3What’s different with HST Toolpaths New Parameter TabsOperations can now be copied with current settings and then change toolpath type (Core Roughing to a Waterline toolpath)
4What’s different with HST Toolpaths New Parameter TabsWhen changing toolpath type any parameters that can be kept from the copied operation are kept.
5What’s different with HST Toolpaths Quick View SettingsQuick View Setting keep info in sight through all parameter tabs so there’s no need to change tabs to get information.
6Toolpaths Area Clearance Area Clearance: Is a roughing toolpath for clearing out material in cavities, cutting from inside out.
7Toolpaths Area Clearance Notice that the toolpath starts from the inside out
8Toolpaths Core Roughing Core Roughing: Is a roughing toolpath for clearing out material that changes strategies from outside in for bosses and inside out for cavities.
9Toolpaths Core Roughing Notice the tool starts on the inside and works its way out for the cavity
10Toolpaths Core Roughing RapidCut directionNotice the tool starts on the outside and works its way in on bosses.

12Cut ParametersNote: The cut parameters will change based on the toolpath type. When possible the same settings will be brought into the new toolpath type.
13Cut Parameters Turn on the “Add cuts” option Stepdown – Determines the Z spacing between adjacent cutting passesAdd cuts- Activates the adaptive stepdown feature, which add cuts at the shallow areas of the profile so that the toolpath does not have excessively large horizontal spacing between cutting passesMin stepdown – Specifies the minimum stepdown value when Add cuts is activated. Passes will be no less than this distance from each other – in the z axis
14Cut ParametersMax profile stepover – Determines the maximum change in the surface profiles for two adjacent cutting passes. This represents the maximum value of the shortest horizontal distance between adjacent points on the two profiles.Max profile stepover – is the thickness of the scallop. If the thickness exceeds the .250 setting then a z cut is added to bring the thickness under the .250 setting.
17Cut Parameters Turn on the “Smoothing” option Smoothing – Replaces sharp corners with an arc for faster and smoother transitions in the tool direction.
18Cut ParametersMax Radius – Enter the radius of the largest arc that you will allow Mastercam to insert to replace the corner. Larger arcs will result in a smoother toolpath but with greater deviation from the originally programmed toolpathProfile Tolerance – The maximum distance that the outermost profile of the smoothed toolpath that will deviate from the original toolpathOffset tolerance – This is the same measurement as the profile tolerance but is applied to all of the profiles except the outermost one. This lets you maintain different tolerances for the subsequent profiles.
19Cut ParametersPossible to leave different amounts of stock for floor and wall surfaces.Note: Can’t leave less stock on the walls than the floor
24Rest MaterialAll previous operations - Calculates the remaining stock using all operations in the Toolpath Manager. This method determines the areas of stock where the tool did not go.One other operation - Calculates the remaining stock using all operations in the Toolpath Manager. This method determines the areas of stock where the tool did not go.Roughing tool - Calculates the remaining stock based on the diameter and corner radius of a tool.Cad file – Uses an STL file to calculate where the tool can remove material
25Rest MaterialLists the current operations in the operation manager
26Rest MaterialStock resolution - Use a smaller value to tighten up the stock model and create a smoother restmill toolpath. Use a larger value to loosen the stock model and create a faster but rougher restmill toolpath.
27Rest Material Adjustments to remaining stock Use remaining stock as computed – No adjustment to the stock modelAdjust remaining stock to ignore small cusps – Use this setting to set the adjustment distance to reduce the stock model, this setting will find less material to machineAdjust remaining stock to mill small cusps – Use this setting to set the adjustment distance to increase the stock model, this setting will find more material to machine
28Rest Material Adjustments to remaining stock Adjustment distance - Enter a value to expand or reduce the calculated stock model
29Rest Material Roughing tool is a theoretical calculation. Note: With the “Skip pocket” setting its possible to have the tool plunge into material with the “Roughing Tool” setting
30Rest MaterialAn STL file can be used to calculate remaining stock. Verifying a toolpath and then saving the stock as an STL may give a more accurate results.

84Defined Slope Angle for all High Speed Toolpaths Steep / ShallowDefined Slope Angle for all High Speed ToolpathsAngle options is used to only create cutting passes on those areas of the part that fall in the angle setting.
85Steep / Shallow Slope Angle Slope Angle Note: Notice that entire part is being cut
86Steep / Shallow Slope Angle The cutting passes are being restricted to the angle settings

96Arc filter / Tolerance Toolpath Fillets Toolpath Fillets: Theoretical fillets are created in sharp corners to keep the tool motion smooth and allow flat cutters to be used in roughing where fillets weren’t created in the model.
