1, give yourself a goal to learn something every day.
2. When you want to study, please turn off QQ and all chat tools and study with 100% concentration.
3. Read and study the information in the forum carefully. Remember to soak up the information under the forum all day, and there is no substantive learning action.
4. It is the same to learn any software. First of all, we must have the necessary professional basic knowledge. For example, mechanical drawing is one of the most important basic disciplines.
5, learn the cam part should also have certain cutting knowledge and processing experience (including ordinary machine tool processing experience).
6. Learning theoretical knowledge is as important as learning practical experience, and some basic learning is essential. Often beginners only focus on learning sample tutorials. Thus ignoring the theory. They should be combined. In order to achieve the best learning effect.
7. Learning masterCAM is not conducive to learning other software at the same time, because it often happens that learning several softwares at the same time leads to the confusion of software application functions. Learning software requires a single breakthrough.
8. Remember to learn everything in the sample text. As a result, I didn't learn anything well Everyone knows the fur.
Use Mastercam's experience, functions and skills.
1.2D milling
Mastercam programming is characterized by quickness and convenience. This feature is particularly prominent in 2D tool path.
The series connection between 1 and Mastercam is very fast, as long as the curve you extract is continuous. If it is discontinuous, it is easy to check where there is a breakpoint. A simple method is to use the analysis command, set the tolerance to the minimum value of 0.00005, and then select a seemingly continuous curve. There is a problem here. It can be done quickly by curve fusion.
In short, in Mastercam, as long as the outline edge, step line, hole, groove line, etc. The machined parts are solved first, and the next cam operation is very convenient.
2. Because Mastercam's 2d serial connection is convenient and quick, it is always easy to select all the contours of the workpiece you process at one time. A great advantage is that the starting point of series connection is where the feed arc (usually set) is located.
3. When processing runner or multiple curves, there are often multiple curves to choose from. Because there is no need to offset the tool radius, in Mastercam, you can use the frame selection method to select them at one time.
Second, three-dimensional surface trenching:
Opening thickness of Mastercam
1, gong, copper or male die, it is best not to cut the knife on the workpiece. Mastercam can easily choose a point as the cutting point every time. Of course this point is outside the workpiece, but don't deviate too far from the workpiece. This function of Mastercam is well designed, with fewer tools and high efficiency, which can basically ensure that the cutting point is at the same point, so the machining is safer.
2. If the gong cavity is used in this way, or in the low-lying place of the gong, it is very important to cut the knife, and the smaller the angle, the better. 3 to 5 degrees is suitable for copper, and no more than 5 degrees is suitable for steel. I think 2 degrees is the best. The processing is smooth and there is no big noise.
3. Important Settings: If all input attempts fail, please select Skip. Otherwise, when milling can't screw or align the cutter, it will go straight down.
4. One trick: When digging a groove on a surface, check "Follow Boundary" in the parameter column of spiral cutting. This function may not be used by many people. But the effect is greatly good. You can let the tool go down to the deepest part of the workpiece and cut around instead of going straight in!
3. Machining of 3D runner:
Note that it is 3D instead of 2D; This is steep 3D instead of flat 3D.
1. In Mastercam, if it is a runner of a planar 3d surface, the function of machining with 3d curve is the best. But if the damage is large, or like a wave. It is necessary to project the center line of the 3d wheel onto the surface through projection processing. Then through negative correction for many times, it is processed to the radius depth of ball end mill.
Four, about parallel milling:
Mastercam has the highest utilization rate of parallel milling. Disadvantages: A steep side will not be milled well.
Mastercam has an excellent tool feeding method, which is scallop in surface finishing. This tool path in Mastercam is very easy to use, and some people report that the calculation is time-consuming. But if the error is set to a diaosi, the calculation speed is not slow, and the effect after processing is already very good. I have compared, a little more tolerant, a little more rigid things look the same.
V. About Angle:
Mastercam must remove corners (i.e. corners) from the outside to the inside. This is preset in Mastercam.
Six, about the call of tools:
In Mastercam, the parameters such as cutter diameter, R angle, revolution and feed speed are set when the cutter is established. When you call this knife in the future, you don't need to set the revolution and feed speed every time.
Seven, parallel milling depth setting:
1, Mastercam, surface machining can also define the milling depth, which is an excellent function!
2. In some cases, you may not want the ball cutter to be milled so deep, or the calculation shows that the lower plane is milled, as long as it is slightly shallow. In Mastercam, you can get good control by adjusting the cutting depth to ensure that the tool will not touch the lower plane.
Eight, about the problem of flat knife correction:
When milling surfaces, Mastercam (it is said that X version can be used, but I haven't tried it) and UG can't negatively correct the flat cutter. I think the best way is to subtract the unilateral negative correction *2 from the actual size of the knife when programming. Some people say that adding an R angle to the knife can play a negative correction role. This is really said and done without studying hard.
It's not impossible to add an R angle, but it depends. If the slope is not large, you can do this, and add an R angle as small as possible; However, if this method is still used for the surface with large inclination angle, the actual machined size will be much smaller than the expected size, and the larger the R angle is set, the greater the error will be. It doesn't matter if it's thicker or smaller. If it's a back mold, I'm afraid it's not good.
Nine, about the number of revolutions:
With a knife, of course, the number of revolutions is higher. But it doesn't have to be very high, so that the machine tool can't breathe. Can you imagine? I can use a common machine tool and a 0. 1 knife I grind to process a steel stamp embossing die with a length and width of less than 2mm, and only need 4000 revolutions! The feed speed is not low, and sixteen punches only take one hour. Most people probably think that they need a engraving machine to make tens of thousands of turns. For NC programming, many methods have to be discovered by yourself. Don't follow other people's and popular methods and become timid, afraid to open up new methods.
X. post-processing:
Mastercam is really a popular software, so it is widely used. In the early years, when the NC programming industry was in full swing, how many people didn't use Mastercam? Mastercam programming speed is fast, and the nc program after processing is also very safe, which is worth using with confidence. I have used three different machine tools for numerical control programming, and none of them have problems because of the post-processing of Mastercam. Except for special models of machining centers, general computer gongs can successfully read CNC programs generated by Mastercam! Novices generally don't have to worry about post-processing. This is amazing!
