Toolpath optimization variant attributes

OLP_TP_Evaluation_21

The Variation space defines what modifications can be made to the toolpath elements to search for the optimal solution, i.e. minimal costs. It shows all variables that can be included in the optimization process, their range within they can be varied and the distribution step or discretization within that range.

The variables here might be specific for a technology or a certain technology setup in combination with an OEM brand controller and robot or machine. In other words; the exact content of the container might look different for each case.

The most common variables are:

Parameter	Description	Optimization options	Remark
Tangent rotation	Varies the toolpath position while rotating it around its tangent direction.	Step size Rotation value in each iteration step.	Switch to include it in the optimization process.
Bi-tangent rotation	Varies the toolpath position while rotating it around its bi-tangent direction.	Step size Rotation value in each iteration step.	Switch to include it in the optimization process.
Singularity orientation	Evaluates singularity situations of the robot or machine. In case of a robot scenario, the singularity orientation means the rotation of the toolpath position around its normal axis.	Step size Rotation value in each iteration step. Deviation cone Axis with values within the specified cone angle are being optimized.	Switch to include it in the optimization process.
Normal rotation (arc welding technology)	Varies the toolpath position while rotating it around its normal direction.	Step size Rotation value in each iteration step.	Switch to include it in the optimization process.

The Boundary conditions section includes additional parameters that can be introduced to limit the amount of variations. Where normally the tangent and bi-tangent rotation of the toolpath position can vary between -180 and +180 degrees, cause these parameters extra conditions to allow the tangent and bi-tangent axis to rotate only within the range and as long as the boundary condition is still met.

Parameter	Description	Optimization options	Remark
Max. process angle deviation	The maximum allowed process angle deviation from the reference direction.		An optimization result is accepted when the process angle is smaller or equal to this value. This condition can only be applied when its corresponding criteria Process angle deviation has been disabled from the quality evaluation.
Max. work angle deviation (arc welding technology)	The maximum allowed work angle deviation from the reference direction.		It replaces the process angle deviation criteria. Only applicable when 6-axis robots are being used.
Max. travel angle deviation (arc welding technology)	The maximum allowed travel angle deviation from the reference direction.		It replaces the process angle deviation criteria. Only applicable when 6-axis robots are being used.
Max. tool angle deviation (arc welding technology)	The maximum allowed tool angle deviation from the reference direction.		It replaces the process angle deviation criteria. Only applicable when 6-axis robots are being used.
