• Possibility of graphical verification of the program on the machine.

Day 4 (theory and practical applications in the room and on the machine)

• Syntax of executing a program
• Calling a program already existing in memory
• Introducing a new program in memory
• Modifying an existing program
• Applications on the machine of the above functions
• Choosing a part by the customer
• Establishing the steps for executing the part
• Choosing cutting tools
• Executing the part program
• Executing the part
• Final measurements
• Analysis + optimizations
• Theoretical and practical examination

Legend: activity on the machine; activity in the room
The course is effective for a group of no more than 4 people, so that the applications on the machine are accessible to everyone. For a larger number of participants, the number of days will increase, to give all participants the opportunity to understand the application on the machine. CNC machines considered: MILLING MACHINE, controller FANUC
