Saw parameters to describe the features of the clamps on the program fence
These distances are used with the minimum distances of one and two finger clamping to determine whether strips can be crosscut together or not. If a set of strips cannot be adequately clamped they cannot be crosscut together. (This only applies to strips which can be cut as checkerboard strips).
On an angular saw or 3 saw system you only need to specify the clamp positions for the crosscut saw.
For a clamp to operate correctly the material must have adequate contact with the clamp. The amount of contact is calculated by determining whether a strip falls within the contact area of a clamp.
The values given for clamp and finger width are for example only.
Overall width of clamp = 65
Clamp position = 75
Finger width = 15
Distance from mid finger to mid clamp = 25 (calculated from: (65 / 2) - (15 / 2) )
Leading and trailing finger positions are:-
Finger1 1st edge: Mid point - (Clamp width / 2)
Finger1 2nd edge: Mid point - (Clamp width / 2) + Finger width
Finger2 1st edge: Mid point + (Clamp width / 2) - Finger width
Finger2 2nd edge: Mid point + (Clamp width / 2)
Finger1 1st edge: 75 - (65 / 2) = 42.5
Finger1 2nd edge: 75 - (65 / 2) + 15 = 57.5
Finger2 1st edge: 75 + (65 / 2) - 15 = 92.5
Finger2 2nd edge: 75 + (65 / 2) = 107.5
Notes
- The program works out the contact areas for each finger of each clamp and these areas are then used to assess whether a particular strip can be adequately clamped or not.
- Define up to 18 clamp positions, using the clamp position parameters
- It is always assumed that a single strip can be cut on its own regardless of the width of the strip.
- If working in inches enter the clamp positions in decimal inches.
- If all clamp positions are set to zero the program assumes clamping is infinite.
- Also set the clamp positions to 0 if there are more than 18 clamps. In these situations the program determines which strips are cut together from the saw parameter - Max width for crosscutting multiple strips
