Catalog Description:

MTT 3554 - Surface Toolpaths (3 hrs.)

This is an advanced course designed to give the student an understanding on surface machining. It will build on information from the beginning classes and on wireframe/surface creation.

Course Classification:



MTT3553 3D Wireframe Drawing and Surfaces or instructor approval.

Controlling Purpose:

This course is designed to help the student increase his/her knowledge concerning the use of Mastercam to program complicated parts for machining and to make efficient use of machining time.

Learner Outcomes:

Upon completion of the course, the student will be able to create programs, using surfaces that will run efficiently on CNC machine tools.

Unit Outcomes for Criterion Based Evaluation:

The following outline defines the minimum core content not including the final examination period. Instructors may add other material as time allows.


Outcomes: Upon completion of this course, the student will be able to demonstrate the ability to describe the 8 surface roughing functions, create surface toolpaths, and verify them.

  • Explain the 8 surface roughing functions.
  • Describe the features of the eight surface roughing functions.
  • List the parameters used in surfacing toolpath function.
  • Demonstrate each of the surface roughing functions.
  • Demonstrate verifying roughing toolpath.


Outcomes: Upon completion of this course, the student will be able to demonstrate the ability to create surface finish toolpaths, set stock parameters, and verify toolpaths.

  • List the restmaterial parameters.
  • Explain how mastercam computes remaining stock.
  • Verify finish toolpaths.


Outcomes: Upon completion of this course, the student will be able to demonstrate the ability to explain what drive surface, open edges, max step-down parameter, causes of gaps, and demonstrate the use of check surfaces.

  • Explain what a drive surface is.
  • Demonstrate the use of check surfaces.
  • Explain the max stepdown parameter.
  • Explain possible causes of gaps.
  • Explain what is meant by open edges.

Attendance Policy:

Students should adhere to the attendance policy outlined by the instructor in the course syllabus.

Grading Policy:

The grading policy will be outlined by the instructor in the course syllabus.

Maximum class size:

Based on classroom occupancy.

Course Time Frame:

The U.S. Department of Education, Higher Learning Commission and the Kansas Board of Regents define credit hour and have specific regulations that the college must follow when developing, teaching and assessing the educational aspects of the college.  A credit hour is an amount of work represented in intended learning outcomes and verified by evidence of student achievement that is an institutionally-established equivalency that reasonably approximates not less than one hour of classroom or direct faculty instruction and a minimum of two hours of out-of-class student work for approximately fifteen weeks for one semester hour of credit or an equivalent amount of work over a different amount of time.  The number of semester hours of credit allowed for each distance education or blended hybrid courses shall be assigned by the college based on the amount of time needed to achieve the same course outcomes in a purely face-to-face format.
