A. basic introduction to the relevant machine tool (i.e. machining centre or lathe);
B. An explanation of machine tool and machining terminologies and principles;
C. An introduction to the specific CNC control and its functions;
D. An understanding of offsets (i.e. workpiece and tool length etc.) including how to set and adjust parameters;
E. Health and Safety compliance and best practice.

Standard Siemens Shopturn Programming content.

Using the Siemens’ ShopTurn function helps fast and efficient programming. The course consists of step-by-step instructions beginning with basic principles and gradually increasing in complexity. Specific descriptions and programming examples will also be covered in the course.

By the end of the course, you should be able to program components to a reasonable standard, thus achieving the full potential of your CNC turning centres.

Applicants should have a basic knowledge of Engineering and an understanding of component drawings would be advisable.

Specific course content includes: Introduction and General Layout of Machine Operator, Keyboard and Soft-key Explanation Axes Configuration X, Z, C and Y if required Modes e.g. T, S, M and MDA and Program Manager Tool List Creation and Editing and Work Offset Menus Create Shop Turn Program with Program Header Planning the Machining Process and Structure Contour Turning and Utilising Shop Turn to include Turning, Facing and Boring Cycles Hole Machining with Drilling, Tapping Cycles etc. Simulating and Troubleshooting Programs Grooving, Part Off, Threading Cycles Drilling, Tapping and Thread Milling Cycles Using C or Y Axis Pocket, Spigot and Engraving Milling Cycles Using C or Y Axis Set Marks, Repeats in Sub Routines Transformations Offset, Rotation Mirroring etc. Explanation of Counter Spindle and Transfers if required Description of M codes relative to type of Machine Examples Utilising the Above USB communication to machine

Advanced Siemens Shopturn Programming content.

Using the Siemens’ ShopTurn function, along with ISO codes and Parametric functions, helps fast and efficient programming. The course consists of step-by-step instructions beginning with basic principles and gradually increasing in complexity. Specific descriptions and programming examples will also be covered in the course as well as showing both turrets working simultaneously. Subjects covered in the course include:

Milling and drilling on angles
Working both sides
Balanced machining times
By the end of the course, you should be able to program components to a reasonable standard, thus achieving the full potential of your CNC Twin Spindle and Twin Turret turning centres.

Applicants should have a basic knowledge of Engineering and an understanding of component drawings would be advisable.
