Definitions

  • FIGS. 1 and 2 illustrate a fluid stream 10 exiting an orifice 12 of a nozzle 14 to cut a workpiece 16 .
  • the nozzle 14 and hence the fluid stream 10 are moved along a desired path 15 relative to the workpiece 16 .
  • the nozzle 14 moves in and out of the page, while in FIG. 2 the nozzle 14 moves in the direction indicated by arrow 15 .
  • the resulting cut 20 made by the fluid stream 10 has a width on a top surface 22 (facing the nozzle 14 ) that differs in width from the bottom surface 24 (facing away from the nozzle 14 ).
  • the resulting taper 28 due to the difference in widths is referred to as the “Kerf angle” 30 .
  • the Kerf angle 30 is the angle the cut face 32 is out of parallel from the fluid stream axis (the stream is often not normal to the material surface by design).
  • the taper 28 is a function of material thickness, but also is a function of cutting speed or movement of the nozzle 14 .
  • the taper 28 becomes less as cutting speed slows, and then as cutting speed further slows beyond a point, the taper 28 reverses from that illustrated in FIG. 1 becoming narrower toward the surface 22 .
  • Compensation for the taper 28 typically includes tilting the nozzle 14 relative to the workpiece 16 about the axis of motion of the nozzle 14 .
  • a “lag” is present due again to the thickness of the material and movement of the nozzle 14 .
  • a deflection distance 32 is defined as the difference in length between the point where the fluid stream 10 impinges the top surface 22 and where the stream 10 exits the bottom surface 24
  • a “Kerf lag” can be defined as an angle 34 using a straight line 36 formed between these points.
  • the Kerf lag 34 does not affect cutting accuracy when cutting a straight line since the exiting portion of the fluid stream 10 follows the impact point.
  • the deflection of the fluid stream 10 can cause cutting errors as it flares to the outside of a corner leaving behind or cutting undesirable deflection tapers.
  • the finish of even straight line cuts is affected by the speed of the nozzle 14 .
  • the lag 34 may be reduced by slowing the motion of the nozzle 14 across the workpiece 16 .
  • tilting of the nozzle 14 in this case, about an axis transverse to the direction of motion can also provide some compensation for the lag 34 .
  • a system and method for positioning a fluid stream for cutting a double contour workpiece includes a compensation module configured to receive information regarding a contour path in at least five degrees of freedom for cutting the double contour workpiece and a velocity of movement of the fluid stream during cutting and configured to provide as an output a modified contour path of said at least five degrees of freedom based on Kerf compensation errors.
  • a motion controller is adapted to receive the modified contour path of said at least five degrees of freedom and the velocity and is configured to provide control signals.
  • a positioner is configured to receive the control signals and position a fluid stream adjacent the workpiece accordingly.
  • FIG. 1 is schematic illustration of a taper present in fluid stream cutting of the prior art.
  • FIG. 2 is schematic illustration of fluid stream lag present in fluid stream cutting of the prior art.
  • FIG. 3 is a flow diagram illustrating exemplary operation of a fluid stream cutting system.
  • FIG. 4 is a pictorial representation of a cutting path provided with compensation.
  • FIGS. 5A, 5B and 5 C are pictorial representation of a polynomial based compensation for an exemplary material.
  • FIG. 6 is an exemplary schematic illustration of a taper present in fluid stream cutting of the present invention.
  • FIG. 7 is an exemplary schematic illustration of fluid stream lag present in fluid stream cutting of the present invention.
  • FIG. 3 is a block/flow diagram illustrating exemplary operation of a fluid stream cutting system 100 .
  • material is cut using a fluid stream cutting apparatus (also commonly referred to as a water jet system although other types of “fluids”, which is defined herein as including liquids, plasma, particles, gases or combinations thereof, can be used) 102 , which are well known and therefore is shown schematically.
  • apparatus 102 includes nozzle 14 ′.
  • prime numbers are used to indicated similar concepts above; however, the workpiece to be cut and the cutting process itself is different in that a complex workpiece that can have double contours and/or varying thickness is cut.
  • the cutting nozzle 14 ′ of cutting apparatus 102 is moved relative to the material to be cut or workpiece by a multi-axis positioner (e.g. 5 or 6 axis control) 104 .
  • a multi-axis positioner e.g. 5 or 6 axis control
  • positioners are well known and need not be discussed in detail for purposes of understanding the concepts herein described.
  • the typical technique for fluid stream cutting is to mount the workpiece (sometimes also referred to as the “material being cut”) in a suitable jig.
  • the fluid stream or fluid-jet is typically directed onto the workpiece to accomplish the desired cutting to produce a target piece having a shape and is generally under computer or robotic control.
  • the cutting power is typically generated by means of a high-pressure pump connected to the cutting head through high-pressure tubing, hose, piping, accumulators, and filters. It is not necessary to keep the workpiece stationary and to manipulate the fluid-jet cutting tool.
  • the workpiece can be manipulated under a stationary cutting jet, or both the fluid-jet and the workpiece can be manipulated to facilitate cutting.
  • cutting parameters such as but not limited to a cutting velocity or speed of the nozzle, its cutting path including orientation of the nozzle are determined in order to generate the desired workpiece with requisite compensation taking into account characteristics of the cutting process.
  • workpiece specifications are embodied in a Computer-Aided Design (“CAD”) program or model 106 .
  • CAD models are well known and can be developed for the desired workpiece using a computer workstation (not shown) that is separate from or part of system 100 .
  • the CAD model 106 is provided to a Computer-Aided Machining (CAM) system 108 that is used to determine initial machining parameters in order to generate the desired the workpiece including but not limited to the cutting path (i.e. motion profile), which can then be “post processed,” if necessary, into a format for a specific positioner or cutting apparatus.
  • CAM Computer-Aided Machining
  • a cutting path 200 for a portion of a desired workpiece can be described in terms of a sequence of datasets 202 comprising coordinates in five degrees of freedom (X,Y,Z,C,B), e.g., three translations (X,Y,Z) and two angles of tilt or surface normal vectors (B,C) in a reference coordinate system 202 .
  • X,Y,Z,C degrees of freedom
  • B,C surface normal vectors
  • modules illustrated in FIG. 3 and discussed below are presented for purposes of understanding and should not be considered limiting in that additional modules may be used to perform some of the functions of the modules herein described. Likewise, functions can be divided or combined in other ways between the modules.
  • the modules can be implemented with digital and/or analog computational devices such as a computer.
  • a compensation module 113 illustrated generally by dashed lines is illustrated for purposes of understanding as decision block 112 , path compensation assembly 140 and/or Kerf compensation component 160 and as described below provides a modified contour cutting path in at least 5 degrees of freedom and velocity.
  • a velocity of the nozzle as a function of the cutting path can also be provided by CAM system 108 to form a “motion profile”, which is represented in FIG. 3 at 110 .
  • input 110 can include velocity indications or criteria (e.g. maximum velocity) Nevertheless, any initial velocity, if given, may not be optimal given the cutting conditions such as but not limited to the shape of the desired workpiece. Accordingly, the velocity may be adjusted as represented by decision block 112 .
  • a model steady state velocity input 114 to block 112 is provided from a processing component 116 using known cutting models such as that described by J. Zeng in “Mechanisms of Brittle Material Erosion Associated With High Pressure Abrasive Waterjet Processing,” Doctoral Dissertation, University of Rhode Island, guitarist, R.I., 1992.
  • component 116 receives as input the type of material being cut 118 , a qualitative measure of the “quality” of the desired cut 120 and the thickness of the material 122 , and other parameters as indicated above in the equation above to determine the model steady state velocity 114 .
  • a further velocity effect input 126 (also referred to as “transient look-ahead velocity effect”) provided herein allows the resulting velocity 128 from block 112 to be further modified based on constraints imposed by the physical movements of the nozzle.
  • the velocity effect input 126 originates from a motion controller 148 for positioner 104 , which can include a module 149 that looks for conditions of needed velocity reductions. For example, and without limitation, it may be necessary to depart from the model steady state velocity 114 when approaching a sharp corner to be cut in the workpiece, where for instance, the velocity of the nozzle must be slowed down prior to reaching the actual corner to be cut. In yet another situation, velocity reduction would be necessary if the operator operates a “stop” switch during cutting.
  • motion modules 151 can also affect velocity such as motion of the nozzle to or away from the top surface 22 as monitored, for example, by a suitable sensor.
  • transient look-ahead velocity effect input 126 is based on any motion to be performed by the cutting nozzle that causes it to depart from velocity 114 .
  • Path compensation assembly 140 is provided to address some of these errors. Path compensation assembly 140 is based on the use of polynomial equations or models 143 for each of the Kerf errors, Kerf width (Kw), Kerf angle (Ka) and Kerf lag (Kl) using empirical data 142 from actual cuts for various materials and material characterization data of the materials 144 along with inputs pertaining to the actual material being used, its thickness and the desired quality and the resulting velocity 128 from block 112 .
  • Kerf error compensation for Kerf width (Kw), Kerf angle (Ka) and Kerf lag (Kl) is provided.
  • prior techniques did not include a dynamic aspect for such compensation, which is provided by the feedback of velocity input 126 from a motion controller 148 for positioner 104 .
  • such compensation either static (without input 126 ) or dynamic (with input 126 ), is provided when cutting a workpiece requiring at least 5 degrees of freedom, that is, cutting a workpiece that can have a double contour, which is a significantly different and more complex operating environment than cutting a workpiece in a plane, yet allowing the nozzle to provide at least two degrees of tilt for Kerf compensation.
  • path compensation assembly 140 can calculate, in a dynamic sense, the compensation required for the Kerf based errors.
  • Kerf based errors are dynamically compensated due to the over-eroding cutting nature of fluid stream cutting as velocity of the nozzle reduces.
  • thickness values can be provided from a cross-section analyzer 154 based on the known geometry of the material/workpiece.
  • a cross-section analyzer sensor 156 can provide a signal related to thickness as actually measured during cutting. Examples of suitable sensors include but are not limited to mechanical, optical, electric ultrasonic based sensors. This feature of cutting material to desired shape as well as quality specifications for a constantly varying thickness is particularly useful in complex, arbitrary double contour workpieces such as airplane wing components that commonly vary in thickness.
  • FIGS. 5A-5C are representations of polynomial based Kerf error compensation for an exemplary material.
  • a Kerf compensation component 160 accepts the Kerf width, Kerf angle, Kerf lag based errors calculated from path compensation assembly 140 as well as the velocity and the contour path datasets (X,Y,Z,C,B) for five dimensional control cutting and (X,Y,Z,C,B,A) for six dimensions, if desired, from CAM system 108 .
  • the Kerf compensation component 160 applies the Kerf compensation errors calculated by path compensation assembly 140 to the specific location of the actual contour being cut. In other words, the Kerf compensation error information provided by path compensation assembly 140 by itself is not enough to move the nozzle 14 ′.
  • the Kerf compensation component 160 includes an instantaneous tool path vector calculator 162 that computes an instantaneous motion path vector from the part program point in the neighborhood of the current position so as to determine which way compensation needs to be provided in view of what side at any given position is part of the desired workpiece versus the waste, salvage or drop material.
  • the 5 or 6 axes part program and the computed motion vector are then used to compute the instantaneous 5D or 6D motion command or tool frame by component 166 .
  • component 166 In a dynamic mode, other linear, angular, and/or velocity effects determined by the motion planner are incorporated simultaneously.
  • the total compensation consisting of Kerf width, Kerf angle, Kerf lag, and motion planner effects, are applied to the command frame by component 170 .
  • the resultant modified path and velocity can be stored at 168 and, if desired, a summary report containing relevant information pertaining to the cutting process can also be generated and stored also at 168 such as how long the workpiece took to be cut. It is noteworthy to realize that this report can be based on simulated cutting because given the known cutting path and the dynamic velocity changes, actual overall cutting time can then be estimated, or other problems can be detected prior to actual cutting. However, in addition, or in the alternative, in a real-time cutting mode, the modified path and velocity data is submitted, for execution by the motion controller 148 .
  • Path 200 is defined relative to some reference or command coordinate system 204 ; however, in view that at least five degrees of motion control define the cutting path 200 , two degrees of tilt (surface normal vectors) are also provided. Accordingly, as indicated above, defined points 202 on the cutting path are represented (by way of example with five degrees of control) as (X,Y,Z,C,B).
  • the adjacent points before and after the current point under consideration are examined in order to determine a instantaneous motion vector 206 at the current point (point 202 A by way of example).
  • the instantaneous motion vector 206 is then used in order to ascertain the cross-section 208 of the cut being made ( FIG. 1 ), which is orthogonal to the instantaneous motion vector 206 , as well as the cross-section along the cut ( FIG. 2 ), which is along the instantaneous motion vector 206 .
  • the Kerf corrections are made relative to the instantaneous coordinate frame at the current position 202 A and translated back into the reference coordinate system 204 as (X′,Y′,Z′,B′,C′) where no velocity feedback effect 126 is provided, or as (X′′,Y′′,Z′′,B′′,C′′) when velocity feedback effect 126 is present.
  • Kerf compensation component 160 can also factor in other process variables monitored by a process monitoring module 182 such as but not limited to the changing diameter of the orifice as the nozzle wears (due for example to “Jet-on” time), abrasive rate, pressure, etc. This is illustrated by signal line 180 , the input of which can also be applied to path compensation assembly 140 .
  • a module 184 can be provided to signal when the nozzle requires replacement or when other process variables require attention.
  • some aspects herein described include Kerf compensation in a true five dimensional or more cutting environment, the compensation of which can further include dynamic compensation based on constraints or desired motion of the nozzle for other reasons besides cut quality, as well as workpieces having a constantly vary thickness.
  • the compensation herein provided is not limited to a static cutting path/orientation based on post processing of the initial cutting path (relative to CAM system 108 ) or compensation provided during dynamic motion control (during actual cutting), but rather a compensation mechanism that can be used in each one separately, or a combination of the foregoing situations.
