Mastercam CNC programming experience sharing, it is recommended to collect the Mastercam dynamic toolpath.
Machining from the outer edge of the material to reduce the number of spiral feeds. Full-edge cutting enables the first tool rate to reduce the first rate to protect the tool. At this time, the cutting rate can be increased.
If there is a through hole during processing, punch the through hole first, and select this as a blank area when the toolpaths are connected in series. At this time, the cutting method is the best
Enter the series, the selected line tool path will be extended to this line (need to select in the series mode)
One
1. The area milling toolpath overlaps and the offset along the toolpath
XY step is less than %50
Fillet setting reference
Maximum radius tool diameter×%10-15
Contour tolerance tool diameter×%3-5
Compensation tolerance tool diameter×%8-10
Island depth
2. The method to solve the full-edge cutting, the cycloid mode adjustment (the feed rate cutting step is adjusted to a larger point)
3. The total difference of arc filtering tolerance = reserved amount (previous operating margin) ×% 20 (can be larger when rough cutting)
-
The blank setting is that when the material is processed and the residual material is cleaned, only the corners and the rounded corners need to be cleaned. Other finishing can be solved (adjust the range of the residual material to filter out the places that do not want to operate). Generally, the residual material is processed by the shape milling residual material:
-
If the high-speed tool path is not in a closed range, the knife will enter from the unclosed area, and the air cutting range is empty. The knife will automatically enter from the empty.
6. The avoidance range can be a line or a surface (the avoidance range is similar to the interference surface)
7. The difference between area milling and dynamic milling is the automatic control path of dynamic cutting. The path of the tool is automatically calculated, which can avoid the full-edge cutting area. The cutting area can be changed according to the range. There is no dynamic range. Play automatic calculation.
8. The arc becomes a straight line and the filter tolerance is too large
9. Residual material blank processing is residual material processing
Welding toolpath
1. Where there is an arc in the middle of the openings on both sides, use the inside-out method to fill in the evidence.
three
Dynamic milling
1. Deal with small rounded corners, the minimum turning radius is not less than %10
2. The cutting tool should not exceed 12mm.
3. Control the range of motion of the area knife
4. The additional groove width increases the opening of the sharp corner toolpath to achieve the effect of rounding the sharp corner
5. The rough setting includes material cleaning
four
Dynamic shape
1. In addition to the residual material (shape blank), the reserved amount formed by the radius of the tool refers to the radius of the last operation tool
①Minimum tool path radius refers to the radius of the corner when the tool path is rounded, (the minimum arc radius related to the place where the residual material is cleaned)
②The thickness of the blank refers to the difference between the thickness of the current material and the thickness of the required material (that is, the reserved amount)
2. When wear is enabled, it must be set to advance and retreat, otherwise the machine will alarm
