-Y-Z-R-; rotation center (X, Y, Z), R rotation angle, reverse (positive) G69 cancel. as the picture shows:
G54~G29 commands, the coordinate points are shown in the figure:
Instruction format, as shown in the figure:
Spiral interpolation instruction, as shown in the figure:
Example of milling programming, as shown in the figure:
Sales programming example two, as shown in the figure:
