DATA:
Cost Profile
Cost profile is a collection of variables that describe how the machine, user or material affects the costs.
• Name Profile name (e.g. “plasma1 iron 0.25 inches”).
• Rapid speed Usually a constant value.
• Cutting speed Dependent on the tool, material (type and thickness) and process.
• Cut start time Time between the torch coming to the piercing point and the start of the cutting movement.
• Cut end time Time between the torch coming to the end of a cut profile and the start of the rapid movement.
• Machine hour The correct value of machine hour cost is essential to get reliable results.
• The cost of machine hour is often priced so that it includes the profit expectations that were set when the machine was purchased.
This cost is usually 60-100 $, if the machine is in active use. 60 - 100 $ is also a correct value, if you need to order some of the
work from subcontractors.
• If the machine is used only occasionally, you can choose to use just the cost of labor.
• Job preparation The time that the machine stands idle during job preparation. Job preparation time includes not only bringing the
plate to the cutting table, setting plate alignment, loading the cutting program, setting the cutting parameters but also those actions
taken after the program is cut: collecting the cut parts from the table, cutting scraps off the remnant plate, taking the remnant plate
away, etc. This time should be set so that it covers all the time between the moment the cutting table is empty and the moment
when the table is empty again - excluding the time when the machine is running a cutting program.
• Effective usage An alternative to the Job preparation. If you know that the job preparation time in your machine is usually half of
the machine time, set this to 50%.
• Consumable set The cost of a consumable set.
• Pierces per set How many piercings can be done with a single consumable set.
• Change time The time it takes to change a consumable set.
• Gas per cut hour
• Electricity per cut hour
• Other per machine hour
• Material cost How much does a square foot (or meter) of plate cost.
• Torches Quantity of torches.
• Acceleration Machine acceleration that affects the average rapid speed.
Nesting Info
This data is provided automatically by the software.
• Name Name of the nesting
• Plate area
• Plate width
• Plate length
• Collar A safety zone left by automatic nesting to the edges of a plate.
• Real usage Percentage of the parts area to the plate area.
• Nominal usage Percentage of the nominal area of the parts compared to the plate area or compared to the area of a rectangle,
which is drawn around the parts.
• Parts
• Piercings
• Nesting width
• Nesting length
• Parts area
• Cut length
• Arc seconds
• Arc seconds per piercing
• Average rapid speed This is affected by the machine acceleration. If the machine has slow acceleration and/or the average rapid
movement is short, then the machine probably never reaches the maximum rapid speed.
