Cutting Tool Selection Criteria for Cylindrical Gear Manufacturing

This paper is divided into two parts. The first part is a general digression on the pressure angle on cylindrical gears. The pressure angle is a variable that plays an important role in defining the geometry of gears and hobs, yet it is not widely discussed. This introduction serves as a prerequisite for the second part of the paper. The second part will show an application case of choosing the most suitable hob to cut a given gear. In this selection process, particular attention will be paid to the pressure angle of the hob for cutting with modified rolling, i.e., with a reduced pressure angle compared to that of the gear.

Design

The conjugacy of meshing gears is one of the most important attributes of gears because it ensures a constant velocity ratio that gives smooth, uniform transmission of motion and torque. Some of the world’s greatest gear theoreticians like Earle Buckingham, Wells Coleman, and John Colbourne laid the foundation for understanding conjugacy. Their teachings and interpretations of the law of gearing have been used by generations of gear engineers to design and manufacture gear transmissions for almost everything that is mechanically actuated. 

Grinding

The way to increase production, especially with the largest gears, is to decrease nonproductive time with improved strategies.

Inspection

In conventional gear manufacturing, quality control is carried out for a number of pieces per batch. Most parts enter final gearbox assembly without any inspection. Among other things, this approach is based on two facts: measuring time is significantly longer than the machining time, and the limited measuring capacity available.

Heat Treating

Quality control, EV components, energy consumption and material influences are just a handful of topics being discussed in heat treating today. New heat treat methods and global trends will be the topic of conversation later this year at Heat Treat 2023. Here’s a round-up of some stories circulating across key market segments.

Product News

Inspection using a coordinate measuring machine (CMM) in a production environment brings enormous advantages compared with transporting components, sometimes considerable distances to a separate quality control (QC) room. Benefits include faster inspection, quicker reporting, reduced lead times, rapid feedback on part conformity for prompt adjustment of manufacturing processes, increased output, reduced scrap and raised efficiency. Eliminating the need to transfer parts to another location saves labor costs and time, reducing the risk of damaging the parts being handled. It also allows the QC function to be closely integrated with production and automated if desired.
