If an attempt to verify dirty operations is made, MasterCAM will prompt the user to regenerate with a pop-up dialogue.
Verification using dirty operations is inaccurate and should be avoided. Verification aka Simulation is the process of playing out the generated toolpaths in a virtual environment in order to check for errors and omissions. Successful verification accurate stock and tool definitions, no collisions found is a necessary pre-requisite to performing any real CNC machining at the GSD. Student submitted jobs will not be approved or scheduled until successful verification is demonstrated.
Select all operations that have been configured and will be used. Operations will be verified in chronological order according to their order in the Toolpath Manager. Click verify selected operations in the Toolpath Manager to open the Mastercam Simulator window.
Users can scrub backward and forward along the timeline by clicking and dragging the red slider, or incrementally by pressing B backward and S forward. Users may skip to the previous or next operation by pressing P previous and N next. Ensure that collision checking is activated before starting the simulation:.
During simulation playback, areas of the stock involved in a collision will be colored dark red. The type of collision can be identified in the Collision Report. An immediate collision upon simulating an operation Flute Length - In Progress Stock is typically the result of incorrectly defined Machining Heights within that operation.
MasterCAM Simulator provides an estimate of total run time for selected operations based on specified feed rates, stepover, stepdown, etc. This estimate is displayed in the Move List panel on the right. After playing through the simulation, check "Elapsed Time" for the time estimate. Often this estimate is too low by a factor of 2, so as a rule of thumb, double the MasterCAM Simulator time estimate when making a CNC appointment reservation.
Fab Lab Store. During the Milling Appointment. Be sure to let us know about any pertinent information related to the job such as material type, your deadline, stock size, or any questions or problems that you've had in making the MasterCAM file. Once submitted, pay attention to messages in your Microsoft Team as your file is being reviewed. A TA may ask you to meet with them during office hour s to discuss what you want to make; they might also ask you to make changes to your file.
The status of your submitted file can be viewed through the online queue , along with those of others, but you should also receive notifications as the job status changes. After the file is approved, you will be asked to schedule a milling appointment. Visit your job in the queue and choose the "Schedule Job" button to be brought to the scheduler. Choose a block of time that corresponds to the estimated run time for your job, as indicated by the TA in the thread posted to your Microsoft Team.
Make sure you purchase and prepare your material prior to your milling appointment allow 24 hours for most adhesives to fully cure or dry. You must be present in L33 while the machine creates your part. Pages Blog. Space shortcuts How-to articles. Child pages. CNC Tutorial.

Machining Heights Input values appropriate for stock thickness.
Stepover Value should not exceed tool diameter, and must be appropriate for stock material. Angles can be expressed in degrees, minutes and seconds, which is abbreviated, DMS. It's important to know which quadrant the part is in because the sign of the coordinates changes based on the quadrant.
As shown in Figure: 8, all points in quadrant I , have positive X and Y values. Points falling in quadrant II have negative X and positive Y values, and so on.
Figure: 8 Turn to the end of this chapter and complete; l l Exercise , Cartesian Coordinate System. Exercise , Incremental Positioning. The drawing below shows the datum in the lower-left corner, locating the part in the first quadrant as shown in Figure: 9. Figure: 9 Note: Even though part prints do not show dimensions as negative numbers, you must input negative values when appropriate.
For example, the hole in the upper left corner in the drawing below is at the coordinate: X. The following drawing shows the same part with the datum in the upper-left corner, locating the part in the fourth quadrant. For example, it is common to place the Datum at the center of round parts as shown in Figure: Figure: 10 Since most parts get installed into an assembly, the Datum ensures that critical dimensions are held for proper fit and function.
In the example below, the critical dimensions are between hole centers in reference to the 0. Thus, the engineer selected the center of this hole as the Datum as shown in Figure: Figure: 11 Note: Attention to the datum is essential to part quality.
Usually the same datum used to dimension the part is also used for machining. It extends, for all practical purposes, infinitely in all directions. Its position and orientation never change. Within this coordinate system, any number of Planes, called Construction Planes, can be defined. A Plane can be located and oriented anywhere within the coordinate system. Planes make drawing easier and are required to define certain 2D entities. Figure: 12 Examples in this chapter use the predefined plane, Top.
Select the Top Plane by clicking on Plane on the status bar and picking Top from the list. Note: You can view the coordinate system axes by selecting F9 or File, Configuration, Screen, Display part information.
Screen Grid shows the position and orientation of the active Cplane. Wireframe geometry includes information only about the edges of a part. Wireframe models cannot be shaded. A surface can be thought of as an infinitely thin shell stretched over a wireframe.
Surface geometry includes information about the faces and edges of a part. There are many types of surfaces; each suited to model a specific type of shape. Surfaces are used to model complex, freeform organic shapes common in the automotive, aircraft, mold, and consumer goods industries. Surface modeling is covered in the Mastercam Handbook, Volume 2. Solids contain information about the edges, faces, and interior of the part.
Solids are able to model many parts, but some highly sculpted shapes, like car bodies, may still require surfaces. All Solids start with profiles of wireframe geometry. Solids are covered in Chapter 5, Solid Modeling. Entity Definition Point A point occupies a single set of coordinates in space.
It has no length, depth, or width; it is infinitesimally small. Line Arc Spline Drafting A line is an entity defined by any two points in space, called endpoints.
Lines have length, but no width or depth; they are infinitely thin. An arc is an entity that is equidistant from a point in space, called a center point. Arcs are "2D" entities, meaning that they must lie on a plane. A Spline is a curve that travels, usually smoothly, through a set of points, called Control Points. There are two types of splines; 2D and 3D. Drafting entities include notes, text, leader lines, witness lines, and hatchs. They are used to annotate a drawing. Drafting text and notes are stored as a special entity type called a font, which allows lettering to be stored in an efficient format.
Wireframe geometry includes other geometry types, such as a helix, ellipse, and rectangle. However, these are modeled using one of the basic entity types described above. For example, an ellipse is modeled using a spline, and a rectangle is modeled using four individual lines. This chapter deals with how to create basic wireframe geometry types listed in the table above. Once you understand these, it will be easy for you to create other types. Figure: 13 shows the commands used to create wireframe geometry.
The commands are arranged in groups based on entity types or specific activity. The groups are displayed in the ribbon from basic to more complex functions. A line can start and end anywhere in the Mastercam Coordinate System as shownFigure: Full length of the line, regardless of the view.
If the line lies in the same plane that it is being viewed, the 2D and 3D lengths are the same. The angle of a line is measured from the position. Counterclockwise CCW angles are positive. Clockwise CW angles are negative.
