1 Introduction 9 1 Introduction 1.1 The Part Program The Part Program is a set of instructions that can be interpreted by the control system in order to control the operation of the machine. The Part Program consists of blocks which, in turn, comprise words.
1 Introduction 10 Block A block is made up of words. The blocks are separated by characters s ( L ine F eed) in the memory. The use of a block number is not mandatory in the blocks.
1 Introduction 11 return from the sub-program to the calling program. DNC Channel A program contained in an external unit (e.g., in a computer) can also be executed without storing it in the control's memory. Now the control will read the program, instead of the memory, from the external data medium through the RS232C interface.
1 Introduction 12 Fig. 1.2 -1 Fig. 1.2 -2 Fig. 1.2 -3 1.2 Fundamental Terms The Interpolation The control system can move the tool along straight lines and arcs in the course of mach- ining. These activities will be hereafter referred to as "interpolation".
1 Introduction 13 Fig. 1.2 -4 Fig. 1.2 -5 Reference Point The reference point is a fixed point on the machine-tool. After power-on of the machine, the slides have to be moved to the reference point. Afterwards the control system will be able to interpret data of absolute coordinates as well.
1 Introduction 14 Fig. 1.2 -6 Fig. 1.2 -7 Absolute Coordinate Specification When absolute coordinates are specified, the tool travels a distance measured from the origin of the coordinate system, i.e., to a point whose position has been specified by the coordinates.
1 Introduction 15 Fig. 1.2 -8 the code of G90 (absolute data specification) and the value of F (Feed), specified in block N15, will be modal in blocks N16 and N17.
1 Introduction 16 Fig. 1.2 -9 Cutter Radius Compensation Machining a workpiece has to be done with tools of different radii. Radius compensation has to be introduced in order to write the actual contour data of the part in the program, instead of the path covered by the tool center (taking into consideration the tool radii).

2 Controlled Axes 18 The rotational axes are always provided with degrees as units of measure. The input increment system of the control is regarded as the smallest unit to be entered. It can be selected as parameter. There are three systems available - IS-A IS-B and IS-C.

14 The Tool Compensation 101 Fig. 14.5.7 -1 Fig. 14.5.7 -2 14.5.7 General Information on the Application of Cutter Compensation In offset mode (G41, G42), the control will always have to compute the compensation vectors between two interpolation blocks in the selected plane.

14 The Tool Compensation 103 Fig. 14.5.7 -6 Fig. 14.5.7 -7 The path of tool will be as follows when instructions G22, G23, G52, G54-G59, G92 G53 G28, G29, G30 are inserted between two interpolations.
14 The Tool Compensation 104 Fig. 14.5.7 -8 Fig. 14.5.7 -9 If G28 or G30 is programmed (followed by G29) between two blocks in offset mode, the compensation vector will be deleted at the end point of .

14 The Tool Compensation 106 Fig. 14.5.7 -13 Fig. 14.5.7 -14 When a full circle is being programmed, it may often occur that the path of tool covers more than a complete revolution round the circle in offset mode. For example, this may occur in programming a direction reversal along the contours: .
14 The Tool Compensation 107 Fig. 14.5.7 -15 Fig. 14.5.8 -1 Two or more compensation vectors may be produced when going around sharp corners. When their end points lie close to each other, there will be hardly any motion between the two points.
14 The Tool Compensation 108 Fig. 14.5.8 -2 Fig. 14.5.8 -3 In the other words the control will check wether the compensated displacement vector has a component opposite to the programmed displacement vector or not.
14 The Tool Compensation 109 Fig. 14.5.8 -4 If parameter ANGLAL is set to 0, the control will not return an error message, but will automatically attempt to correct the contour in order to avoid overcutting. The procedure of compensation is as follows.

14 The Tool Compensation 111 Fig. 14.5.8 -8 In the above example an interference error is returned again because the displacement of the compensated path in interpolation B is opposite to the programmed one.
14 The Tool Compensation 112 Fig. 14.6.2 -1 Command G40 or D00 will cancel the three-dimensional offset compensation. The difference between the two commands is that D00 will delete the compensation only, leaving state G41 or G42 unchanged.
14 The Tool Compensation 113 Instruction G42 functions in the same manner as G41 with the difference that the compensation vector is computed in a direction opposite to G41: A change-over from state G41 to G42 or vice versa is only feasible in a linear interpolation block.
