CNC Multi Axis

CNC 260

CNC Multi Axis

CNC 260

Course Description

Prerequisites: Prerequisites: CNC 225 and CNC 216 or instructor permission.

Introduces and demonstrates concepts for multi axes machining techniques beginning with 3 plus 2 axis utilizing planes then advancing to true 5 axis machining. Imports engineering drawings and electronic CAD files into CAM software to perfect geometry and tool path routines, then outputs G-code specific to the multi-axes machine. Focuses on complex applications and the true efficiency of multi-axes machining through individual and/or team assignments. Credit may be earned in CNC 260 or SKCN 260 but not both. (30-30)

Outcomes and Objectives

Demonstrate the ability to determine which multi axis machine tool to use for the job.

Objectives:

  • Identify the different axes available in the machine tool.
  • Select the proper machine for the job.

Demonstrate the ability to conceptualize a part in 3 dimensional space.

Objectives:

  • Identify features on a part and determine proper machinery to use.
  • Relate the part to the machining processes and demonstrate understanding of the reasoning behind choosing a particular machine.
  • Show proficiency in plane manipulation.

Demonstrate the ability to create part geometry using solids and surfaces with CAM software in 3 dimensional space.

Objectives:

  • Select the best geometry creation technique for the part features to be machined.
  • Create geometry using proper drawing techniques appropriate for multi-axis tool pathing

Demonstrate proper tool path selection for the application based on part geometry.

Objectives:

  • Determine proper tool path for material removal.
  • Select proper tooling from tool library.

Demonstrate the ability to use CAM software to back plot and verify for axis and tool motion control.

Objectives:
