Use the Defaults for Milling dialog to specify default machining parameters, such as group and process parameters, for milling.
Select Job Optimizer > Defaults to display this dialog.
Use these options to set the default values for new workgroups created in a Milling Face window. PartMaker uses these default values on the Hole Group Parameters dialog and the Profile Group Parameters dialog.
Through Hole — When this option is selected, the default is to create through holes. When the option is not selected, the default is to create blind holes.
Diameter — The default hole diameter.
Chamfer — The default chamfer size.
Z_Surf — The default distance from the zero point to the part surface (top of the part).
Z_Depth — The default hole depth.
Z_Rapid — The default distance from the tip of the tool to the part surface when the tool performs rapid moves.
Z_Clear — The default clearance between the tool starting point and the part surface.
Width of Cut — Specify how you want the Width of Cut value on the Profile Group Parameters dialog (Milling) to be defined when creating profile groups for pockets, contours and face milling:
Width of Cut Value — If you have selected %Tool Diameter as the method of specifying the Width of Cut Value, specify the defaultpercentage value you want to use in this field.
Advanced 2D Milling Defaults — Click this button to set default values for advanced milling on the Advanced 2D Milling Defaults dialog.
Surfacing Defaults — Click this button to set default values for surface machining on the Surfacing Defaults dialog.
Use these options to set the defaults for milling processes created in the Process Table. These defaults are used on the Process Parameters dialog:
Apply Comp in PartMaker — Select this option if you want PartMaker to apply cutter diameter compensation.
Coolant — The default coolant type for machining (High Pressure, Standard or None).
Feed — The default feed rate for all tools.
Speed — The default RPM (spindle speed) for all tools.
Tool Ch X — The default tool change position in the X direction.
Tool Ch Y — The default tool change position in the Y direction.
Tool Ch Z — The default tool change position in the Z direction.
Modify Feed rate on Arcs — Click to display the Modify Feedrate on Arcs dialog. Use this dialog to set the feed rate modification parameters for all processes in the job file.
Maximum Speed — The default maximum RPM value used for machining.
Maximum Feed — The default maximum feed rate value used for machining.
Tool Change Time (min) — The default tool change time in minutes to be used during machining.
Rapid Feed — The default rapid feed rate to be used for machining. This is used as the default value for Advanced Surface Machining processes and processes created from toolpaths imported from PowerMill.
Arc Radius — The radius of the arc of the lead.
Line Length — The length of the line of the lead.
Lead Angle — The angle between the line and the profile of the lead. It is the same as the angle of the arc of the lead.
Process Table Display Option
Feeds in Units per Revolution and Surface Speed — Select this option if you want the Process Table to display feeds in units per revolution (upr) and speeds in surface speed (that is, feet per minute (fpm) or meters per minute (mpm)).
Arc Tolerance — The chord tolerance to be used while breaking arcs into lines.
Corner Rounding — Specifies whether toolpaths will have rounded, or sharp, corners.
