Devfoam programming for hot wire cnc cutting machine

Hot wire cnc cutting machine is used for cutting architectural moulding,foam profiles,foam package etc.The machine takes devfoam software to draw and control for cutting.We introduce here with devfoam software as following.

When the EPS profiles are processed, the hot wire first stops at the reference point, and then is controlled by the devfoam software of the hot wire cnc cutting machine to lead it to the starting point of the trajectory. This program is called the introduction program. After cutting, another program is used to control the wire from the end point (usually the starting point) to the reference point. This program is called the lead-out program. The lead-in procedure and the lead-in procedure are often two straight-line procedures with the same form and opposite directions. Sometimes, the electrode wire is also guided from one reference point to another. This procedure is called a transition procedure.

For the hot wire cnc cutting machine without gap compensation, it is necessary to calculate the position of each point of each trace line. As long as a straight line program from the reference point to the starting point of the trace line is compiled, the program is introduced. Leading and transitioning are equally simple. However, in the machine with inter-belt compensation, the program module of this controller only solves the problem of scaling of graphics, but does not solve the problem of moving the electrode wire from a certain point on the round line to a certain point on the track line. Now it is not only necessary to calculate the nominal size of the drawing, but also to calculate the component X’,1″ of the distance between the trajectory of the electrode wire movement and the nominal size of the drawing on the X, Y axis, and then perform appropriate processing on the I count length. 。Set the die to be processed, in the figure, the solid line represents the size of the workpiece after processing, that is, the size given in the drawing, that is, the original contour line or the nominal size line. The dashed line represents the trajectory or equal distance of the center movement of the electrode wire Wire. Suppose the electrode wire radius is 60um, and the unilateral spark gap is 1um. It can be seen that:
X’=70um,Y”=0. Then the following processing procedures can be obtained:
1）CCC009930D8
2) C10000CCO40000E5
3)CCCO0993ODB

Here, programs 1 and 3 are the lead-in and lead-out procedures for the hot wire cnc cutting machine with clearance compensation to start processing from the reference point 0 above.

EPS hot wire cnc cutting machine adopts CAD drawing, direct the output for cutting, convenient operation, compact structure, convenient use, short auxiliary time required, and can greatly improve work efficiency.

This machine is suitable for foam factories, exterior wall insulation building materials companies, new building materials companies, machinery manufacturing, casting molds, architectural decoration and decoration, automobiles, ships, industrial design, mold manufacturing and processing, lost foam casting, advertising, foam cutting plants, foam Manufacturing plants, foam molding plants, advertising production companies, packaging plants, exhibitions, model plants, POP crafts processing and advertisement industries.
