How can the engraving machine slide the table?
In the numerical control woodworking engraving machine, the machining origin of the engraving material should be determined firstly, so as to establish an accurate machining coordinate system and consider the influence of the different sizes of the cutters on the machining. The precision of tool setting determines the machining accuracy of parts. At the same time, the efficiency of tool setting also directly affects the efficiency of engraving, which needs to be solved by tool setting.
A thorough understanding of the tool setting principle of the engraving machine is of great significance for the operator to keep a clear idea of the tool, master the operation of the tool setting and put forward new tool setting methods. The aim of the tool setting is to establish the workpiece coordinate system, and the intuitive way is that the tool setting is to establish the position of the workpiece in the engraving machine workbench, in fact, it is to seek the coordinates of the tool point in the coordinate system of the worktable. For engraving machines, in order to select the tool point before machining, the tool point is the starting point of the tool relative to the workpiece when the workpiece is machined by the engraving machine. The knife point can be located on the workpiece (such as workpiece design datum or datum), can also be located in the fixture or bench, or in a fixture or a point on the table, the size must be relationship with the workpiece positioning benchmark maintaining accuracy.
When the tool is adjusted, the point of the cutter should be coincident with the tool point. The so-called cutter point is the positioning reference point of the tool, and the cutter point is the tool point for the carver. The aim of the tool setting is to determine the absolute coordinate value of the tool point (or workpiece origin) in the coordinate system of the worktable, and to measure the tool position deviation of the tool. The accuracy of tool alignment is a direct influence on machining accuracy. In the actual processing of workpiece, the use of a tool, generally can not meet the processing requirements of the workpiece, usually use more cutting tools for processing. In the use of multiple knife processing, the tool change position unchanged, change the knife after the geometric position of cutting points will be different, which requires different tools to start processing in different starting positions, to ensure the normal operation of the procedures. In order to solve this problem, the engraving machine equipped with geometric position of the tool compensation function, using the geometric position of the tool compensation function, just prior to each knife relative to the measured a pre selected standard cutter position deviation, input to the engraving machine tool parameters correction column specified group number, using the T instruction in the process. You can automatically compensate the tool position deviation in tool path. The measurement of tool position deviation also needs to be done by tool setting.
