Cut Calculations

[Feckless]

Hi Lads,
Is there a way on the torchmate standard software for working out the total cut length, I want to use this for more accurate pricing, If I put in feedrate of 1000mm/min and multiply this by the cut time is it right or does it take into account the rapids between cuts.
How do you guys do it.
Many thanks in advance

Heres how i do it, i call the DXF file up in the TM CNC software and input a 50IPM rate, the program then calculates the cut time. based on my experience, the cut time is based on actual cut time and does not take into account the moving between cuts. thats part of the reason i use 50 as my speed. then when i cut say 14ga at 120ipm i figure i'm covered

The Cut time in the drivers software is the total cut time, including rapid travels. On the newer machines with an OK to Move signal, the time is a little short, based on the fact that the software doesn't estimate the times for the OK To Move. Most customers find it easier to price based on time of cut and consumable cost rather then inches cut.

I do it like previously said. Take the IPM and the time it takes to cut your drawing, you get inches of travel. But I'm anal, and I also figure pierces. Piercing and travel all play into how long your consumables are good for. Bob.

CNC Plasma Cost work sheet

I found the above link on another forum and find it very usefull, it's an XL worksheet and I converted it to metric for over here, Hope it's of some use to ye and I'm sure many of you have already seen it and/or use it.
That is why I was looking for total cut excluding rapids and starts

i found this same price sheet months ago. all i needed to change is the cost of material (it must be alot cheaper here in Texas). i have done many diff calcs and it seems to be a good spreadsheat. fyi you will need to know excel to make any changes
