This article documents the current sawing optimization properties as of build 15.6 and includes all changes implemented since build 15.4.
The sections below provide a reference of all the sawing properties found in the Saw tab of a Processing Station with the type “Microvellum Sawing Optimization.”
Saw Blade Width: The optimizer needs to know the width of the saw blade. Each cut removes anywhere from 3 to 7 mm of material. The optimizer must take this into account to make sure there is enough room for all the parts with the saw blade width included in the calculation.
Grippers Width: The saw has grippers that push and pull the sheets back and forth to position the sheets before each cut is made. The size of these grippers vary from saw to saw. Some grippers could get in the way of the saw blade if a narrow strip must be cut along the outside edge of the sheet. When this is the case, the optimizer must avoid placing narrow strips along the outside edge of the sheet. If the saw automatically moves the grippers to avoid collisions, then you can enter a value of zero. If not, then enter the amount your grippers overhang the panel edge.
Maximum Stack Sheet Quantity: Enter the maximum number of sheets to cut at any one time. This value will be taken into consideration until it meets the Maximum Stack Height value. “Maximum Stack Sheet Quantity” will be limited if the number of sheets stacked is thicker than the “Maximum Stack Height” value.
Maximum Stack Height: Enter the maximum height (overall thickness of stacked panels) to cut at any one time.
Premill Amount: The amount added to parts, then removed by an edgebander when banding is applied. This value is specific to what the Processing Stations “Premill Amount” setting is set to.
If set to “Use Legacy Premill,” it is the amount added to the Cut Part Size on each edge containing edgebanding.
If set to “Edgeband Thickness” or “Custom Edgeband Amount,” this value is not used and can be left at 0 (zero).
Oversize Amount: This option allows all parts to be oversized in the Saw Optimization only. The amount entered is an overall part length and part width adjustment. (Example: Entering a value of 0.5 will increase the Length of the parts by 0.5 and the width of the parts by 0.5). This is primarily used as a way to compensate for inaccurate sawing. A Single Part Toolfile will need to be customized to offset all machining by half of the oversize amount in X and Y.
Perfect Grain Second Cut Trim: When G!Perfect_Grain is turned on, Perfect Grain Blanks/Containers are sent to the saw optimizer. If you wish to have a trim amount added to the outside of these Containers, enter that amount per edge.
Re-Cut Trailing Trim: This is an oversize amount for re-squaring 3rd or higher phase cuts.
Strategy: Use the slide bar to select your desired balance between “Reduced Labor” and “Best Yield.”
Use the properties in this section to select an option reflecting your preferred method of panel cutting.
Phase 1 Always Rip Cut: The first cut will always be a rip cut. Usually with material Length or Grain.
Phase 1 Favor Rip Cut: The optimizer will try to rip cut first, but may cross-cut first if it produces a better yield.
Phase 1 Auto: The optimizer will determine how to treat phase 1 cuts based on yield or labor (See “Strategy” below).
Phase 1 Favor Cross Cut: The optimizer will try to perform a cross-cut first, but may rip cut first if it will produce a better yield.
Phase 1 Always Cross Cut: The first cut will always be a cross-cut. Usually with material Width or Grain.
Number of Phases: Select the desired complexity level. A phase is the number of times a piece of material can be cut and rotated and re-cut. The first cut is phase one. The sheet is then rotated, and another cut is made, which is phase two. This second phase-cut will sometimes produce a part or will sometimes it will have to be rotated and cut again to produce a part or group of parts. This cut is called a third phase-cut, and so on for a fourth phase-cut. The Microvellum Saw Optimizer will support from two to four phases.
Sawing Axis Type: The parameter is not used at this time. Leave the setting at “Not Specified.”
Type: Select a unit rounding method. Most will use standard.
Decimal Places: Select the number of decimal places the saw requires for accuracy.
Use the properties in this section to select an option reflecting your preferred method of panel cutting.
Place Below Layout: The program places an index number on the part in the Saw Optimization Report, then reference that index number in a list below with part details. Most Users will select this option.
Place on Placed Part: The program places part details on the part in the optimization. This method may become cluttered if many smaller parts are in a single optimization.
Use the properties in this section to select the perfect grain optimization option desired.
Group Parts for Separate Operation: The program groups Perfect Grain Parts into a single cutout to be machined as a separate operation. This single cutout is also known as a Perfect Grain Container.
Cut Parts in Initial Sheet: The program retains Perfect Grained Parts orientation and attempts to cut the perfect grain pattern along with other Non-Perfect Grained Parts within the optimization.
Connection Name: This field must remain blank unless you have requested or are required to have a customization that goes beyond the currently available setting options. You will be provided with instructions on how to utilize this field if you have had customizations added to your Saw Optimizer.
Sheet Origin: Select the origin that matches your saws origin.
Output Type: Select your Saw output type. See the list below for each type and its unique properties.
NoSawLink: No optimization saw code is produced. It only produces a saw optimization report for manual optimized cutting.
CPOUT Microvellum: Creates a standard CPOUT file which is compatible with many saw types. When this option is selected, the “CPOUT Settings” section will become visible (see properties below). You will need to edit this section, so the program matches the CPOUT Header Information. Open an existing, working CPOUT with Word Pad or Notepad. This information is usually found on the third line labeled “HDR3.” Within the line of code, you will find the P-Code and the algorithm.CPOUT Settings Section
P-Code: Select either CP10, CP20 or CP30 to match the HDR3 setting.
Algorithm: Select either Both, HV or LV to match the HDR3 setting.
Maximum Part Records in CPOUT: Enter the max number of parts to be included in a single CPOUT. Certain saws can only support a limited number of parts per CPOUT.
Create Saw OFF Records: Some saws require a CPOUT to show the waste or unused portions of the panel. This is usually for display purposes at the saw controller. If the machine requires this, turn this option on. Most will not require it.
File Number Range: Restricts the numbering range for CPOUT generated from the processing station.
CPOUT Enhanced Microvellum: Creates a CPOUT Enhanced file which is compatible with many saw types. When this option is selected, the “CPOUT Settings” section will become visible and will need to be edited to match the CPOUT Header Information as you would if you selected the CPOUT Microvellum output type. Open an existing, working CPOUT with Word Pad or Notepad. This information is usually found on the third line labeled “HDR3.” Within the line of code, you will find the P-Code and the Algorithm.
Enhanced CPOUT Settings Section: Same settings as the Standard CPOUT.
PRV: Same Settings and Controls as CPOUT files itemized above. File names will have “PRV” as the name with a progressing numeral or alphanumeric extension.
PRV Settings Section: Same settings as the Standard and Enhanced CPOUT.
