Start the programm and control the machine during operation.Measuring of the pieces using the control and measurement instruments (calipers, micrometers). Using the lifting equipments (cranes, forklift truck). Cleaning and maintenance of the machine and all around.

Programming (base) to the board of the machine.

In this company, I started for the first time to create small programms for easy components. My boss was my teacher on board of the machine (Nicolas Corea). My experience in programming Heidenhain is 1 year and it was a good start. Preparing machine control of oil axes, water, and air filters. Study the drawing and decide how to do on the piece. Preparing the fix installation for the piece. Input in magazine the right tools ( mills,drills, taps, definition tools for diameter in tolerances, etc). Open Tool Table and complete features of each tool that we will use (length,diameter, radius, number of inserts, etc). Center the piece on the work-table using the clock-comparator. Establish the origin point and zero axes for machine and for the piece (x0, y0,z0,B0,w0) using the clock-comparator or Touch Probe in Automatic Original Points.Open a new file and starting to write new programm. Creating a name-code of new programm base on code of drawing. Establish and write start-position-coordinate for first movements. Call first tool. Input the parameters (Speed and Feed-Rate), call M codes for refrigerants tool, sense of rotation. Call the right cycles based on how we need to do (circular pocket, linear milling, drill or tap circles, contouring cycles, etc.). Input the features required in the cycles. Establishing repetition of the cycles and under programms. Repeat this operations for each tool. If necessary, insert parameters for rotation of the work-table and spindle-head in right angle required in drawing. When we consider that everything is OK, we go to the next and very important step:

PIECE TEST.

We have to control one more time everything in our programm.

Put the Feed –Rate in slow movement, select SINGLE BLOCK function and start the programm, fallowing every movement of the machine step by step. Stop the machine urgently, if something is wrong or strange. When the programm-running is finish, we have to check all measures using the calipers or micrometers. If something is not in right tolerances, we can modify in the programm writing the good parameters or compensation. Than, we can optimize the programm to obtain maximum efficiency and work-time. Save the programm on hard and floppy.
