Medium wire cutting programming teaching: Master the processing parameters of 100 thick materials!

Medium-speed wire cutting technology plays a key role in the manufacturing industry, especially when processing thick materials. This article will introduce the medium-speed wire cutting programming teaching in detail, with a special focus on the processing parameter setting on 100 thick materials, aiming to help readers master this advanced processing skill.

1. Basics of WEDM Programming

Before mastering WEDM programming, you first need to understand the basic concepts and terms, including coordinate system, tool compensation, cutting speed, pulse width, pulse interval, etc.
Mastering these basic knowledge is the basis for WEDM programming.

2. Material preparation and clamping
Before wire cutting, make sure the selected material meets the processing requirements and clamp the workpiece correctly to ensure processing stability. The processing of 100 thick materials requires special attention to the firmness of the clamping to avoid vibration and deformation during processing.

3. Parameter setting of medium wire cutting
3.1 Cutting speed (mm/min)

Cutting speed refers to the distance that the medium-speed wire cutting machine cuts along the surface of the workpiece in a unit time. For 100mm thick materials, it is recommended to cut at a moderate speed. Too fast may cause the wire to wear too quickly, and too slow may affect the processing efficiency. In general, the cutting speed can be selected between 300~500mm/min.

3.2 Pulse width (mm)
Pulse width refers to the width of the discharge channel, which affects the width of the cutting line. For 100mm thick materials, the selection of pulse width should be determined according to the precision requirements of the workpiece and the discharge current. Usually, the pulse width can be set between 0.1~0.2 mm

3.3 Pulse interval (mm)
The pulse interval refers to the distance between two discharges, which affects the processing accuracy. When processing 100 thick materials, the selection of pulse interval should take into account the hardness and shape of the workpiece. Usually, the pulse interval can be set between 0.15~0.25 mm and fine-tuned according to actual conditions.

3.4 Cutting height (mm)
The cutting height refers to the distance between the cutting wire and the workpiece surface during processing, which affects the stability and finish of the processing. When processing 100 thick materials, the cutting height can usually be set between 0.15 and 0.25 mm. The specific value needs to be determined according to the shape and requirements of the workpiece.

4. Preparation before processing
Before the wire cutting process, the following preparations need to be made:
Check the machine tool and wire status: Ensure that the machine tool is operating normally and the wire is not broken or damaged.
Set the coordinate origin: Set the origin of the processing coordinate system according to the actual position of the workpiece to ensure the accuracy of the processing position.
Adjust the clamping: Ensure that the workpiece is clamped stably to avoid vibration and deformation during processing.
Preheat the workpiece: For some special materials, preheating treatment can be performed to improve processing stability.

5. Precautions during processing
Real-time monitoring of processing status: During processing, timely observe the processing status of the workpiece surface to ensure processing quality
Regularly replace the blade wire: The blade wire is a consumable part and needs to be replaced regularly after a certain period of processing to maintain processing quality
Pay attention to the discharge current: The choice of discharge current needs to be determined according to the material and thickness of the workpiece. Excessive current may cause the workpiece surface to burn.

6. Summary
Mastering the programming of medium wire cutting and correctly setting the processing parameters is essential for processing 100mm thick materials. Through reasonable parameter settings, fine processing operations and stable machine tool performance, high-precision and high-quality processing effects can be obtained on 100mm thick materials. In actual operation, processing personnel need to continuously accumulate experience and flexibly adjust parameters to cope with workpieces of different materials and shapes to ensure the stability and efficiency of medium wire cutting processing.
