Abstract
The invention discloses a long chip material chip breaking processing method, wherein a spiral groove is firstly lathed on the surface of a part, and the depth A of the spiral groove is less than the allowance ap of the part; then, the part is finish-cut by a finish tool, the finish machining amount T is equal to the part allowance ap-the depth A of the spiral groove, and when the part is cut through the spiral groove, the chip in the spiral groove is thinner than the front chip and the rear chip so as to form a chip breaking. The invention can automatically break chips in the finish machining process, thereby effectively avoiding the formation of long chips, and avoiding the influence of the long chips on the surface precision of a product and the service life of a cutter due to the winding of the long chips on parts and the cutter.
Description
Technical Field
The invention belongs to the cutting processing technology, and particularly relates to a chip breaking processing method for a long-chip material.
Background
In the traditional soft material cutting process of aviation aluminium and the like, long cutting chips can be generated, if the cutting chips are wound on a part, the surface precision of a processed product can be influenced, and if the cutting chips are wound on a cutter, the cutter can be broken, so that the service life of the cutter is shortened. With the development of part materials, lightweight soft materials such as aviation aluminum and the like are widely applied in a large scale, and the optimization of a cutting mode process becomes a key point of attention of people, particularly the problem of long chip winding, and needs to be solved urgently.
Disclosure of Invention
The invention aims to provide a long chip material chip breaking processing method, which can effectively break long chips into chips without winding parts and cutters.
In order to solve the technical problems, the invention adopts the following technical scheme:
a long chip material chip breaking processing method, a, turning a spiral groove on the surface of a part, wherein the depth A of the spiral groove is less than the allowance ap of the part;
b. and (3) performing finish machining cutting on the part by using a finish machining tool, wherein the finish machining quantity T is equal to the allowance ap of the part and the depth A of the spiral groove, and when the part is cut through the spiral groove, the cutting chips in the spiral groove are thinner than the front cutting chips and the rear cutting chips so as to form the broken chips.
The step length of the spiral groove turning is 0.5-1.5 mm.
By adopting the chip breaking processing method for the long-chip material, the spiral groove is turned on the surface of the part, and then the part is normally finished, so that when the part is cut in a chip breaking area passing through the large spiral groove, the thicknesses of front and rear chips are different, the chips in the spiral groove are thinner, and the chips are easier to automatically break at the position, so that the length of the chips is effectively controlled, and the influence on the surface precision and the service life of a cutter due to the winding on the part and the cutter is avoided.
Drawings
The invention is described in detail below with reference to the following figures and detailed description:
FIG. 1 is a schematic view of the present invention for forming a spiral groove in the surface of a part.
FIG. 2 is a schematic diagram of the present invention for fine machining based on spiral grooves.
FIG. 3 is a schematic view of a chip breaking region of the present invention.
Detailed Description
The chip-breaking processing method of the long-chip material disclosed by the invention is shown in figures 1-3, and mainly comprises the following steps:
a. turning a spiral groove 2 on the surface of a part 1, wherein the depth A of the spiral groove is smaller than the allowance ap of the part as shown in figures 1-2; the spiral groove 2 adopts a large step length, namely the groove width is larger than the cutter feed amount in normal turning, the machining efficiency is high by adopting the large step length, the length of scrap iron is favorably controlled, and the step length (namely the groove width) of the spiral groove is preferably designed to be 0.5-1.5mm through repeated calculation and test.
b. And then, performing normal finish machining on the part by using a finish machining tool according to the required feeding rotating speed and other parameters until the finish machining of the part is finished, wherein the finish machining amount T is equal to the part allowance ap-the depth A of the rotary groove.
In the finish machining process, the spiral groove 2 becomes a chip breaking area (see fig. 3) for cutting, namely when the finish machining cuts through the spiral groove 2, chips in the spiral groove 2 are far thinner than front and rear chips, so that the chips are easy to break at the position and are automatically broken along with the progress of the chips, the formation of long chips is effectively avoided, and the phenomenon that the long chips are wound on parts and tools to influence the surface precision of products and the service life of the tools is avoided.
However, those skilled in the art should realize that the above embodiments are illustrative only and not limiting to the present invention, and that changes and modifications to the above described embodiments are intended to fall within the scope of the appended claims, provided they fall within the true spirit of the present invention.
