CNC flame cutting machine tool compensation knowledge
First, what is a knife compensation? If we say that it is a knife compensation, I think many non-professionals certainly do not know what this is? In fact, there is another name for cutter compensation in the CNC cutting industry: slotting compensation. Speaking of this, I think many people know it. Flame cutting is based on the kinetic energy of thermal energy and gas to process materials. According to the specific shape and process requirements of the workpiece, it must be cut at different positions and in different cutting methods and directions. Due to thermal deformation during cutting of the CNC flame cutting machine, the lead-in and lead-out lines are not necessarily a straight line and may be circular arcs or broken lines, so the establishment and retraction of the tool offsets cannot be established only on the straight line segments like cold working. The establishment of actual toolpaths is not the same as cold machining. Special planning and handling are required.

Cold-cut tool radius is a fixed value, and flame cutting "tool radius" is reflected in the flame of the material cut into the gap, the width of the slit is related to many factors, and in the processing of the same part, the width There may also be changes. Assuming that the width of the kerf does not change during the machining process, according to the technological features of the NC flame cutting machine, the realization of kerf compensation during thermal cutting is studied. For unified calling, slotting compensation is still called tool radius compensation, or simply tool compensation.
Second, the detailed process of knife compensation 1), according to the processing characteristics of the flame cutting, the introduction, lead lines have to be offset. The principle of the elimination of knife compensation is the same as the establishment. In the graphical expression, the cancellation of tool compensation is the reverse process of the establishment of tool compensation.
2) The input interface of the tool compensation module of the tool compensation execution is the data queue obtained after decoding optimization, and the output interface is the data queue for interpolation preparation. Usually the output queue is longer than the input queue length. Tool compensation establishment establishes the starting point of cutting. During tool compensation execution, when processing the current curve, the information of the next curve of the person is always read first, and the transfer vector is calculated after the connection type and transfer type are established, and the transfer vector is calculated. , The programmed trajectory vector, tool radius vector, and other information synthesize a new tool center movement trajectory. In the middle, there will be new connection segments generated, so that the location of the preheat and stop codes in the system will be affected. And there must be a transfer vector between the fast move instruction and the machining instruction. A small connecting line segment will appear in the new trajectory generated by the vector, and it is determined whether the position is fast moving or linear interpolation according to its position, and the corresponding M code is placed in an appropriate position according to the process requirements.
