Calculation of cutting times - saw simulator

 

Extra data for Cutting times in Review runs

 

Some distributors provide an external program to calculate the cutting times for a pattern. This is often referred to as a 'Saw simulator'. If a simulator is set up extra information is available for cutting times.

 

Management summary - Additional saw production time information

 

The extra data is at the foot of the summary.

 

Rip saw

Production time 16:11:53

Waiting for material  2:29:31

Blocked by another device  1:14:45

 

Crosscut saw

Production time 14:19:44

Waiting for material  1:14:45

Blocked by another device  0:37:22

Pattern display - saw simulation tab

 

The usual simulation display (provided by the optimising program) is replaced by a set of cycle times for the pattern. An example is shown below.

 

Pattern 1 of 3

Cycle   Time

          1     2     3     4     5  ...

 1-10    2.22  2.13  2.20  2.16  2.18

11-20    2.23  2.18  2.15  2.18  2.16

31-40    2.22  2.18  2.18  2.18  2.23

41-50    2.19  2.17  2.19  2.16  2.23

Notes

 

- Refer to the Distributor for full details of the data provided.

 

- The program calculates average cycle times based on the mean of the cycle times provided by the simulator.

 

- Saw cutting times for the pattern and the run as a whole are optional items - these are imported if available or calculated from the cycle times.

 

Pattern time =  Average cycle time * number of cycles

Run time = sum of pattern times

 

- The data provided by the saw simulator is also used to calculate the costs of cutting.
