準備工作：在進行切割之前，確保準備好所需的工具和設備，如電鋸、切割機、量具、眼鏡等。同時，清理工作區域，確保周圍沒有雜物和障礙物。

Preparation work: Before cutting, make sure to prepare the necessary tools and equipment, such as electric saws, cutting machines, measuring tools, safety glasses, etc. At the same time, clean the work area and ensure that there are no debris or obstacles around it.

測量和標記：使用量具測量門套的尺寸，并在石塑門套上做出標記，以指導切割的位置和長度。使用直尺或者模板來確保標記的準確性和一致性。

Measurement and marking: Use measuring tools to measure the size of the door jamb and make markings on the stone plastic door jamb to guide the cutting position and length. Use a ruler or template to ensure the accuracy and consistency of markings.

選擇合適的切割工具：根據門套的厚度和材質，選擇合適的切割工具。對于較薄的石塑門套，可以使用手持電鋸或者切割機進行切割。對于較厚的門套，可能需要使用更強力的電鋸或者的切割設備。

Choose the appropriate cutting tool: Based on the thickness and material of the door pocket, choose the appropriate cutting tool. For thinner stone plastic door jambs, a handheld electric saw or cutting machine can be used for cutting. For thicker door jambs, it may be necessary to use a stronger electric saw or professional cutting equipment.

操作：在進行切割之前，戴上眼鏡和手套，確保自身。將門套穩定固定在工作臺上，以防止移動或晃動。在切割過程中，保持穩定的手勢和均勻的切割速度，避免突然用力或者過快的切割。

Safe operation: Before cutting, wear safety glasses and gloves to ensure personal safety. Stabilize and fix the door cover on the workbench to prevent movement or shaking. During the cutting process, maintain stable gestures and uniform cutting speed to avoid sudden force or excessive cutting speed.

切割技巧：根據標記的位置，將切割工具沿著門套的邊緣或者指定的線條進行切割。對于直線切割，可以使用導軌或者直尺來保持切割的準確性和平直度。對于曲線或者彎曲的切割，需要更加小心和耐心，逐步進行切割，以保持切割線的平滑和精確。

Cutting technique: According to the marked position, use the cutting tool to cut along the edge of the door jamb or the specified line. For straight cutting, guide rails or rulers can be used to maintain the accuracy and straightness of the cutting. For curved or curved cutting, it is necessary to be more careful and patient, gradually cutting to maintain the smoothness and accuracy of the cutting line.

整理和修整：完成切割后，檢查切割線的質量和準確性。如果有需要，可以使用砂紙或者銼刀對切割邊緣進行修整和打磨，使其更加平滑和整齊。

Sorting and trimming: After completing the cutting, check the quality and accuracy of the cutting line. If necessary, sandpaper or a file can be used to trim and polish the cutting edges to make them smoother and more neat.
