The most problematic aspect of microfabrication is that the processing conditions cannot be visually confirmed with the naked eye.

The biggest issue in microfabrication is that the processing conditions cannot be visually confirmed with the naked eye. The parts and shapes being processed are at a microscopic size, making it impossible to judge the cutting load from the sound of cutting or the way chips are produced. Similarly, if a tool breaks during processing, it is difficult to assess the situation due to the extremely small size of the tool. Furthermore, when dealing with micro components, the dimensional tolerances become nearly zero, and even a few microns of error can significantly affect the quality of the product. Naturally, finishing work by hand and measuring during the process are not possible, so the quality of the product cannot be determined until processing is complete. In other words, compared to precision machining where processing conditions can be visualized, microfabrication places an even greater demand on the experience and imagination of the technician, and the precision of the machines and temperature control required to achieve these results becomes even more stringent.

basic information

**Differences between Precision Machining and Micro Machining** - Micro machining cannot be visually confirmed with the naked eye. - The parts and shapes being machined are of microscopic size. → It is impossible to judge cutting load from cutting sounds or the way chips are produced. - Tools may break during machining. → The shape of the tools is also extremely small, making it difficult to assess the situation. - Dimensional tolerances are nearly zero. → A few microns of error can significantly affect the quality of the product. - Finishing work by hand or measuring during the process is not possible. → The quality of the product cannot be determined until machining is complete. - Compared to precision machining, where the machining situation can be visualized, micro machining demands even more from the technician's experience and imagination, and the precision of the machines and temperature control required to achieve these are even more stringent. **Commonalities between Precision Machining and Micro Machining** - Proper clamping and positioning during machining. - Precision management of the tools and machinery required for machining. - Calibration of measuring instruments for inspecting machined products. - Optimal machining conditions that ensure precision. - Technicians with experience and imagination capable of accurately judging issues during machining. - Environmental management, including temperature control and vibration countermeasures within the factory and machinery.
