Dosage and cutting tool life are closely related. In preparing the cutting parameters, you should first pick a reasonable period engraving machine tool, cutting tool and reasonable deadline should be based on the principle of optimization. Usually divided highest production rate and lowest cost cutter knives period of two period, the former based on the principle of a single piece of work to determine the least, which is based on the principle of the process to determine the lowest cost.

    Thinking the selection tool life can be the following:

    Depending on the tool clutter level, production costs and sharpening to pick. Messy and high precision tool life should be selected higher than the single-edged knives.

    About machine folder indexable cutting tool, because the tool change time is short, in order to give full play to its cutting, progressive power production, tool life alternative to a low level, usually take 15-30min.

    About loaded knife, tool change and adjustment of multi-tool knife messy machine tools, combined machine tools and automated processing tools, tool life should be selected to be higher, in particular, should ensure that the tool reliability.

    A workshop production rate within the constraints of the progress of the whole process of the workshop production rate, the tool life of the process to be selected to be less; when a certain unit time in charge of the process to the whole plant expenses M is large, the tool life It should also be chosen to be lower.

    When finishing large, to ensure that at least the end of one pass, to prevent the cutting halfway tool change, tool life and precision parts shall determine the appearance of roughness.
