CNC Milling Machine

The CNC milling machine is an EMCO F1 CNC Mill produced in 1991 and has the following technical specification:

• Type: educational 3-axis vertical / horizontal milling machine;
• Machined parts maxim dimensions: 200 x 100 x 50 mm;
• Milling tools diameters: 3 – 15 mm;
• Tool changing: manual;
• Feed drive: step motors in X/Y/Z with a resolution of 0.01mm;
• Feed rate: 0 – 400 mm/min, rapid traverse 600 mm/min;
• Spindle speed: 0 – 2000 rot/min;
• Programming language ISO CNC – RS274D;
• PC communication: RS 232 – 300 bps.

The CNC machine is programmed using the ISO CNC language, known as G-Code. Moving instruction generate a line or an arc. Each moving instruction has as parameter the destination point coordinates. The moving instructions that generate circular trajectories include also the circle (arc) center coordinates.

CNC Machine

Using the I/O signals the following commands and states are available to the user:
Input signals:

1. vice closing/opening;
2. loading program;
3. program execution;
4. auto / manual mode.

Output signals:

1. vice state;
2. program execution over;
3. auto / manual mode.

The manual command of the machine is done only by using the control panel.
