What are you most afraid of when engaging in CNC machining? That is choosing the wrong tool path, which will lead to scrapped parts or very low efficiency. Many people think that as long as the machine tool is good enough, it is enough. In fact, programming strategy is the key. Just today, I’m going to talk about those tool path types that give masters a headache but are inseparable from CNC milling tool path types , to help you avoid the pitfalls.

Secrets of commonly used paths

Although G code is boring and boring, it controls how the machine tool moves. Common paths include following the periphery, parallel milling, and radial. Each path has its own unique application scenario, and it cannot be adopted just by selecting it.

Novices often have difficulty distinguishing the differences between them, resulting in uneven surface quality. Knowing these basic types is the first step towards becoming a master of CNC milling tool path types , and it is also a key point in ensuring accuracy.

The magic of following your surroundings

This path is suitable for processing irregular contours. The tool will travel close to the edge of the part. It can obtain a good finish on the side wall, which is especially suitable for the finishing stage after roughing.

For complex shape conditions, manual programming is basically impossible to complete, but CNC can handle it relatively easily. With the reasonable settings around the instrument, it can be ensured that the tool always runs according to the established trajectory, thereby reducing the occurrence of tool empty running and thus improving the overall processing efficiency.

Choice of parallel and radial

The CNC milling tool path type using parallel milling is like cutting tofu in parallel. It is suitable for machining regular large planes. The efficiency is relatively high and the work is very uniform. However, residual material is easy to be left in the corners.

The radial shape is a situation of spreading from the center to the outside, or converging from the outside to the inside. It has significant advantages in the process of processing the cavity. It can prevent the tool from staying at the center point for too long, thus protecting the tool life.

The power of the spiral knife

Traditional vertical cutting is prone to tool breakage, while spiral cutting, like using screws when drilling, cuts in slowly. This cutting method is more uniform in force, and the pressure generated by the spindle and the tool is much smaller in comparison, so it is extremely suitable for deep cavity processing.

A large number of current machine tools support such intelligent path setting ① which should ensure the accuracy and accuracy of the workpiece being processed. By adjusting the spiral diameter and step distance, and following the relevant content, you can find the optimal parameters that best suit the current material and tool, thereby achieving twice the result with half the effort.

Path decision accuracy

What directly affects the dimensional accuracy and surface roughness of the final part are different path types. If you choose the wrong path, even if the machine tool has extremely high precision, you will not be able to produce high-quality products.

This requires programmers to be familiar with the characteristics of various materials. The processing path parameters of aluminum alloy are completely different from those of stainless steel. Blind application of templates will definitely lead to catastrophic consequences.

Summary of practical experience

Don't just focus on theory, try different path combinations more than actual operations. Pay attention to the various conditions of tool wear and the effect of chip removal, and continuously adjust relevant parameters, so that you can accumulate experience.

Remember, there is no best path, only the most suitable path. Flexible selection based on part shape, material hardness and machine tool performance is the core competitiveness of CNC machining.
