What are the causes of cracking in high pressure water jet cutting ?

During the high pressure water jet cutting equipment process, it was found that some workpieces were cracked to varying degrees, and these workpieces all had one thing in common, that is, the thickness exceeded 40 mm. Is it possible that a workpiece of this thickness is particularly prone to cracking when cutting? This issue requires further analysis.

The workpiece to be cut is generally heat treated such as quenching, so it is bound to contain residual stress inside, and the thickness of the workpiece determines the magnitude of the stress. When the thickness is small, the stress along the top of the crack is in a plane stress state, and plastic flow is easy to occur at this time. However, as the thickness increases, the toughness will gradually decrease, and eventually physical fracture will occur due to the difficulty of plastic flow.

In view of this, the high pressure water jet cutting equipment method should be carefully selected when cutting thicker workpieces. The cracking of the workpiece has nothing to do with the performance of the high pressure water jet cutting equipment process itself, so don’t doubt its ability. So it depends on the material you want to cut. WIN-WIN waterjet can give you many waterjet cutting solution to choose for your busniess.
