1. Overstrual work room:
reason:
1. Screw knife.
2. Inappropriate IT of the operator.
3. The cutting margin is uneven. (For example: 0.5 on the side of the curved surface and 0.15 below)
4. Inappropriate cutting parameters (such as: too large tolerance, SF adjustment too fast, etc.).
improve:
1. Principle of using a knife: it can be large or small, and it can be short or long.
2. Add an angle cleaning program and try to keep the margin evenly (the margin between the sides and the lower surface is consistent).
3. Reasonably adjust the cutting parameters and make circles at the corner of a large margin.
4. Using the SF function of the machine tool, the operator displays the speed to obtain the best results in the cut of the tool-tool.
2. Divided questions:
reason:
1. The operator is inaccurate when it works manually.
2. There are burrs around the mold.
3. The central stem has magnetic properties.
4. The four sides of the mold are not vertical.
improve:
1. Manual operation must be carefully checked several times and the division must be at the same point and at the same height as possible.
2. Use the oil stone or the file to remove the burrs around the mold and wipe it with a cloth, and finally confirm with your hands.
3. Demagnetize the stick before dividing the mold (a ceramic stick or another can be used).
4. Check if the four sides of the mold are perpendicular (the verticality error is large and you must review the plan with the most adjustment).
3. Knife problem:
reason:
1. The operator is inaccurate when it works manually.
2. Tool tightening is incorrect.
3. The blade on the flying knife is wrong (the knife flying itself has certain errors).
4. There is an error between the R knife, the flat -bottomed knife and the flying knife.
improve:
1. Manual operation must be carefully checked several times and the knife must be at the same point as possible.
2. When installing the tool, blow it with an air gun or wipe it with a cloth.
3. When the blade on the flying knife is measured, a blade can be used when the blade rod and the lower surface of the light.
4. A separate knife procedure can avoid errors between the flat knife R and the flying knife.
5. If you want to learn the UG programming, you can add the qq 304214709 group to receive UG learning equipment and courses.
4. Collisides programming:
reason:
1. The safety height is insufficient or not adjusted (when the G00 is fed quickly, the knife or the mandrel strikes the room).
2. The tool on the program sheet and the actual program tool are badly written.
3. The length of the tool (leaf length) and the actual processing depth on the program sheet are poorly written.
4. The depth Z axis number and the actual Z axis number on the program list is poorly written.
5. The adjustment of the coordinates is incorrect during the programming.
improve:
1. A precise measurement of the height of the part also guarantees that the safety height is greater than the part.
2. The tools on the program list must comply with the real program tools (try to use the automatic programs list or the list of image programs).
3. Measure the actual depth of the treatment on the part and clearly write the length and length of the edge of the tool on the program sheet (generally, the length of the 1.0 mm pliers of the air).
4. Take the real Z axis on the room and write it clearly on the program sheet. (This operation is generally written by manual operation and must be checked several times).
5. collision operator:
reason:
1. Alignment error of the Tool of the depth Z axis.
2. The number of keys and manipulations in the segment is incorrect (such as: the single number has no entry department, etc.).
3. Use the bad knife (like: the D4 knife is used to treat it with the D10 knife).
4. The program is false (such as: A7.NC VA A9.NC).
5. The steering wheel is in the wrong direction during manual operation.
6. Press the wrong direction when you feed manually (like -X Press + X).
improve:
1. When adjusting the tool to the axis of depth Z, you must pay attention to the place where the tool is. (lower surface, upper surface, analysis surface, etc.).
2. Check several times once the number of touch and maneuver in the minute ended.
3. When installing the tool, you must repeatedly check the program sheet and the program before installing it.
4. The procedures must be followed one by one.
5. When using manual operation, the operator must strengthen the operating competence of the tool-tool.
6. When you move manually, you can first lift the Z axis to the room and move it.
6. Surface precision:
reason:
1. The cutting parameters are unreasonable and the surface of the surface of the room is rough.
2. The cutting edge of the tool is not sharp.
3. Tool tightening is too long and the blade is too long to avoid space.
4. It is not good to remove the shavings, blow out air and rinse oil.
5. Programming tool method (you can try to consider the smooth movement).
6. The room has burrs.
improve:
1. Cutting parameters, tolerances, margins and speed power parameters must be reasonable.
2. The tool forces the operator to inspect and replace it regularly.
3. During tightening tools, the operator must tighten as much as possible and the blade should not be too long to avoid air.
4. For the descending cut of the flat knife, the R knife and the round nose knife, the speed adjustment should be reasonable.
5. Piece has land: our machine tools, tools and tool methods are directly linked. We must therefore understand the performance of the machine tool and finish the edges in the shape of a burr.
Daguang focuses on providing solutions such as precision CNC machining services (3-axis, 4-axis, 5-axis machining), CNC milling, 3D printing and rapid prototyping services.
