Q2. Difference between upmilling and down milling??
Ans. 
Upmilling and down milling are two different types of milling processes used in machining.
• Upmilling, also known as conventional milling, involves feeding the workpiece against the rotation of the milling cutter.

• Down milling, also known as climb milling, involves feeding the workpiece in the same direction as the rotation of the milling cutter.

• In upmilling, the cutting forces tend to lift the workpiece, resulting in a l...read more

Q4. You are using ball nose end mill and need to reduce load on spindle, would you increase the tool dia and decrease the tool diameter?
Ans. 
Increasing the tool diameter and decreasing the tool diameter will not reduce the load on the spindle.
• Increasing the tool diameter will increase the load on the spindle as more material needs to be removed.

• Decreasing the tool diameter will also increase the load on the spindle as the tool needs to work harder to remove the same amount of material.

• To reduce the load on the spindle, other strategies such as reducing the ...read more

Q6. What is mql (minimum quantity lubricants) stands for??
Ans. 
MQL stands for Minimum Quantity Lubricants.
• MQL refers to a lubrication technique that uses a minimal amount of lubricant.

• It is commonly used in machining processes to reduce costs and environmental impact.

• MQL systems deliver a precise amount of lubricant directly to the cutting zone.

• The lubricant is atomized into fine droplets, ensuring efficient lubrication.

• Examples of MQL applications include drilling, milling, and t...read more
