Chapter 1 Theory on CNC machines
MC Model Theory on CNC machines This chapter describes: • How to name the axes of the machine. • What machine reference zero and part zero are. • What “Home Search” is. • What travel limits are. • How to preset a part zero. • Which are the work units. > Programming units > Spindle speed. > Axis feedrate.
MC Model Theory on CNC machines 1.1 Machine Axes. The orientation of the axes depends on the type of machine and are established by the “rule of the right hand”. Axes orientation. Rotary axes.
MC Model Theory on CNC machines This manual uses the following axes configuration. Two types of movements can be distinguished on a machine, those of the machine (X, Y) and that of the tool itself (Z). But for programming them, let us assume the movements of the tool with respect to the machine.
MC Model Theory on CNC machines 1.2 Machine reference zero and part zero. They are the references the machine needs in order to work: Machine ref. zero (OM) It is set by the manufacturer and it is the origin point for the axes. Part zero (OP) It is set by the operator. It is the part’s origin or datum point with respect to which the movements are programmed. It could be set anywhere on the part.
MC Model Theory on CNC machines 1.3 Home Search. When the CNC is off, the axes may be moved by hand or by accident. In these situations, the CNC no longer keeps track of the real position of the axes. That is why a “Home Search” should be carried out on power-up. When searching home, the axes move to the home point set by the manufacturer and the CNC assumes the value of the coordinates set by the manufacturer for that point. Home Tool ref. = Home Tool ref. OM OM Machine Ref.
MC Model Theory on CNC machines 1.4 Travel limits. There are two types of limits: – Hard limits: Mechanical limits set on the machine to prevent the carriage from moving beyond the ways (cams and hardstops). – CNC limits: Set at the CNC by the manufacturer to prevent the carriage from running into the machine’s hard limits.
MC Model Theory on CNC machines 1.5 Part zero setting. The Part zero is set on all three axes. When machining several parts, the distance from Machine ref. zero (OM) to the part is different for each one. A different program would be needed for each part. By programming from Part zero (OP), it would be independent of the actual location of the part. OM Programming gets complicated when done from Machine ref. zero (OM) and it is only good for that part in that particular location.
MC Model Theory on CNC machines 1.6 Work units. Programming units They are set by the manufacturer and may be in millimeters or inches. Sindle speed The spindle turning speed is programmed in RPM. Axis feedrate The feedrate of the axes (F) is programmed in m/min.
Chapter 2 Theory on tools
MC Model Theory on tools This chapter describes: • What the tool turret is. • What the tool table is and what information it contains. • What tool presetting is. • Defects due to errors in the tool table. > Due to wrong tool calibration. > Due to wrong tool radius values.
MC Model Theory on tools 2.1 Tool management. The tools to be used with this CNC may be placed in a tool magazine. Depending on whether the machine has or not a tool magazine, the tool change may be carried out as follows: – If the machine does not have a tool magazine, the tool change is manual (like on a conventional machine). – If the machine has a tool magazine, the CNC manages the tool change automatically.
MC Model Theory on tools 2.2 Tool table. The tool data is stored in the tool table. When a tool change takes place, the CNC assumes the data set for that tool. The data shown in the table is: T: TOOL NUMBER D: OFFSET ASSOCIATED WITH THE TOOL It defines the tool dimensions. L: Tool length. R: Tool radius. I: Radius wear. K: Length wear.
MC Model Theory on tools NOMINAL LIFE Machining time or number of operations that could be carried out with the tool. REAL LIFE Machining time or number of operations carried out. FAMILY Tools with similar characteristics. STATUS Tool type: •N: Normal. •S: Special. Tool status: •A: Available. •E: Expired. (Real life > Nominal life). •R: Rejected by the PLC. This data is updated by the CNC. The operator cannot change them.
MC Model Theory on tools 2.3 Tool calibration. Tool calibration refers to the operation used to indicate to the CNC the length of the tool. This operation must be carried out properly so the parts come out with the right dimensions and the same point is controlled after a tool change. Different tool dimensions, same point.
