- Imbalanced internal stresses: Materials inherently possess internal stresses. Wire cutting disrupts the equilibrium of these stresses, leading to deformation as the material attempts to restore balance.
- Workpiece structure: Workpieces with narrow and elongated shapes, as well as thin wall ketebalan, are prone to ubah bentuk during wire cutting.
- Lain-lain faktor: Bahan-berkaitan isu, heat treatment problems, design flaws, process planning, and improper clamping and cutting path selection can all contribute to workpiece deform.

Pencegahan Langkah untuk Workpiece Ubah Bentuk
Pra-potong kasar pemesinan atau tekanan pelepasan pemotongan: Conducting rough machining or using stress relief cutting techniques helps alleviate the residual stresses in the material before wire cutting, reducing the likelihood of deform.
Machining pilot holes: When cutting convex molds, machining pilot holes in the material before the actual cutting process helps maintain stress balance and prevents opening or closing deforms.
Mengoptimumkan memotong laluan: Properly arrangeing cutting paths is crucial. Start the cutting process near the clamped end, place the cutting segments at the end of the path, and position pause points closer to the clamped end to minimize deformation caused by improper cutting paths.
Multiple cutting pas: If workpiece deformation persists despite preventive measures, employing multiple cutting passes can be effective. This approach involves dividing the cutting process into several stages to achieve the desired accuracy while reducing deformation caused by internal stresses.
Menggabungkan multiple hold points: For large and complex-shaped workpieces, incorporating multiple hold points by adding several starting points throughout the cutting path helps distribute the cutting load and minimizes ubah bentuk.
