数控铣床编程100例简单图

Due to the limited space of the website, the editor cannot provide 100 CNC milling machine programming examples for the time being. But we can only provide some common CNC milling machine programming examples and explain their working principles. Later, 100 simple diagrams of programming will be released. The following are several common CNC milling machine programming examples:


1. Simple linear interpolation

N10 G00 X50 Y30; Rapid positioning to coordinate point (50, 30)

N20 G01 Z-5 F100 ; Cutting along the Z axis downward at a speed of 100 mm/min


Explanation: The program first uses the G00 command for rapid positioning to move the tool to the coordinate point (50, 30). Then the G01 command is used to move 5mm downward along the Z axis and cut at a speed of 100mm/min.


2. Cutting circular contours

N10 G90 G02 X50 Y30 I20 J0 F200 ; Cut a circle with a radius of 20 in clockwise direction at a speed of 200 mm/min


Explanation: This program first uses the G90 command to switch to the absolute coordinate system, and then uses the G02 command to cut a circle with a radius of 20 in a clockwise direction. X50 and Y30 are the coordinates of the center of the circle, I20 and J0 are the offsets relative to the center of the circle, and F200 is the cutting speed.


3. Cutting linear grooves

N10 G90 G01 X50 Y30 F200 ; Cut along the X axis to the coordinate point (50, 30) at a speed of 200 mm/min

N20 G91 G01 Y-10 ; Cut 10mm downward along the Y axis in relative coordinate mode

N30 G91 G01 X-20 ; Cut 20mm to the left along the X axis in relative coordinate mode

N40 G91 G01 Y10 ; Cut 10mm upward along the Y axis in relative coordinate mode

N50 G91 G01 X20 ; Cut 20mm to the right along the X axis in relative coordinate mode


Explanation: The program first uses the G90 command to switch to the absolute coordinate system, and then uses the G01 command to cut along the X axis to the coordinate point (50, 30) at a speed of 200mm/min. Next, use the relative coordinate method to cut a linear groove in a clockwise direction. Y-10 means cutting 10mm in the negative direction of the Y axis relative to the current position; X-20 means cutting 20mm in the negative direction of the X axis relative to the current position; Y10 means cutting 10mm in the positive direction of the Y axis relative to the current position; X20 means cutting 20mm in the positive direction of the X axis relative to the current position.


In addition, CNC milling machine programming has many complex and diverse applications, including circular interpolation, helical interpolation, tool switching, etc. These examples are just a few simple examples. If you have specific programming needs, it is recommended that you study CNC programming related textbooks or consult professionals to obtain more specific and practical programming examples.
