What is the main purpose of stop blocks on a milling machine?

To enhance the appearance of the workpiece
To stop the workpiece from shifting under load
To prevent tool wear during operation
To control coolant flow during machining

The correct answer is: To stop the workpiece from shifting under load

The main purpose of stop blocks on a milling machine is to stop the workpiece from shifting under load. These blocks are essential for maintaining the position of the workpiece during machining operations, ensuring that it remains stable and secure while the cutting tool engages with it. This stability is crucial for producing accurate and precise cuts, as any movement of the workpiece can lead to poor quality finishes or incorrect dimensions. Additionally, having a secure workpiece reduces the risk of accidents that could arise from unexpected shifts, which could result in tool breakage, damage to the workpiece, or injury to the operator. By using stop blocks effectively, millwrights can enhance the safety and efficiency of their machining processes.
