How to determine the machining allowance of machining

    In the industry, we can see a lot of Shenzhen machining, using mechanical equipment to process, to make our various parts, or accessories, then in the process of processing, how to determine the machining allowance for machining .

    First, look-up table method. According to the machining allowance data provided in the relevant manuals, the machining allowance will be determined after correction in combination with the actual production situation of our factory. This is a method widely adopted by various factories.

    Second, empirical estimation method. Determine the machining allowance based on the experience accumulated by the technologists. Generally, in order to prevent the waste from being too small, the estimated margin is always too large. It is often used for single-piece and small batch production.

    Three, analytical calculation method. According to the theoretical formula and certain experimental data, the factors affecting the machining allowance are analyzed and calculated to determine the machining allowance. This method is more reasonable, but requires comprehensive and reliable test data, and the calculation is also more complicated. Generally, it is only used in factories where the materials are very expensive or in a few large-scale and mass-produced factories.
