Introduction: During the processing of the engraving machine, the margin and cutting amount are all set in advance, so for the “elderly people” this is very easy to accomplish, and for the newcomers, it may seem more difficult. Edited for everyone to introduce how to set.
First, the setting of the machine allowance
The setting of the finishing allowance for the engraving machine is mainly to compensate for dimensional errors and contour errors that exist in the machining. The greater the error, the greater the machining allowance left, the general settings are as follows:
1. The machining allowance for rough machining of metal materials is 0.05 to 0.10. When the aspect ratio of the tool is greater than 5, the larger value is selected.
2. The machining allowance for rough machining of non-metallic materials is 0.15-0.25, and the larger value is selected when the aspect ratio of the tool is greater than 5.
3. The machining allowance for semi-finishing of metal materials is 0.02~0.04. When the aspect ratio of the tool is greater than 5, the larger value is selected.
4, surface engraving machine engraving, parameter surface surface margin.
5, plane engraving, the parameters for the engraving of the side margin, in the processing should be adjusted according to the specific circumstances.
In general, the machining allowance is mainly reserved for the subsequent processing, in order to ensure the surface quality of the final part.
Second, the setting of the cutting amount during the fine machining
When finishing machine is finishing, the common cutting amount is generally divided into the following two kinds:
1, shallow eating, large feed, fast knife. This type of solution is often used in metal finishing. The prerequisite for use is a large area of processing with a tool diameter of 4 mm or more. The advantage of this method is that it is efficient when machining a large area and the tool can be ground.
2, eat deep, small feed, fast knife. This scheme is generally used in rough metal finishing. The precondition for use is that the processing area is small and the tool diameter is 4 mm or less. The advantage of this method is that it is efficient when machining small areas, and the tool cost is low.
Third, trial cut carving machine processing method steps
Understand how the above machining allowance and cutting amount are set. Then we start the actual operation and determine the appropriate parameters and dosage.
1. Find the relative cutting performance of the material similar to the test cut material.
2. Set the cutting amount and processing parameters according to the relative cutting processing performance. At this time, each parameter should be set conservatively.
3. Machining on the CNC machine to observe the machining status. The cutting status at this time may be very light, and there may also be abnormal conditions such as high vibration and dull sound.
4, adjust the processing parameters and cutting amount, to achieve the ideal cutting state and cutting efficiency, and then determine the open rough process.
5, set a certain amount of knife, processing a simple plane, to see whether the rough surface meets the requirements, and then determine the amount of precision machine engraving knife.
Hao Chao's above-mentioned machining allowance and cutting amount setting can only be used as a reference. The actual production and processing process has a wide range of products. Therefore, it is necessary to sum up experience in actual operation and constantly adjust the parameter settings during processing. Get the best setting.
