Why Are 5-axis Robots Better than 3-axis Robots?

Why Are 5-axis Robots Better than 3-axis Robots?


Three-axis Machining Mode
 
Three-axis machining of  3-axis robots is performed by linear feed axes X, Y and Z. Machining features: The cutting tool direction remains unchanged during the whole cutting path movement. The cutting state of the tooltip can't be perfect in real-time.
 
3+2 Axes Machining Method
 
Two rotating shafts first fix the cutting tool in an inclined position, and then the feed shafts X, Y and Z are used for processing. This machine tool is also called the positioning five-axis machine tool. The rotary work plane in space can be defined by 3+2 axes machining (such as turret or turntable). In this work plane, 2D or 3D machining operations can be programmed.
 
Five-axis Machining Mode
 
Five-axis machining consists of linear interpolation motion of feed axes X, Y, Z and any five axes of rotation A, B and C around X, Y, Z.
 
Machining features: The cutting tool direction can be optimized during the whole path movement, and the cutting tool can move linearly at the same time. In this way, the best cutting state can be maintained in the whole path.
 
5-axis Can Process 28 Parts at the Same Time
 
How can the advantages of the five-axes machine be reflected? Here is an example of processing 28 parts at the same time. Through the design of turntable and fixture, and the combination of three machining surfaces of parts in a five-axis machining program, the purpose of reducing cycle time is achieved.
