Draw Tool Path Mastercam Zigzag

3D Nonintersecting

Comparable is a versatile finishing strategy which is usually applied for shallow or relatively flat regions in your geometry. As the name implies, the Parallel strategy rasters on the surface in parallel lines, either backward and forward (zig-zag) or in unmatched direction only. This means that when looking at the part from straight above, the toolpath wish look like a set of parallel lines in a shave but the tool course e'er follows the meridian of the geometry.

Full Control over Every last Parameters

You arse control exactly in which realm of your geometry the Parallel scheme should be practical by selecting a range of slope angles. Furthermore, you can define a machining angle, which means that the toolpath is turned outside from the x-axis. This is frequently cooked to guarantee maximum preciseness by exploitation all three machining directions simultaneously. Twin supports pillow machining such that you only political machine regions which were not machined aside preceding trading operations. You can freely configure the lead-in and lead-out moves of the operation. HSM Performance Throng generates top arcs with best suaveness to minimize the tool wear. In addition, some the ramping and linking moves are freely configurable to match your tool, machine and part.

In the large area, the tool is selected, or a New tool force out beryllium created from the right suction stop menu. The fields below are automatically updated from the tool selected above. The tool drawing to the right is updated for each one sentence a theatre of operations is exited, to reflect the changed value. The the right way dawn menu is too used to access the HSM tool library, described below.

The flute length doesn't have an effect on the shape of the tender paths unless a taper fish is practical. Tapered tools bestow the shape of a cone of the tending taper angle from the consolidation axis. The backside of the (truncated) cone is tangential to the shape at the tip, and the top is at the champagne flute length above the tip. For tapered tools, the tool definition is straightforward for globe nosed and flat tire bottomed tips, just for bull sharp-nosed tips the standard convention is more than complicated: the shaft diameter refers to the diameter of the bottom of the conical surface and not the diameter of the virtual toroidal shape that would be within the tapered shape.

In the section Shaft and holder you can define holder and shaft collision checks and how the toolpath should respond to detected collisions. In particular, this is where you can delimitate to tilt the tool in suit of a collision, effectively creating a 5-Axis toolpath.

Note that these collision checks require additional calculation time when the toolpath is generated, just ensures that the shaft and holder do not collide with the voice if used.

The following parameters can be plant to operate the hit sensing (note that not entirely parameters are available for all strategies):

Hit detection policy

The dropdown fare lets you select how HSM Performance Coterie should react to a detected holder hit. The following options are available (depending along the designated scheme):

Ignore

With the option Ignore, collisions between the shoulder, shank, holder and the work art object are ignored.

Trim

When the trimming selection is selected, toolpath will be trimmed away in areas of holder collisions.

Tilt to avoid collision

With this option, the tool is tilted far sufficient so that information technology can spend a penny the cut without having the bearer collide with the part. Only toolpath with a ball nose John Stuart Mill crapper glucinium canted. This mode is supported for finishing strategies.

Pull away

In the pull inaccurate modality, the kernel avoids shoulder/stem/bearer collisions with the break u by awheel the joyride inaccurate from the surface. It is important to bill that some stock might not be machined in this case and the toolpath may contain some air cuts. This mode is selfsame useful when the "undercut" option is enabled for 3D Contour or Horizontal atomic number 3 IT helps to invalidate trimming and ensures that as much of the part as possible is machined.

Note: The Move back option is non supported in undercut modal value.

Detect distance

With the option detect lenght, HSM Carrying into action Pack checks toolpath and suggests a flute length to the user for which any bearer collisions are avoided.

A warning such as the followers will be provided to suggest a tool:

"Dissuasive: Instrument flute must be increased away 53.04 to ward of holder gouge."

Fail on collision

With the option miscarry along collision, the toolpath generation fails just in case the software detects a holder collision.

The undermentioned is an example mistake which is provided to help the user in removing the gouge:

"Error: Bearer Gouge detected at point (37.7439,-57.5288,0), tool axis: (0,0,1), linking path #102"

4-axis of rotation tilt

Allows the user to force 5-axis of rotation tilt single along the toolpath.

Bearer clearance

The Holder clearance defines the guard length betwixt the holder and the stock. If the bearer gets closer to the set off (operating theater stock) than this outstrip, IT will be treated every bit a collision.

The field Absolute clearance tiptop can be enabled to define an absolute Z treasure instead.

Retract height

The Retract height defines the peak to which the tool retracts between cutting passes. The linking moves at this superlative are carried out at rapid speed. The summit is congeneric to the top of the surface to be machined.

The field Absolute retract elevation can be enabled to define an absolute Z value instead.

Safe distance

The Innocuous distance defines the minimum distance between the instrument and the part surfaces during shortest route retract moves. This outstrip is measured later on the stock to leave has been applied, so if a negative stock to pass on is used, special care should be taken that the safe distance is mammoth enough to ensure that no collisions occur.

Retraction policy

The Retraction policy determines how moves between stabbing passes are through with. Shortest itinerary is the shortest possible path (which often includes moves in all three axes), Minimum retraction is uncurved up to the worst height where the tool will be clear of the part (by safe Z distance), and Full recantation is to the clearance plane.

Allow fast retract

By sanctionative Allow rapid retract, vertical retract moves will represent carried out at rapid speed. If this is not enabled, retracts will be carried out at the lead-extinct feedrate.

Explicit lead out

By enabling Explicit lead out you dismiss define the lead out parameters severally from the lead in parameters. If non enabled, the lead extinct parameters will be identical to the trail in parameters.

Perpendicular lead

Sweep

Drag defines the slam fish between the linear segment component of the lead-in/out movement and the toolpath.

End run (hin out)

Sweep (lead stunned) defines the sweep angle 'tween the linear section component of the lead out movement and the toolpath. You pauperization to enable Hard-core lead unsuccessful in order to specialise a divided lead impossible sweep angle. Otherwise, the same lean against will cost used for lead-in and lead-out.

Linear lead distance

Elongate booster cable space defines the length of the linear segment component of the chair-in/out movement.

Linear lead out outdistance

Analog go out distance defines the duration of the linear segment component of the lead/out move. You need to enable Expressed pencil lead out in order to set a separate linear lead out distance. Otherwise, the same distance testament be utilised for lead-in and lead-out.

Keep down distance

The Keep down distance defines a distance beneath which retracts are avoided. This means that lead-in and lead-out moves are still generated below this length, but the tool is only upraised up slenderly.

Max passage distance

Economic consumption the parametric quantity Max transition distance to define a maximum allowed distance for transitions between cutting passes. If the distance between deuce passes is greater than the Max passage aloofness, the tool retracts or is lifted up and a lead-unsuccessful and lead-in are generated.

Contact ramp insurance policy

From the dropdown menu contact ramp insurance policy you can select the method acting away which ramps should equal carried out 'tween different cutting passes. The in stock options are:

Straight delineate: This defines that the transitions are simple straight lines betwixt two cutting passes.

Curve: In this mode, the transitions are smooth curves which are tangential to the film editing passes at both ends of the passage.

Disabled: This disables changeover moves.

Basic

Tolerance

Permissiveness defines the maximum value the toolpath is allowed to deviate from the surface of the input geometry. A small permissiveness value yields more precise toolpaths at the disbursement of longer computation times.

Stepover

The stepover is the distance 'tween two cutting passes. The stepover must always glucinium less than or equal to the tool around diameter since otherwise the toolpath might allow for stand-ups between cutting passes.

Gillyflower to parting

Stepdown

Stepdown is accustomed calculate offset value betwixt cuts if several steps are used.

Number of stairs

The routine of steps used in toolpath if material should live removed in different cuts.

Machining angle

With the machining angle the generated toolpath can be rotated in the XY-plane. Usually this is desirable to ensure that the tool does not raster along one and only of the principle axes of the machine.

Automatic angle

Mechanical angle allows software to compute optimal machining for each cutting sphere along the part.

Note : Machining angle is disabled if this option is used.

Observe : Perpendicular fill International Relations and Security Network't tolerate if this mode is ill-used.

Allow tenderloin

Use the alternative allow undercut to perform undercuts, i.e. the tool around is allowed to cut under just about unexhausted material. This is supported for lollipop creature and ball tool with enabled cant.

Optimize cut order

Optimise cut order allows software mechanically set the best ordering. Other than everything is linked in swordlike sequent govern.

Accommodate arcs

Fit arcs allows vertical arcs in cutting toopaths.

Perpendicular fill

Perpendicular fill allows software to generate newspaper clipping toolpath which is English-Gothic to provided machining angle in both areas to put up better machining quality.

Direction

Charge

From the dropdown menu counseling you can select in which directions the strategy is allowed to slashed. You can choose betwixt one and only way, other way, both ways, down milling and up milling.

One way: The option one way defines that all cuts wish personify taken in the Same direction. The puppet will retract and chop-chop move to the beginning of the next diluted.

Other way: The alternative other way defines that all cuts will be assumed in the equivalent focusing, but opposite of peerless way. The tool will retract and quickly move to the commencement of the next cut.

Both slipway: If some ways is hand-picked the cuts will be carried call at both directions along the surface. The passes are linked with smooth linking arcs (if curve transitions are treated). both ways is the to the highest degree common selection and usually results in the shortest toolpath.

Knock down milling: With the option down milling the tool will always move down hill along the geometry.

Up milling: When up milling is selected the creature only moves up hill along the geometry.

Cutting depth

Confine depth

Activate confine depth to specify depth limits for the toolpath, useful for machining deep pockets, where the upper areas are to be machined with a shorter puppet, and the lower areas with a longer tool.

Minimum depth

The minimum depth is the height at which the cuts begin.

Utmost depth

The maximum depth is the final cutting depth of the operation.

Rising / Descending mill

Shallow angle

Perpendicular

Machine steep areas

Trigger machine exorbitant areas to add additional cuts in steep regions of the geometry by dynamically reducing the stepover in steep regions.

Minimum stepover

The minimum stepover is the smallest possible horizontal spacing betwixt two cuts. When machine heavy areas is used, the minimum stepover ensures that HSM Performance Pack does not add extremely narrow cuts in almost vertical regions of the geometry. HSM Functioning Pack tries to ensure a stepdown smaller than the maximum stepdown, simply only as long as the stepover is bigger than the nominal stepover.

Maximum stepdown

The maximum stepdown is the level bes vertical spacing between deuce cuts. This criterion is used to tot up additive cuts when machine steep areas is active: HSM Performance Pack reduces the stepover to control that the stepdown does not outgo the utmost stepdown. Note that the stepover leave never be reduced to less than the minimum stepover.

Trim absorb passes

Activate trim steep passes to trim additive toolpath that was created in shallow areas payable to the option car steep areas. For volumed parts where at that place are shallow and steep walls in the same cut, steep sphere machining can lead to many excessive cuts in neritic areas of the part. Activating trim steep passes adds additional cuts in soak up areas, whereas cuts in shallow areas are trimmed away.

Ignore distance

Victimized when trim steep passes is enabled. Allows to skip passes with length to a lesser degree provided value.

Merge distance

Used when trim immoderate passes is enabled. Allows to merge passes if distance between them is less than provided value.

Rest material source

Disabled: Defines that the current operation is not a rest machining operation. Choose this to carry out a regular operation.

Residue material operation: The rest physical is calculated as the material left in arrears by one or more earlier operations. This is the most accurate method to use, Eastern Samoa it industrial plant from where the tool actually went in the earliest operation, taking into account the space needed for lead in/out motions, arsenic well as some other limitations of the earlier operations. This is also the only way to take many than unmatched operation into account. Due to the increased precision, this method may take yearner than other options to calculate. The operations which should beryllium included in the rest material calculation are selected below.

Rest reincarnate STL file: The remaining material is calculated from a STL file, shaping a pre-roughed or form part, for example. The STL file must be specified below.

Sleep physical tool: Uses a theoretical puppet to calculate the rest domain, left past this tool, and uses it as basis for the relief material calculation. The theoretical instrument is specified by its diameter and corner radius.
