Adjust operation parameters (tool selection, machining heights, etc) Assign geometry to appropriate finishing operation(s) Assign geometry to roughing operation(s) Define stock size (must match physical material to be milled) Verify location of geometry relative to file origin Open template file (material appropriate) Non-ferrous metals (aluminum, brass, copper) A special template is provided for milling flat stock materials, such as single sheets of plywood or MDF.Wood Context Model Milling Template - Without Sample Geometry (2020)Wood Context Model Milling Template - With Sample Geometry (2020)Wood Flat Stock 2D Milling Template - With Sample Geometry (2020)The GSD FabLab does not currently provide templates for less frequently machined materials, though we do maintain tooling to work with the following: The wood template should be used for all wood and wood products, including softwoods, hardwoods, plywood, oriented strand board, and medium density fiberboard. The foam template should be used for all densities and types of foams, including extruded polystyrene, expanded polystyrene, and high density polyurethane.Foam Context Model Milling Template - Without Sample Geometry (2020)Foam Context Model Milling Template - With Sample Geometry (2020) It is necessary to separate the two, because the material qualities and behaviors vary greatly and require different tooling and parameters for successful milling. Submit file to online queue for approval and schedulingThe GSD FabLab provides MasterCAM templates with and without example geometry, for both Foam and Wood projects.
Assign a part perimeter chain as the input geometry. In this circumstance, it is necessary to partially clear away the stock outside the part perimeter before proceeding to the finishing operations.The Contour 2D operation may be used for roughing as follows: Contour 2D - Multi PassWhen stock thickness exceeds the shoulder length of the tools, the surrounding uncut stock may interfere with toolpaths drawn on the perimeter of the part, causing collisions. A roughing operation uses large diameter tools and coarse settings, and should not cut all the way down to the drive surface(s), instead leaving a small offset for the finishing operations to clean up afterwards. 3D geometry will typically need to include one as the first operation, while 2D geometry may not. Zadania matematyczne dla kl 2Set Parameters > Linking Parameters > Depth to = 50% stock thickness. Set Parameters > Multi Passes > Rough > Spacing = 50% of tool diameter. Set Parameters > Multi Passes > Rough > Number = 3 Enable Multi Passes in the operation parameters. Adjust Compensation such that the toolpath is drawn outside the part. Typically 3/4" Flat Upcut Endmill Users must review them and determine which operations are appropriate for their geometry. Finishing operations must be employed on a case-by-case basis, as the utility of each operation type varies from one file (and geometry) to the next.See reference pages (linked above) for a detailed explanation of concepts and usage that are common across all operation types.Commonly used finishing operations are listed below. Finishing operations clean up the extra material purposefully left behind by the roughing operation. Most MasterCAM files need at least one and frequently several separate finishing operations to produce an acceptable part. As sloped geometry becomes steeper, the toolpaths get closer together as that geometry becomes more shallow, the toolpaths are spaced farther apart.This operation is often paired with a flat endmill for use on vertical building faces. Surface Finish ContourUsed primarily to clear material from vertical or steep features.The Surface Finish Contour operation cuts geometry by offsetting toolpaths away from the drive surface at incremental heights. The toolpath can be drawn in any angle relative to the XY origin.This operation is often used with varying stepovers and machining angles to create surface patterns on site models. Harder materials require smaller stepdown.Value should not exceed tool diameter, and must be appropriate for stock material. Default is 0.125" for both values.Input values appropriate for stock thickness.Top of Stock = Stock Thickness Rough Parallel Parameters (Third Tab)Select One Way if stock material is non-uniform (wood, other materials with grain), or Zigzag if stock material is uniform (foam, plastics, mdf)Value should not exceed flute length of tool, and must be appropriate for stock material. Surface Parameters (Second Tab)Input a positive offset for both Drive and Check surfaces. Harder materials require shorter tools.Special tools are available for roughing solid wood, plywood, and mdf. FLIP plane must be defined in Plane Manager.Select largest diameter flat upcut endmill to remove material quickly. Powershell windows 10 toast notificationsSurface Finish ContourSelect largest diameter flat endmill that can maneuver completely around input geometry while producing desired resolution. Value should never be negative.Change value to match grain direction of stock if cutting method is One Way and stock material is non-uniform. If plunging, should not exceed Stock Thickness - Shoulder Length of Tool. Value should never be negative. If plunging, should not exceed Stock Thickness - Shoulder Length of Tool. Surface Parameters (Second Tab)Top of Stock = Stock Thickness Finish Contour Parameters (Third Tab)Maximum Depth = Height of deepest desired cut relative to origin. Harder materials require shorter tools.Top of Stock = Stock Thickness Finish Shallow Parameters (Third Tab)Select One Way if stock material is non-uniform (wood, other materials with grain), or 3DCollapse if stock material is uniform (foam, plastics, mdf).
