7 Programming with Q Parameters 7-2 Q Parameters are used for: • Programming families of parts • Defining contours through mathematical functions A family of parts can be programmed in the TNC in a single part program. You do this by entering variables — called Q parameters — instead of numerical values. Q parameters can represent for example: • Coordinate values • Feed rates • Spindle speeds • Cycle data A Q parameter is designated by the letter Q and a number between 0 and 113. Q parameters also enable you to program contours that are defined through mathematical functions. With Q parameters you can make the execution of machining steps dependent on logical conditions. Q parameters and numerical values can also be mixed within a program. Fig. 7.1: Q parameters as variables The TNC automatically assigns data to some Q parameters. For example, parameter Q108 is assigned the current tool radius. You will find a list of these parameters in chapter 12.. Q1 Q3 Q5 Q6 Q4 Q2 TNC 360
7 Programming with Q Parameters 7.1 Part Families — Q Parameters Instead of Numerical Values TNC 360 The Q parameter function FN0: ASSIGN is used for assigning numerical values to Q parameters. Example: Q10 = 25 This enables you to enter variable Q parameters in the program instead of numerical values. Example: L X + Q10 (corresponds to L X + 25) For part families, the characteristic workpiece dimensions can be programmed as Q parameters. Each of these parameters is then assigned a different value when the parts are machined. Example Cylinder with Q parameters Cylinder radius R = Q1 Cylinder height H = Q2 Cylinder Z1: Q1 = +30 Q2 = +10 Cylinder Z2: Q1 = +10 Q2 = +50 To assign numerical values to Q parameters: Q DEF FN0: ASSIGN e.g. 5 e.g. 6 ENT PARAMETER NUMBER FOR RESULT? ENT FIRST VALUE / PARAMETER? ENT Resulting NC block: FN0: Q5 = 6 Fig. 7.2: Workpiece dimensions as Q parameters Open a new block with the function FN0: ASSIGN. Enter Q parameter number. The value to the right of the equal sign is assigned to the Q parameter to the left. Q1 Q2 Q2 Z1 Q1 Z2 Enter value or another Q parameter whose value is to be assigned to Q5. 7-3
