Skeleton Cuts

Sheet Cutting Rules

Slice Sheet Skeleton – This option is to turn skeleton slicing on or off. Enabling this option will automatically add spaced horizontal and vertical cuts to the layout. The slice lines are added from the bottom left corner of the sheet. If a slice line passes through some parts, Cut will automatically detect this, and add multiple slice lines to slice out only the skeleton sheet left between the parts.
X spacing between vertical sheet cuts / Y spacing between horizontal sheet cuts – This is the spacing between vertical and horizontal slice lines, respectively.
Create remainder sheet – If this option is turned on, Cut will automatically create a final vertical cut that will separate the unused portion of the sheet to create a remainder sheet.
Minimum remainder sheet width – Even if the above is checked, a final cut will be added only when the width of the unused sheet created by the cut is greater than or equal to this value.
Final cut X offset – This is the distance from the rightmost extreme of part tooling to the final vertical cut that creates the remnant sheet.
Microjoint spacing on long cuts (0 = no internal micro joints) – The software can place microjoints on sheet cuts automatically. Users can specify the microjoints spacing distance parameter in settings. Microjoints will be inserted into any cut that is longer than this length. By default, this setting is set to zero which means that microjoints are not required on sheet cuts. Two kinds of microjoints are possible on sheet cuts; hard and nano. If the referred microjoint type is set to nano, then nano microjoints are created, otherwise, hard microjoints are created. Even for hard microjoints, piercing will happen on the line. There will be no approach path. However, if the LTT recommends a reduced speed approach, then a part of the line will be cut at a reduced speed after the microjoint.
Mark remainder sheet with size, material & thickness – If this option is checked, marking will be added if there are remainder sheet cut(s) on the layout. If the remainder sheet cut is removed due to some change in the settings, the marking will also be removed. Marking will always be aligned along the sheet cut, positioned at its centre. If there is not enough space to insert the text, Cut will automatically shrink the text size or change the orientation of the marking text.
Process sheet cuts after all parts – Turn on to process the slice cut at the end, after processing all parts.

Sheet Cutting Parameters

Microjoint gap at sheet edge – Set this value to the gap desired between the slice cut and sheet edge.
Microjoint gap at the part edge – Set this value to the gap desired between the slice cut and the part edge.
Pierce distance from the part edge – This is the distance of the pierce point of the slice cut from the part edge.
Measuring distance from sheet edge – If no wire joint is being created at the sheet edge, it implies that the machine must cut the sheet through till the end, however, that cannot be done with height regulation, as it will risk the machine head collapsing into the machine bed after the sheet. This parameter identifies the distance from the sheet edge where the laser head height is locked, and distance regulation is turned off. When starting a cut at the sheet edge, the machine will reach the measuring point defined by this parameter, measure the sheet height, lock its head Z position, move out of the sheet, switch the laser on and then start cutting with distance regulation off until it again reaches the same measuring point.
Overtravel after sheet edge – This is the amount by which the machine head travels beyond the sheet edge with laser on but distance regulation off.
