Details explaining the saw simulation report
Book height
The book height shows the lesser of the maximum book height (Cutting height/material thickness) or the total number of boards. For example, if the maximum book height is '5' but the total number of boards is '4' it shows '4'. If total number of boards is greater than '5' then (in this example) it shows '5'.
Simulation codes
The two letter codes used are:-
BT - bundle loading
TI - transfer from rip to int. table
ST - setup time
HC- head cutting
PS - pre-stacking
RT - return transfer of main to rip
FD - feeding
RH - ripping head
PH - pos. for head cut saw
RM - ripping main
PR - pos. for rip saw
TS - turning strips
TT - turn board
DB - drawback strips or board
OF - outfeed after last rip
XT - cross transfer
OH - outfeed from head
XH - crosscutting head
XM - crosscutting main
DS - destacking
ZC - recut
Where the code is followed by a number this indicates the number of the set of strips or parts. e.g.: RM1 - rip main first set of strips for ripping. XM2 - crosscut second set of strips.
Angular saw display
For Angular and 3 saw systems the cycle is determined as the longest stable time between two equivalent points, typically between the start of pre-stacking in one cycle and the start of pre-stacking in the next cycle. The time charts show a separate line for each part of the saw that can operate independently, for example, the pre-stacking operations, rip saw, and crosscut saw. The time chart also shows operations around this cycle so that it can be seen in context.
The time shown is the continuous cycle time (excluding the run in time) and total time per pattern is just the continuous cycle time multiplied by the number of cycles.
The first few cycles in a run are not usually typical, especially for an angular saw, because the saw is idle when you start; the same applies to the cycles at the end.
Cutting times
Cutting times are the estimated times for cutting a pattern or a set of patterns. The cutting time is an important factor in the overall cost of a job and it depends upon a wide variety of features. The main elements are:-
- Complexity of pattern (number of cuts, re-cuts, head-cuts)
- Saw model (single, angular system, use of turntable)
- Operation of the saw (transfer speed, saw blade speed, etc)
Use the saw parameters to define the saw model, physical features of the saw, and saw speeds and times.
For accurate cutting times make sure the saw model is correct and that all the relevant saw parameters are set
Check the saw times with the supplier as the timing of a saw operation can be quite complex, especially for angular or larger systems, and varies with the mix and order in which patterns are processed.
Printing
The Review runs parameter: Simulation scale controls the simulation minutes per page width.
