The numerical control machine tool chip breaking method has the beneficial effects that the numerical control machine tool parameters are utilized to compile a macroprogram to realize the chip breaking hole machining in a pause mode, namely, the chip breaking is realized by pausing for a preset time after each step depth is machined until the hole machining is completed.
Description
Technical Field
The invention relates to the technical field of machining, in particular to a machining method of a pause chip breaking hole.
Background
At present, due to the fact that the number of tough materials to be machined is increased gradually, the difficulty of part machining is increased, particularly in the hole machining process, cutting chips can be wound on a cutter, so that the cutter is not cooled sufficiently, and meanwhile the cutting chips can rotate along with the cutter, and the surfaces of parts are scratched. Conventional tool-retracting chip-breaking machining methods are now commonly used to avoid the above problems.
Fig. 1 is a schematic diagram of a conventional backspacing chip-breaking machining method, in operation, a tool 1 cuts a stepping depth d1 at a cutting speed, then rapidly backs to a safety plane a, then the tool 1 rapidly reaches a position 0.2mm above the previous backspacing position again, then cuts a distance d1+0.2mm at the cutting speed, and then backs to the safety plane a, and then the tool is repeatedly fed and retreated until the machining is completed. With a diameter ofFor a hole with a total depth d of 30mm, for example, the safety plane a is set to be 1mm from the surface of the part 2 and the cutting edge is about 3mm, the tool 1 will cut 30+3+1 to 34mm in total, if the step depth d1 is set to be 0.5mm, the tool 1 will be retracted 34/0.5 to 68 times, and the total cutting depth will reach 47.6mm plus 0.2mm reserved each time. If the cutting speed is set to 30mm/min, the retraction speed is 5000 mm/min, and the total processing time is about 2 minutes. Therefore, the traditional chip-breaking machining method has the defects of long time consumption, low machining efficiency and the like.

s2, stopping the cutter for a preset time;
and S3, repeating the steps S1 and S2 until the cutter is machined in the part to a preset total depth, and finishing machining.
Preferably, a macroprogram is programmed with numerically controlled machine tool parameters to control the movement of the tool.
More preferably, the macro procedure is as follows:
the numerical control machine tool chip breaking method has the beneficial effects that the numerical control machine tool parameters are utilized to compile a macroprogram to realize the chip breaking hole machining in a pause mode, namely, the chip breaking is realized by pausing for a preset time after each step depth is machined until the hole machining is completed.

Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and are not intended to limit the present invention.
In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
As shown in figure 2, the invention provides a method for machining a pause chip breaking hole, which controls the machining motion of a cutter 1 in a part 2 by compiling a macro program according to parameters of a numerical control machine tool, and mainly comprises the following steps:
s1, the cutter 1 downwards processes a stepping depth d1 in the part 2;
s2, stopping the cutter 1 for a preset time t;
and S3, repeating the steps S1 and S2 until the cutter 1 is machined to the preset total depth d in the part 2, and finishing machining.
In a specific embodiment of the present invention, let d1 be 0.5mm, t be 0.1s, cutting speed v be 30mm/min, and d be 34mm, where d can directly specify the assignment of parameters, and d1, t, and v can all be assigned by variable specification parameters. The traditional backspacing type chip breaking method is replaced by stopping for a preset time t to break chips, so that the moving distance of the cutter 1 can be effectively shortened, the machining time is reduced, and the influence of the chip breaking on the cutter 1 is avoided.
The specific macro procedure is as follows:
also in terms of diameterFor example, holes with a total depth of 30mm are processed in only 75 seconds, and compared with the traditional backspacing chip-breaking type processing method, each hole processing process can save 45 seconds, the processing time is greatly shortened, and the processing efficiency is improved.
In conclusion, the numerical control machine tool chip breaking method has the beneficial effects that the numerical control machine tool parameters are utilized to compile a macro program to realize the chip breaking hole machining in a pause mode, namely, the chip breaking is realized by pausing for a preset time after each step depth is machined until the hole machining is completed.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
