Description

Numerical control machining method for cutting blanks in set

Technical Field

The technology belongs to the field of numerical control machining, and particularly relates to a machining method for numerical control machining of woolen suit cutting.

Background

Processing axial vaulting pole support is according to only processing a part on a square stock in the past, and originally processing a part is in order to avoid the clamp plate, because the clamp plate occupies very large tracts of land, under the unchangeable people's circumstances of woollen size and dimension, because cutter centre gripping length is the high sum of part degree of depth and clamp plate, the cutter centre gripping is long, and the rigidity is weak, and the process velocity is slow, and still pay attention to the position of clamp plate, avoid hitting the clamp plate, because the woollen is little, so slide caliper rule hardly measure the part.

Disclosure of Invention

The invention aims to provide a processing method for numerical control processing blank suit cutting, which does not change the size of a part, changes the processing technology, mills through grooves on both sides of the blank of the part in the length direction, presses a pressing plate at the positions of the through grooves, shortens a processing cutter, improves the rigidity, improves the processing speed, releases a large area of the surface, and can process a part according to the actual measurement of the size of the rest blank. The technical problems that a cutter in the prior art is long in clamping, weak in rigidity and low in machining speed, the position of a pressing plate needs to be noticed during machining, the pressing plate is prevented from being collided, and the caliper is difficult to measure due to small rough materials are solved.

The technical scheme adopted by the invention is as follows:

a numerical control processing method for cutting a woolen cloth comprises the following steps:

1) milling through grooves at two ends of the part blank in the length direction, wherein the number of the through grooves is four, and the four through grooves are distributed on two sides of an upper processing surface and two sides of a lower processing surface of the part blank;

2) pressing the pressing plate at the position of the through groove, and mounting a cutter;

3) when the plane size of the part blank can contain two finished products, the positions of the finished products need to be planned on the part blank, and the finished products can be arranged in a staggered or opposite mode to process two finished products at one time;

4) establishing a coordinate system, setting a cutter point on the upper surface, installing a phi 16R3 cutter to open a rough full mold, and leaving a finish machining allowance on one surface;

5) installing a cutter with the diameter of phi 10R3 to finish the side wall and the web plate, and then installing a cutter with the diameter of phi 16R0.5 to clean the root;

6) after the measurement is qualified, unloading the rough material of the part;

7) rotating the unloaded rough material of the part by 180 degrees around the Y axis, reestablishing a coordinate system, arranging a phi 16R3 cutter opening rough full model with a cutter point on the bottom surface, reserving a 0.5mm finish machining allowance on one surface, and arranging a phi 10R3 cutter finishing side wall and a web plate;

8) and installing a knife with the diameter of phi 16R0.5 for cutting to obtain a finished product.

The finishing allowance in the step 4) is 0.5 mm.

The lower part of the pressing plate is provided with supporting legs, the upper part of the pressing plate is a pressing plate extending towards the blank of the part, the joint of the pressing plate and the through groove is of an equilateral trapezoid structure, the width of the joint of the pressing plate and the through groove is reduced, and the short edge of the joint of the pressing plate and the through groove is of an equilateral trapezoid structure.

The pressing plate is pressed and fixed by bolts.

The invention has the beneficial effects that:

1. a large amount of areas on the surface are released, the size of the wool is fully utilized, part suit cutting is fully realized, the problem of part suit cutting is solved from two angles of improving positioning stability and saving space, the space of the wool is fully utilized as far as possible to suit and cut out as many parts to be processed as possible, and the cost of raw materials is greatly reduced.

2. The novel positioning mode shortens the clamping length of the cutter, greatly improves the rigidity of the numerical control machining cutter head in the machining state through positioning, and greatly improves the service life and the machining efficiency of the cutter head.
