A manual, 3B programming: we must first understand what is 3B? The 3B refers to the first B X is the representative of the second axis, third axis B on behalf of Y, B on behalf of the X and Y axes of the longest one axis, for example: manually compiled a line OA as shown in figure: if OB=2mm, BA=, 1mm, then draw some A in the 4 one quadrant, and in the X and Y axis as the limit, so that the X axis is 2mm, the Y axis is 1mm. The 3B program is composed of B2000, BB1000, BB2000 (XL1). Because the longest side is to be taken as the X axis and in the positive direction of the X axis. The other direction is the same, as long as it is the direction of the longest axis.

 

If a circle is made up, the knife is in the circle and in the positive direction of the X axis, so the X axis is 5mm and the Y axis is 0.

 

Programming: B5000 BO B5000 (XL1) BBB5000XL1. (the following is BBB).

 

The longest axis of B5000 BO B2000 (YNR1) is a circular arc, so the closed arc is 4 R.

 

BBB5000 (XL3). (the line of the back knife is opposite to the direction of the dividing line).

 

For example, figure (2) is in the direction of the circle outside the circle and to the X axis, so that:

 

BBB5000 (XL1)

 

B5000 BO BBB20000 (YNR3)

 

BBB5000 (XL3)

 

The above is an example of reverse machining, while the direction of the circular arc is SR1, SR2, SR3 and SR4, such as diagram (3), (4).

 

If a square is made up

 

A square is a closed pattern made up of a line segment. It is simple to distinguish the direction of the line. A rectangle is 5 * 10. At the same time, the knife is out in the hole in the direction of the Y axis. When the knife is out of the knife, a line segment is divided into two segments, and a square is made up of seven lines, and the programming (1) is 10mm.

 

BBB2500 (YL2) BBB2500 (YL2)

 

BBB5000 (XL3) BBB5000 (XL1)

 

BBB5000 (YL4) BBB5000 (XL2)

 

(1) BBB10000 (XL1) (2) BBB1000 (XL3)

 

BBB5000 (XL2) BBB5000 (XL4)

 

BBB5000 (XL3) BBB5000 (XL1)

 

BBB2500 (XL4) BBB2500 (XL4)

 

If the knife is outside the square hole and is programmed (2), all of them are processed in the direction of counterclockwise.

 

Two, automatic programming: in the reverse direction of molybdenum wire processing, when the standard compensation, reverse clockwise machining molybdenum wire in the inside, clockwise machining molybdenum wire on the outside.

 

6. line cutting clearance compensation:

 

When the molybdenum wire is 0.18mm and the spark position is 0.02mm, the standard compensation is the addition of the spark position of the molybdenum wire diameter and the further division by 2 is (0.18+0.002) /2=0.1mm..

 

When the line cuts the inner hole, the molybdenum wire is inside, when the wire cutting the shape of the molybdenum is outside.

 

For example, when a line is cut in an inner circular hole, a single side enlargement of 0.02. (2) is required (1) to narrow the 0.02.

 

Requirements (1) compensation for a single side amplification by standard compensation, and the required compensation, that is, 0.1-0.02=0.08.

 

Request (2) the compensation obtained by the standard compensation for a unilateral reduction, that is, 0.1+0.02=0.12.

 

When the line cuts a shape square, it requires (1) single side amplification of 0.02. (2) to narrow the 0.02.

 

At this point, it is the opposite of the line cut hole.

 

Requirements (1) for standard compensation and single side amplification compensation equal to the required compensation, it is 0.1+0.02=0.12.

 

The requirement (2) for the standard compensation and reducing the unilateral reduction is equal to the requirement of compensation, and it is 0.1-0.02=0.08

 

7. mold structure:

 

Generally, dies can be divided into three main categories: compound die, single die and continuous die. The compound die and Dan Chongmo are all made up of the shear gap. The punch is reduced to the gap, the fixed plate should be tight with the punch die, that is to reduce the gap as the punch die.

 

The continuous mode is divided into two small species: one is the flying mold. The two is the continuous punch of the punching.

 

Die is to step away from the flying material model refers to a product, cut off excess wool finally draws its material products, flying shear clearance is generally 0.06-0.07/mm. punching die refers to the step jump cut out the last hole products, can also be said as the single die, will cut out the whole product the same is to cut the gap. The standard punch out.

 

Compensation for 8. wire cutting

 

For example, the rough unilateral reduction of 0.3. then the molybdenum wire in the graphics.0.3-0.1=0.2.

 

The fine public narrow 0.05. itself is enough compensation, and the molybdenum wire is still out of.0.1-0.05=0.005.
