• Set the workpiece zero point by using a touch probe or edge finder.

• Adjust the machine coordinates by inputting the desired values for each axis.

• Use the control panel or software interface to move the machine along each axis to ensure proper alignment.

• Perform test cuts or drills to verify the accuracy of the axis settings.

Q2. How to offset cnc vmc ? How to use work offset , geometry offset and wire offset
Ans. 
To offset CNC VMC, use work offset for part location, geometry offset for tool compensation, and wire offset for wire EDM machines.
• Work offset is used to set the part location in the machine coordinate system.

• Geometry offset is used for tool compensation, adjusting the tool path based on tool dimensions.

• Wire offset is used in wire EDM machines to compensate for wire diameter.

• Example: G54 is a common work offset used to

Q3. What is the cilindercity and Flatness? What is the mm or micron?
Ans. 
Cylindricity and flatness are measurements of how closely a surface or feature conforms to a perfect cylinder or plane.
• Cylindricity measures how closely a feature's axis aligns with a perfect cylinder.

• Flatness measures how closely a surface conforms to a perfect plane.

• Micron (µm) is a unit of measurement equal to one millionth of a meter, commonly used for precision measurements.

• Cylindricity and flatness are important ...read more
